SECTION 3 MANAGEMENT PROGRAMS

Transcription

1 SECTION 3 MANAGEMENT PROGRAMS The contractual relationship between the City of Indianapolis and United Water facilitates effective planning and goal setting for all aspects of the city s collection system and treatment plant programs. We have instituted many programs to establish a sound management structure in both organizations. These programs, described in this section, ensure the city and United Water have: sufficient legal authority to implement CMOM-related programs, sound policies and planning to assess sewer conditions and ensure adequate capacity, design and performance standards to ensure quality and consistency, wet weather overflow management programs to track, report and evaluate system overflows in order to prevent or minimize their recurrence, training and safety measures to equip and protect both management and staff; adequate resources and funding to implement capital and operational programs, an up-to-date information management system to track infrastructure and maintenance activities, maintain accurate GIS mapping, and generate reports to monitor both sewage infrastructure conditions and operation and maintenance activities customer service programs to respond to public needs and to provide public education and involvement, water quality monitoring to monitor system performance and environmental impacts, and emergency response planning to prepare for all contingencies. These policies and programs are described in greater detail below. Balanced Scorecard: United Water and city management are developing a Balanced Scorecard to track key benchmarks for the wastewater treatment facilities and the collection system. A balanced scorecard is an approach to strategic management that was developed in the early 1990's by Drs. Robert Kaplan (Harvard Business School) and David Norton. The balanced scorecard is a management system designed to enable organizations to clarify their vision and strategy and translate them into action. The scorecard will include key performance indicators related to the following management goals: Environmental Compliance Collections Contract Compliance AWT Contract Compliance Collections Performance After studying business strategies used by the most successful international organizations, United Water selected the balanced scorecard concept to improve the operations and maintenance of the Indianapolis collection system. The balanced scorecard supplements traditional financial measures with criteria that measure performance from additional perspectives. Customers, internal business processes, and learning and growth are used to link a long-term vision. This enables the tracking of financial results while simultaneously monitoring progress in building capabilities and acquiring intangible assets. Indianapolis CMOM Program Report /20/2004

2 The balanced scorecard is enabling United Water to align management processes and focus on implementing long-term strategy. The scorecard has provided managers with a central framework around which they could redesign each piece of the management system. 3.1 Legal Authority The U.S. Environmental Protection Agency (U.S. EPA) has the authority to delegate certain authorities under the Clean Water Act to state agencies that meet federal requirements. In Indiana, U.S. EPA has delegated that authority to the Indiana Department of Environmental Management (IDEM). The Indiana Code at IC (Appendix 3-1) authorizes IDEM to administer Clean Water Act activities, including the permitting programs under the National Pollutant Discharge Elimination System (NPDES). IDEM has issued two permits to DPW and its contract operator, WREP/United Water, to operate its collection system and to discharge treated plant effluent from the Belmont and Southport Advanced Wastewater Treatment Plants to the West Fork of the White River, in accordance with effluent limitations, monitoring requirements and other conditions set forth in the permits (Appendix 3-2 and Appendix 3-3). The Consolidated City of Indianapolis has the legal authority, through sewer use ordinances and sewer service agreements, to establish and implement programs relating to capacity, management, operation and maintenance of sanitary, stormwater, and combined sewers within its jurisdictional boundaries. Dischargers of wastewater are regulated by Chapter 671 of the Revised Code of the Consolidated City of Indianapolis and Marion County, Indiana. Chapter 671 is included as Appendix Inflow and Infiltration The legal authority for controlling infiltration and connections from inflow sources is found in Chapter 671, Article II: Building Sewers. Some of the relevant sections include: Table 3.1 Legal Authority for Controlling Infiltration and Inflow Sec Sec Sec Sec Sec Sec Sec Sec Connection permits.

5 Sec Sec Enforcement. Permit revocation Inter-Jurisdictional Agreements The legal authority for Indianapolis jurisdiction over satellite and out-of-county sewer systems is authorized by Chapter 671, Article I: In General and Article IV: Rates, Charges and Billing. In addition IC ; IC ; IC ; and IC (14) provide the legal framework in which inter-local agreements can be reached for sewer services with satellite and out-of-county sewer systems. Table 3.6 Legal Authority for Jurisdiction over Satellite Sewer Systems Sec Sec Purpose and policy. Use by other political subdivisions. As noted earlier in Section 2.4, the city has agreements with several communities within and outside Marion County to provide sewage treatment and disposal services. Those agreements typically define the relationship between the two communities as it relates to the following issues: Service Area Construction and Installation of Improvements Residential Application Wastewater Discharge Standards Measuring, Sampling, and Testing of Wastewater Reporting Requirements Payment Maintenance of Sewer Systems Indemnification Obligations of the City Assignment Default and Remedies Special Termination Rights Dispute Resolution Condition Precedent The city s current agreements are included as Appendices 3-5 to 3-11: Agreement between the Consolidated City of Indianapolis and Hamilton Southeastern Utilities, Inc. for Sewage and Wastewater Treatment and Disposal Services.

7 Developed a comprehensive Sanitary Sewer Master Plan to prioritize and address interceptor capacity needs in the sanitary sewer area Developed a Long-Term Control Plan to reduce combined sewer overflows and improve water quality These improvements are described in more detail below and in the sections that follow Existing Sewers Asset Inventory United Water has created a more efficient procedure (Appendix 3-12) for identifying and updating the city s asset inventory in the Hansen information management system. United Water began using the procedure in 2004 to quickly identify non-inventoried structures in the collections systems. United Water will be working more closely with city personnel to get the structures into the system for quick data entry and performance reporting System Modeling The City of Indianapolis initiated its collection system modeling in The city subsequently developed a suite of modeling tools that have received significant refinement and expansion during the last 12 years to primarily support CSO long term control planning. A brief timeline of the modeling work follows : Interceptor system model development : Interceptor system optimization : Interceptor system model calibration and verification 2001: CSO Long-Term Control Plan (LTCP). Hydraulic model (SWMM) and WASP model are used for facility sizing and expected water quality performance 2001: Supplemental flow monitoring and sampling for the recalibration of the models is performed : SWMM expansion for the Southport AWT Plant and its tributary interceptors is initiated 2002: SWMM and WASP models are recalibrated. Updated SWMM parameters are incorporated into NetSTORM. Performed validation of NetSTORM with recalibrated SWMM 2004: Interplant Connection Facilities Plan. NetSTORM and SWMM are used for facility evaluation 2004: SWMM Model Expansions for the South Marion County Regional Interceptor (SMCRI) and Belmont North Interceptors are completed 2004: System Wide Plan Analysis for the Revised CSO LTCP The SWMM model was developed to provide hydraulic representation of the interceptors and regulator structures in the combined sewer area for CSO operational plan development and CSO long term control planning. Although several models are potentially available for interceptor modeling, the most widely used and accepted model for this application is the EXTRAN block of the U.S. EPA's SWMM (Roesner et al., 1988). The EXTRAN block solves the full dynamic St. Venant equations for gradually varied, unsteady flow using an explicit numerical solution technique. The hydraulic model (SWMM) of the combined sewer interceptor system is a key element for understanding and predicting the hydraulic conditions that cause raw sewage overflows. The Indianapolis CMOM Program Report /20/2004

8 model is currently used to prepare discharge monitoring reports (DMRs) for the combined sewer outfalls, as required by the city s NPDES permit. The model was first developed and calibrated from 1992 to 1996, then recalibrated in 2002 using flow monitoring data from a Supplemental Monitoring and Sampling Program. Since 1996, the model has been regularly updated to reflect new sewer system data and expanded into some of the separate sewer areas of the collection system. U.S. EPA performed extensive reviews of the 2002 model recalibration effort and approved the model for CSO Long-Term Control Plan development in June Approval of the model included expectations for continued model expansion and calibration to support detailed planning during implementation of the LTCP projects. The Indianapolis SWMM model has been refined as needed to incorporate the findings of field investigations and improved record information. Additional collection system information has been incorporated into the SWMM model to support the 2001 CSO LTCP, the DMRs, and the 2004 Interplant Connection Facilities Plan. Completion of the DMRs requires that all combined sewer system improvements made in the six-month DMR period receive functional representation in the SWMM model. In 2001 and 2002, the SWMM model was expanded to include the Southport AWT Plant and a portion of its tributary interceptors. The objective was to expand the calibrated interceptor model to include a basic representation of the interceptor sewer network immediately upstream of the plant. This effort focused on developing a working interceptor model that links the Belmont and Southport AWT Plants, which enabled the city to perform an overall planning level assessment of the flow diversion between the two plants. In 2002 and 2003, the SWMM model was expanded to include two key separate sanitary interceptors: the South Marion County Regional Interceptor and Belmont North sanitary interceptors. The expanded model will support the assessment of the current and future capacity of those interceptors and support implementation of the LTCP. The model expansion for the South Marion County interceptor is more detailed than the basic representation developed in the Southport expansion, and intended to perform overall planning level hydraulic assessments for this critical interceptor under existing and future conditions. The development and calibration of the model expansions is documented in the South Marion County Regional Interceptor Model Expansion Report (CDM, 2004), and the Belmont North Interceptor Model Expansion Report (CDM, 2004). Model expansions for additional separate sanitary interceptors will be performed as required to support the city s planning efforts. The model expansions will be performed in accordance with the guidelines established in the Hydraulic Model Calibration and Verification Plan (Indianapolis Clean Stream Team, 2003) Permanent and Temporary Flow Monitoring During 1986, a network of flow meters and rain gauges was installed throughout the sewer system in Marion County. Since then, this system has been continuously monitored and maintained by ADS Environmental Services Inc. Currently this work is included in the Agreement between the city and United Water. The monitors provide a historical compilation of flow data for use in evaluating sewer construction permit applications and evaluating sewer capacity in different areas of the city. Monitoring locations were chosen based on catchment size, sewer geography and problem areas. The program has since been expanded to include documentation of issues such as silt, debris, and bottleneck locations. Indianapolis CMOM Program Report /20/2004

9 ADS submits monthly, semi-annual and annual reports summarizing the data. An example report is provided through the link below. ADS Environmental Services Inc. February City of Indianapolis Wet Weather Report, July December (Appendix 3-13). The city also maintains a contract with a qualified consultant to perform temporary flow monitoring on an as-needed basis. The purpose of this contract is to supplement the existing network of permanent sewer flow monitors where needed to evaluate flow conditions. Contractually, the consultant is obligated to begin the monitoring within 7 days of a written request. Generally, the response time is 2 to 3 days. Night flow monitoring and smoke testing can also be accomplished. See Appendix 3-14 for an example of a temporary on-call flow monitoring contract Condition Assessment The city has conducted a number of studies to assess the conditions of sanitary sewers, combined sewers, lift stations, siphons and the AWT plants in recent years. These studies have enabled the city to identify, prioritize and implement short-term and long-term rehabilitation actions to address infrastructure needs. Sanitary Sewer Evaluation Studies: The city completed a Basin Master Plan in 1998 to prioritize general recommendations pertaining to the sanitary sewer basins from seven Sanitary Sewer Evaluation Surveys (SSESs) that had been completed previously. It continues to be the primary planning document for sewer rehabilitation. The Basin Master Plan provides the city with a framework for selecting sanitary sewer basins for future sewer investigations and for prioritizing basins for capital improvements. The SSESs evaluated the structural and hydraulic condition of the sewer systems in selected separate sanitary sewer basins. Structural conditions of the sewer systems were evaluated by methods such as manhole inspection, smoke testing and sewer televising. Hydraulic conditions were evaluated through flow monitoring and house-to-house inspections. The Executive Summary of the Basin Master Plan is included as Appendix Sanitary Sewer Evaluation Studies developed by the city follow the general format detailed in the 1994 document, Existing Sewer Evaluation & Rehabilitation. The document was prepared by a joint task force of the Water Environment Federation and the American Society of Civil Engineers, under the direction of the WEF Facilities Development Sub-committee of the Technical Practice Committee and ASCE Environmental Engineering Division Committee on Water Pollution Management. (WEF manual of practice: FD-6; ASCE manual and report on engineering practice: no. 62.) Combined Sewer Infrastructure Assessment: The city completed a detailed evaluation of combined sewers 60 inches in diameter or larger in 1996 (as Phases I & II). The project s goal was to identify, inspect, and provide a priority list for the rehabilitation of vulnerable sewer segments to reduce the potential for incidences of failure. The initial project was divided into two phases. The first phase included data review, spreadsheet and map development, sewer segment ratings, a walk-through inspection of high priority sewers, and identification of early action rehabilitation projects. The second phase included additional inspections, sewer segment ratings, a structural performance assessment and development of additional sewer rehabilitation projects. The report summarizing both phases is included as Appendix A third phase included inspections of critical sewers with diameters 48 to 60 inches, an evaluation of rehabilitation alternatives, preparation of opinions of probable construction costs, and prioritization of sewer Indianapolis CMOM Program Report /20/2004

10 rehabilitation projects. It was completed in The report is included as Appendix The city has completed many of the rehabilitation projects identified in these studies and continues to plan for additional projects through the capital improvement project (CIP) planning process. Siphon Assessment Studies: In 1994 and 1995 the city conducted several studies to evaluate and assess the conditions of siphons within the sewer system. Executives summaries for each of the following have been included as appendices: Evaluation, Assessment & Rehabilitation of Inverted Siphons for the City of Indianapolis, Indiana. Commonwealth Engineers, Inc. November (Appendix 3-18) Engineering Evaluation of Four Inverted Siphon Structures. Project No. CS ADMC. Final Report. GRW Engineers, Inc.

February (Appendix 3-21) Lift Stations: City staff reviews United Water s recommendations for improvements to lift stations on an annual basis. Needs are prioritized and funds secured as needed. Details are included in Appendix 3-22, Lift Station Corrective Action Recommendation. In addition, the city has developed detailed studies for a number of lift stations in recent years, including: Lift Station No. 403, Fall Creek and Shadeland Avenue, Sanitary Sewer System Rehabilitation Design and Hydraulic Analysis. Rust Environment and Infrastructure. City of Indianapolis, Department of Capital Asset Management. December (Appendix 3-23). AWT Plants: In coordination with United Water and regulatory authorities, the city determines the need for improvements to the treatment plants. In addition, treatment plant expansion needs have been investigated as part of the development of the city's long-term control plan for combined sewage. DPW Engineering staff also monitor conditions at the AWT plants and recommend needed improvements Industrial Pretreatment IDEM has delegated authority to the City of Indianapolis to administer the industrial pretreatment program under the Clean Water Act. This program is co-administered by DPW s Office of Environmental Services and United Water. United Water performs industrial sewer user inspection, permitting and monitoring of industrial facilities that discharge into the wastewater collection system and ultimately to the Indianapolis AWT plants. Additionally, United Water manages the Belmont AWT Liquid Waste Hauler program. The effective performance of these duties results in protection of the treatment plant s processes, protection of the White River ecosystem, as well as timely service to the regulated community. Indianapolis CMOM Program Report /20/2004

11 United Water monitors industrial facilities to ensure they are in compliance with their pretreatment permits. When issues arise with the facilities, notification is given to the Office of Environmental Services (OES). These notices to OES could result in a notice of non-compliance to the particular industry or even a referral to the IDEM or EPA, depending on the severity of the non-compliance. Significant progress was made in 2003 to eliminate chronic violations from specific industries. The implementation of enforcement procedures specified in an Enforcement Response Procedures Plan helped eliminate periodic violations from numerous industrial users. Total violations decreased by 24 percent from 2002 figures. When reviewing industrial discharge permit applications, the city considers impacts on sewer capacity and combined sewer overflows. This review takes into consideration CSO volume, pollutant load, receiving stream and the feasibility of other options. In some cases, OES has required permittees to hold discharges to the sewer system during wet weather in order to mitigate the environmental impacts of CSOs. In other cases, permit applicants have been required to find another discharge location due to capacity or increased load concerns. The city submits an annual report on the Pretreatment Program to IDEM by March 31 of each year. The 2003 annual report is included as Appendix Wastewater Haulers Program: The Industrial Pretreatment Program also regulates 76 permitted wastewater haulers. The program screens and permits the transport and disposal of residential and commercial septage waste, restaurant grease trap waste, and special discharge waste. Each load of waste disposed of at the Belmont plant is screened for acceptability. Heavy metals monitoring is performed weekly. The table below shows the amount of waste hauled to the Belmont plant in 2002 and Acceptance of hauled waste is an important part of the city s pollution prevention efforts within Marion County. If the city does not provide this service, some of these wastes may not be disposed of properly in this and/or surrounding counties. Table 3.7 Hauled Waste Program Issues Non-domestic Approvals Gallons of Septage Disposed 14,132,850 14,064,330 Gallons of Grease Disposed 1,987,816 1,850,505 Gallons of Special Waste Disposed 8,670,570 8,788, Infiltration and Inflow Control Clear water inflow and infiltration (I/I) into sanitary sewers reduces the sewage carrying capacity of sewer lines and can cause sanitary sewer overflows (SSOs) during wet weather events. Additionally the clear water in the sewer system has to be processed at the advanced wastewater treatment plants (AWTs) at a considerable expense. City Ordinance Sec prohibits clear water discharges into the sanitary sewer (inflow). Specifically, connections from foundation drains, sump pumps, roof drains, heat pump discharges, and cooling water are prohibited. DPW is seeking continuous improvement in its I/I mitigation programs, particularly with inflow mitigation associated with private clear water connections and manhole rehabilitation. Indianapolis CMOM Program Report /20/2004

12 The city has conducted or initiated a number of programs to reduce inflow and infiltration (I/I). These programs include: Sanitary Sewer Rehab: Both DPW Engineering and United Water conduct sanitary sewer rehabilitation activities in both the sanitary and combined sewer areas. DPW Engineering is generally responsible for large diameter rehabilitation projects. United Water corrective activities include minor and major maintenance activities and minor capital improvement targets for structural rehab; sanitary, combined and storm mainline rehab; manhole adjustments; and storm water ditching. For more information, see Section 5.3 of this report. Leak Busters/Grease Busters: The city has recently reinstituted this committee to address I/I and grease blockage conditions that can lead to sanitary sewer overflows. Participants include staff from DPW Engineering, Operations and Customer Service; Marion County Health Department, the Department of Metropolitan Development; and United Water. Goals include addressing I/I mitigation and enforcement; SSO response and reporting; grease blockages; and illegal connections. Through Leak Busters/Grease Busters the city hopes to achieve: 1. Reduced sewer backups into residential, commercial, and industrial establishments 2. Reduced SSOs from the sewer collection system 3. Reduced financial risks associated with overflows and primary effluent overflows at the AWT plants 4. Reduction in costs for capital improvement projects associated with the sanitary sewer collection system and AWT plants 5. Reduced AWT processing costs Manhole Inspections: Through the Leak Busters program, the city is expanding its manhole inspection and assessment initiatives. DPW and United Water are developing protocols and training additional staff to perform manhole inspections, conduct assessments, and take corrective action. The goal is to reduce inflow and infiltration at manholes. Smoke and Dye Testing: The city s current smoke and dye testing program keeps two engineering consultant firms under contract to assist in investigations of neighborhoods experiencing I/I problems. The Leak Busters program will add training for DPW Operations staff in smoke and dye testing techniques. The city s goal is to train two or three Leak Buster crews to investigate I/I problems as necessary. An annual plan is being developed to coordinate additional efforts between DPW Engineering, Operations and United Water. Correct Connect: The Correct Connect program is being developed to educate residents about the problems caused by illegal connections and teach them how to become compliant with existing ordinances. Through the program, residents and partner organizations will learn the benefits of disconnecting their illegal connections and be given the tools and/or resources needed to redesign their existing connections. The program will provide several ways for the public to get involved, including self-correction, disconnection assistance, volunteer opportunities and neighborhood disconnection events. An educational video, brochures and partnerships with local hardware stores are planned as part of this campaign. Basin Master Plan/SSESs: As described earlier in Section , the city conducted a number of SSES studies in the 1990s in sanitary sewer neighborhoods. These were compiled into a Basin Master plan in The Basin Master Plan is used in capital improvement planning to prioritize and address I/I issues in sanitary sewer neighborhoods. Indianapolis CMOM Program Report /20/2004

13 Private I/I Removal Project: Private sources of inflow and infiltration have been identified as major problems in a number of cities. Indianapolis initiated a study in 1998 (Private Inflow and Infiltration Pilot Project) to evaluate the significance of this issue. Finding and fixing sewer defects on private property has been found beneficial in other communities, including Fort Wayne and Louisville. The primary goal of the pilot project was to find and fix sewer defects to sanitary sewers on private property and quantify the amount of clear water removed from the system. The secondary goal was to develop a mechanism to partner with homeowners to fix the defects with public funds. A pilot study in one neighborhood (Windsong at Geist Sewer Evaluation) was established to determine the causes of overflows at lift stations as well as sewer backups into homes. Many sump pump connections were identified; 16 percent of the 200 homes inspected had defects. Fixing the defects was found to be a cost-effective use of public funds at the Windsong site New Sewer Construction Design Standards Both the Department of Metropolitan Development (DMD) and the Department of Public Works are involved in the permitting process for new sewer construction and sewer connections. Requirements and standards for the installation of new sewers, pumps and other appurtenances; rehabilitation and repair projects; and other related items are detailed and specified in: Indianapolis Sanitary District Standards for the Design and Construction of Sewers, May 1989, (included as Appendix 3-25). Great Lakes Upper Mississippi River Board of State and Provincial Public Health and Environmental Managers Recommended Standards for Wastewater Facilities. Health Education Services, Albany, N.Y. (Also known as 10-States Standards ) Applicable state requirements for sewer main extensions under 327 IAC 3. A guidance document is also being developed for the proper capping of abandoned lateral sewers (Appendix Abandoning Building Sewers (Laterals) Guidance Document). Standards Update: The city s current design standards were written in 1989 to set administrative and technical requirements for the construction of sanitary sewers within the City of Indianapolis Sanitary District. Since written, numerous new technologies and products have become available that are not reflected in the current document. Also, many referenced specifications contained within the standards are outdated and obsolete. A New Products Committee processes requests to use new products or technologies not included in the standards. The city has initiated a project to update the existing standards to: 1) reflect new technologies and products, 2) comply with new IDEM requirements, 3) develop sufficient requirements to ensure the adequacy of the Indianapolis sanitary system, and 4) be easier to understand and more user friendly than the current standards manual. The Board of Public Works must adopt the Standards prior to implementation. The implementation phase will include numerous training and outreach meetings for both internal and external organizations Private Development Residential Activities: Homeowners are required to obtain permits and/or approvals for: Indianapolis CMOM Program Report /20/2004

14 Construction, placement or relocation of new or existing structures Interior or exterior addition, alteration, structural modification or remodel of an existing structure Cutting a city curb to gain access to a street or road Attachment to a city sewer line Conducting any activity, using or excavating in the city's right-of-way Demolition, wrecking, or removal of a structure Commercial, Industrial, and Multi-family Owners and Tenants: The owner or long-term lessee working on a structure other than a one- or two-family structure, is required to obtain permits and/or approvals for: Construction, placement or relocation of new or existing structures An interior or exterior addition, alteration, remodel, structural modification, change of use, or change of occupancy Site changes including but not limited to parking, landscaping, storm water drainage, and in some districts exterior appearance Installation of a new sign, or alteration or relocation of an existing sign Cutting a city curb to gain access to a street or road Attachment to a city sewer line Conducting any activity, using or excavating in the city's right of way. City right-of-way is generally all streets and sidewalks Demolition, wrecking or removal of a structure Sewer Construction Permits: The city processes two types of sewer permits for private developments: Sewer construction permits to allow extension of sewer mains, such as for a new subdivision or development. Sewer capacity is evaluated for all sewer construction permits. Sewer lateral permits to allow connections to the sewer main, such as for a house built within a subdivision. Sewer capacity is re-evaluated if the permit involves a commercial building. The process for sewer construction permits involves the following general steps: 1. Application. Application received by DMD and fee collected 2. Capacity Review. Infrastructure Plan Review Submittal Form, project design, project plans and required legal documents are reviewed by DMD for: Type of development to be served and its projected average daily flow, peak flow, and infiltration/inflow. DMD will verify proposed capacity, depth and flow. Sewer lines that are to be extended must have capacity and grade equal to existing sewers. Sewers also must be adequately sized for the contiguous services area, including unsewered and undeveloped areas capable of connection to the sewer. Location and size of receiving sewer downstream of proposed connection point. When there are known capacity problems with affected downstream sewers, DMD contacts DPW Engineering to conduct further review. The DPW review may involve: - Review of existing interceptor flow data - If there is no existing flow data available, the city may require the applicant to install monitors and provide current flow data - If flow data indicate capacity problems, the city may deny the connection or require that the applicant connect at another point in the sewer system Indianapolis CMOM Program Report /20/2004

15 Existence of a lift station downstream. DPW will review to determine whether upgrades to the lift station are necessary. DPW s review may involve pump down tests, flow monitoring, site inspections and other means to evaluate lift station capacity. If there are capacity concerns, the city may require that the applicant upgrade a lift station and/or enter into an operation and maintenance agreement for the lift station. 3. Technical review, approval and inspection. If there are no capacity concerns and any issues referred to DPW have been resolved, DMD will prepare a Wasteload Allocation Letter and forward it to IDEM. Consulting engineers under contract to the city will review plans for commercial and subdivision developments. Three engineering consultants are selected by the city each year through a Request for Qualifications process. The developer pays the fee for the technical review. For an additional fee, accelerated reviews are available on a limited basis. The consulting engineers will: Conduct a technical review of proposed sanitary sewers Confirm compliance with applicable design and construction standards If satisfactory, the city grants formal approval to the project and a sewer service agreement is executed. The permitting process is defined by its Standard Operating Procedures (Appendix 3-27). The end-of-year 2003 report for permitting summarizes permitting activities throughout the year, including sewer connections and construction (Appendix 3-28). Permitting information is available to the public at the DMD permitting office and through an extensive Web site. 604 N. Sherman Drive Indianapolis, Indiana Telephone: ; Fax Inspection: Inspection of private development projects (such as new subdivisions) is accomplished through professional service agreements with engineering consulting firms. (See Appendix 3-29 for an example of such an agreement). Each year, the city selects three or four engineering consultants through a Request for Qualifications process. A developer is required to enter into an agreement with one of the selected engineering firms, with fees set in advance by the city. This arrangement makes the developer responsible for the cost of inspection. The city retains the authority to set the standards to ensure competent inspection by a registered professional engineer. Inspectors work to prevent future infiltration/inflow by ensuring that: Pipes are properly connected and sealed Manholes are constructed properly No sump pumps or roof drains are connected to the sanitary sewer A list of sanitary and storm water sewers constructed within private developments during year 2003 is provided (Appendix 3-30). Code Compliance personnel are responsible for physically inspecting any sewer or lateral activities prior to the owner backfilling the excavation. The city s staff is able to respond within 4 hours of a request for inspection (during business hours). A Code Compliance Division within DMD provides the following inspection services to the public: Indianapolis CMOM Program Report /20/2004

16 Zoning Inspections - Inspections for compliance with land use and development standards of the City of Indianapolis Zoning Ordinances. Building Inspections - Inspections of residential and commercial construction for compliance with local and national building codes. Right Of Way Inspections - Inspections of all permitted work in the public ROW. This includes the inspection of all sanitary sewer connections to ensure they comply with the prohibition against clear water discharges. Appendix 3-31 provides a sample letter of violation for an illegal connection of a storm sewer to the sanitary sewer system. Private Development - Review plans for all commercial and residential development and inspect for compliance to City of Indianapolis Infrastructure Standards. Organizational charts for the Division of Compliance and its Permitting, Inspection and Information Services are shown in Appendix Planned Improvements: Among the improvements planned by the city in coming years are the following: Improve I/I enforcement program Improve tracking of permit connections and capital project benefits Improve tracking of reductions and additions to sewer system Continue to improve documentation of the permitting process Develop software tools to improve tracking, coordination and communication Additional Information: The following items describe various flowcharts, forms, and agreements in use by the city relating to permitting activities. Sanitary Sewer Construction Permit Information Summary Flowchart. City personnel use this flowchart to summarize the permitting process. Its primary focus is large commercial or subdivision developments. Included are permit submittal, permit triage, plan review, approval of final construction plans, etc. (Appendix 3-33) Flowchart Details (Steps 1 6). Permitting project managers refer to these flowchart details when evaluating proposed private development applications. (Appendix 3-34) Sanitary Sewer Lateral Connection Permit Application. Contractors initiate the sanitary sewer lateral connection permit process by completing and submitting this form. A city project manager must sign off on this application before a permit will be issued. (Appendix 3-35) Sanitary Lateral Flowchart. Permitting project managers use this flowchart to evaluate proposed sewer lateral connections for residential and commercial properties. (Appendix 3-36) Triage Checklist and Transmittal. Project managers use this internal document to prepare an initial review of the proposed development. Staff look at the overall impact of the proposed activity on the community. Included are concerns regarding flooding, sanitary problems, future sanitary sewer extensions (Barrett Law), other city projects, etc. (Appendix 3-37) Certificate: Sufficiency of Plan. This certificate is completed by a licensed professional engineer (generally the design engineer) at the time of project submittal. (Appendix 3-38) Capacity Certification/Allocation Letter. This letter is submitted to IDEM to verify capacity for any project that requires the issuance of a 330 IAC 3.1 Construction Permit from IDEM. (Appendix 3-39) Maintenance Bond. The Maintenance Bond is provided to the city by the licensed general contractor actually installing the infrastructure that will eventually become the Indianapolis CMOM Program Report /20/2004

17 city s responsibility. It provides a means for the city to correct deficiencies. (Appendix 3-40) Agreement for Construction of Sanitary Sewer Under Private Contract. This agreement is between the developer and the city to ensure that the new sewers are properly constructed and installed. Included is a maintenance bond and performance surety. The plan review process ensures compliance with the city s Sanitary Standards. (Appendix 3-41) Agreement for Construction of Sanitary Sewer Under Private Contract (15 Year Law I.C ). This agreement is for situations where the city has required the developer to oversize the proposed sanitary sewer. This will ensure sufficient capacity for future local development in that sewershed. The developer can recoup the extra cost through the 15-year law process. (Appendix 3-42) Sanitary Sewer Project Contractor s Affidavit and Inspecting Engineer s Certificate of Completion and Compliance. This certificate is completed by the licensed general contractor and the professional engineer under contract to inspect the work. (Appendix 3-43) Sewer Service Agreement. This agreement (contract) is between a property owner and the city. It establishes the responsibilities of both parties.

The city maintains a library of these connection records for future use. (Appendix 3-44) Hints for Lateral Contractor Selection. This document is provided to property owners who will be connecting to the public sanitary sewers. (Appendix 3-45) Public Development New and/or Rehabilitated Sewers: New or rehabilitated sewers required for public developments, such as Barrett Law or CSO control projects, also undergo a capacity review and must meet the same design standards as private developments. Procedures and specifications for inspecting and testing the installation of new publicly-developed sewers, pumps, and other appurtenances and for rehabilitation and repair projects are clearly established (see city s website: New sewers installed by the city s collection system contractor, United Water, are inspected by city Contract Compliance personnel. Inspection of Publicly-Developed or Rehabilitated Sewers: All public capital improvement projects are inspected by contracted engineering consultants. Engineering consultants are selected through a Request for Qualifications (RFQ) process (www2.indygov.org/rfq/logincontroller). Notices are posted at the city s Web page and are sent directly to consultants. An example of an RFQ request for a single project is shown below: Table 3.8 Example RFQ Item Listing Item No. 6 Contract: S.C.A.D.A. System Design Contract Number: LS A Project Type: Sanitary / Lift Stations Service Type: Design Contact (Planner): Bill Grout, Indianapolis CMOM Program Report /20/2004

18 Funding: Estimated Cost: $800,000 State Revolving Fund Schedule: Summer 2004 DPW is seeking a professional consultant with prior I&C design experience to design the upgrades for the city's proposed wastewater conveyance Supervisory Control and Data Acquisition (SCADA) system. The design will be based on recommendations from an ongoing study evaluating the city's needs. The selected consultant must demonstrate SCADA design experience using radio and cellular communications systems. The selected consultant must also be familiar with the city's IT infrastructure and the technology used by the County's Metropolitan Emergency Communications Agency. Once the consultant is selected, the city s project manager negotiates a contract with the consultant. The contract is reviewed by DPW management and the city s Corporation Counsel for consistency and legal acceptability. The contract is then presented to the Board of Public Works for approval. Inspection consultants are required to utilize DPW s manuals, specifications, procedures and policy documents as posted on the Web page at Out-of-County Requests It is the city s current policy to deny requests for new sewer service from locations outside of Marion County. All out-of-county requests are sent to the Office of Corporation Counsel. Since the late 1990s, the city has: Denied multiple requests to connect to the upper end of Belmont Interceptor. Opposed expansion of Tri-County Conservancy District due to potential impacts on the Bridgeport Interceptor Denied multiple connection requests from Hendricks County Denied multiple requests from Hancock County, including requiring developments falling in both counties to split service Prior to the late 1990s, the city provided sewer service for developments outside Marion County on a case-by-case basis. See sewer service agreements referenced earlier in Section Planning Sanitary Sewer Master Plan The city contracted with HNTB Corporation in January 2000 to prepare a sanitary sewer master plan for interceptors in West Marion County. The contract was expanded in October 2002 to include the remainder of the sanitary sewer area. The Sanitary Sewer Master Plan is anticipated to be completed by the end of The Sanitary Sewer Master Plan was initiated to assess current and future sanitary sewer interceptor needs in Marion County. It contains information useful for further development of relief sewers needed for current and future growth needs and to prevent unexpected disruption of sanitary sewer services. The scope of work included: Identifying and delineating major interceptor service areas Analyzing existing interceptor sewer capacity Estimating future flows from unsewered and undeveloped areas Indianapolis CMOM Program Report /20/2004

19 Identifying interceptor needs (both current & future) Evaluating alternatives to address specific needs Recommending a plan to provide adequate sanitary sewer service for all of Marion County for both current and future build-out conditions The methodology used to develop the plan included: Review of maps, sewer system data, as-built drawings Review of rainfall and sewer system flow data Review of population projections and DMD Comprehensive Land Use Plan Reports Review of water usage data from Indianapolis Water and Town of Speedway Continued expansion of the sewer system hydraulic model that was originally developed for the combined system into the separate sewer area Long-Term Control Plan In , the City of Indianapolis prepared a Long-Term Control Plan Report and Water Quality Improvement Report (LTCP) to address the long-standing problems that combined sewer overflows have caused, and to fulfill state and federal requirements for CSO communities. The city submitted its proposed LTCP to IDEM and U.S. EPA in April The LTCP is designed to improve water quality in Marion County and modernize the city s sewer system to 21st century standards. During the past several years, the city and a team of consultants have conducted extensive studies, modeling and characterization of Marion County s sewer system and streams affected by combined sewer overflows. These studies have demonstrated that many sources of pollution affect water quality in Marion County. These sources include CSOs, stormwater runoff, failing septic systems, and upstream pollution. Although the CSO long-term control plan is required to address only the combined sewer overflow problem, the city is considering other factors as part of a watershed-based strategy for improving water quality. Since submitting the plan to U.S. EPA and IDEM in 2001, the city has been working cooperatively with the regulatory agencies to develop a final, approved plan. In the meantime, the city has moved forward with numerous early action projects to reduce combined sewer overflows throughout the community. These projects include: Real-time control projects to reduce overflows at Ellenberger Park, Brookside Park, Howe Middle School, IUPUI, White River State Park and elsewhere Consolidation of Pogues Run outfalls 034 and 035 to reroute sewage overflows away from Indianapolis Public Schools campuses Inflatable dams to reduce overflows on Fall Creek near 32nd & 34th Street Sewer separation projects to eliminate outfalls affecting Forest Manor Park, the Municipal Gardens area, State Ditch, Lick Creek and portions of Bean Creek A 3-million gallon overflow storage and primary treatment tank on the east bank of the White River to reduce overflows affecting White River State Park and the IUPUI campus Expansions and upgrades to the city s advanced wastewater treatment plants to improve their capacity to manage wet-weather flows Indianapolis CMOM Program Report /20/2004

20 City of Indianapolis; Combined Sewer Overflow Long Term Control Plan and Water Quality Improvement Report; April 2001; Prepared by Camp Dresser & McKee Inc., Greeley & Hansen Engineers, Crowe Chizek, Perras & Associates (Appendix 2-6) Barrett Law Master Plan The Barrett Law (IC , Barrett Law Funding for Municipal Sewers, Appendix 3-46) is a state program for the design and construction of infrastructure, with the costs being shared by the property owners whose properties benefit from the improvement. Since the 1960s, the city has continuously used Barrett Law procedures for the installation of sanitary sewers. Projects are identified and prioritized in the city s Barrett Law Master Plan (Appendix 3-47). Costs are shared through an assessment, which is attached to a property upon completion of the infrastructure project. To keep assessments affordable, the city has historically contributed city funds to many Barrett Law projects. The city attempts to keep the assessment fees as low as possible while meeting all construction standards, thus maximizing the number of unsewered homes that can be converted to sewer service. In 2001, the state Barrett Law statute was amended to allow for more flexibility in paying Barrett Law assessments. Prior to 2001, payments were either a lump sum following final acceptance of the project or annual payments over a 10-year period. Property owners now have the option of a lump sum; annual payments over 10, 20 or 30 years; or monthly payments spread out over 10, 20 or 30 years. The interest rate prior to 2001 was established by the Board of Public Works at 7 percent. The Board's policy is to now pass through the interest rate the city receives through the State Revolving Loan Fund (SRF), which is currently just under 4 percent. Appendix 3-48 provides a Barrett Law Projects Summary for Stormwater Master Plan The city s Stormwater Master Plan, including the Capital Improvement Program (CIP) that lists stormwater-related projects scheduled through 2007, is available online at www6.indygov.org/dpw/stormwater/index.htm. The Stormwater Master Plan was developed based upon drainage complaints related to water quality, poor drainage, flooding, stream protection, and other environmental impacts. Through the master planning process, the city investigated and prioritized the complaints, incorporating them into the CIP, if warranted. The master plan report provides maps of the project locations, lists of CIP projects, and project information sheets detailing specific information on each project. The 2003 Annual Accounting Report summarizes stormwater-related budget and activities for year 2003 (Appendix 3-49). Appendix 3-50 lists the storm water Best Management Practices projects authorized by the Department of Metropolitan Development during A list of stormwater projects completed to date under Storm Water Utilities Funding is also provided (Appendix 3-51). The Indianapolis Stormwater Design and Construction Specifications Manual provides engineering standards for proper stormwater management for engineers, builders, contractors, land planners, and property owners contemplating some form of land alteration within the city s jurisdiction. In addition, the city may enter into inter-local agreements to extend jurisdiction of the Chapter 10½ Stormwater Management Ordinance and the Manual to excluded cities within Marion County. Included are departmental policies relating to stormwater management and flood control, submittal requirements, procedures for issuing a stormwater permit, and procedures for inspection, testing, Indianapolis CMOM Program Report /20/2004

Ogden Environmental & Energy Services, consultant to the city. (Appendix 3-52) City of Indianapolis, Department of Public Works Board, July 25, 2001, Amendments to Chapters 100 and 700 Drainage Design Standards and Specification Manual. (www6.indygov.org/dpw/stormwater/amend_chp100_chp700.pdf) The Indiana Drainage Handbook is an excellent reference for engineers, contractors, and developers. It is available at Capital Improvement Planning A five-year Capital Improvement Program (CIP) is prepared annually by DPW Engineering and submitted to the City Council for review and approval. The CIP reflects the anticipated capital improvements that will occur within the city during the specified year and the following four years. Projects included in the CIP are drawn from a number of sources, including the following: Basin Master Plan for replacement/repair of neighborhood sewers Sanitary Sewer Master Plan for interceptor needs Proposed Long-Term Control Plan for CSO control Barrett Law Master Plan for extensions of sewers into previously developed, unsewered areas Stormwater Master Plan for flood control, drainage and stormwater quality improvement Citizen complaints DPW Engineering s goal is to develop and implement a capital improvement program for the city s wastewater treatment, stormwater and sanitary collection systems that provides for the efficient and effective collection, conveyance and treatment of wastewater and storm water. The public plays an important role in identifying needed projects and in prioritizing the expenditure of public dollars. The CIP is considered a fluid document that is closely and continuously monitored and updated to reflect current needs and potential changing conditions. Included in the CIP is the following information: A summary page showing each project category and the corresponding investment anticipated for each category. Funding levels by revenue source (drainage and sanitary). Charts summarizing the amount of investment in each area of infrastructure (drainage and sanitary) A five-year listing of the Capital Improvement Program, including the current year and the following four years. The CIP is managed by DPW s environmental engineering staff, which includes 14 environmental, mechanical, electrical and civil engineers. City engineers are supplemented by highly trained program management and engineering teams, known as the Indianapolis Clean Indianapolis CMOM Program Report /20/2004

22 Stream Team for CSOs and the Stormwater Program Manager (DLZ). Many other professional engineering consulting firms provide the city with planning, design and construction-related services for the CIP program. A detailed report is included as Appendix 3-53, which summarizes the capital improvement projects for each project type (CSO, Lift Stations, Sanitary and Combined Sewer & Manhole Rehabilitation, Siphon Rehabilitation, Sanitary or Combined Sewer Studies). Appendix 3-54 is an example of the construction monthly reports that contractors must submit to the Department of Public Works for progress tracking. 3.3 Overflow Management Reporting Requirements The NPDES permits for the Belmont and Southport AWT plants detail the reporting requirements related to sanitary sewer and combined sewer overflows. SSO and Dry-Weather CSO Reporting: The city must verbally notify IDEM of all sanitary sewer overflows (SSOs) and dry-weather CSOs within 24 hours from the time Indianapolis becomes aware of the overflow. This is followed by written notice to IDEM within five days. Written notice must include the cause of the overflow and its duration, date and time of the overflow, and steps taken or planned to reduce and eliminate its recurrence. Discharges of pollutants that enter the waters of the State that result or may result in death, acute injury, or illness to any humans, animals or aquatic life must be reported within two hours of the time Indianapolis becomes aware of their occurrence. Section details United Water s overflow reporting procedures. Wet-Weather CSO Reporting: The city must report semiannually to IDEM the wet weather CSO volumes and discharges generated by the hydraulics model of its combined sewer collection system. The city also continuously monitors the volume and duration of CSO discharges at 19 locations and reports the results monthly to IDEM. Finally, the city is required to report CSO activation information monthly to IDEM Overflow Procedures All systems are subject to failures and malfunctions. Through an integrated and comprehensive CMOM Program, the city and United Water seek to reduce collection system malfunctions and prevent overflow occurrences. Malfunctions may be caused by blockages, equipment failure, power failures and other factors. The city tracks the cause and location of each sanitary sewer overflow and dry weather CSO and performs trend analysis on the data. Maps are prepared showing the location of overflows so that trends can be identified and corrective action undertaken (Appendices 3-55, 3-56, 3-57, 3-58 and 3-59). Overflow response procedures are documented in Section 4.3 (Overflow Response Operations). The city pays close attention to lift station maintenance and operations in order to minimize overflows at those locations. An aggressive lift station overflow reduction program reduced lift station overflows from 58 in 2002 to 11 in This reduction occurred despite historic rainfall and flooding events in July and September The city also is evaluating its grease enforcement and I/I reduction programs, as noted earlier in Section Indianapolis CMOM Program Report /20/2004

23 3.3.3 Constructed SSO Elimination Projects The Indianapolis sanitary sewer system had 16 constructed SSOs in the 1980s. Since then, the city has implemented a number of capital improvement projects to eliminate the constructed SSOs. The city has undertaken several projects to eliminate the three remaining SSOs from the system: Lift Station 402 Upgrade: The completion of upgrades to Lift Station 402 is necessary so that Lift Stations 404 and 405 may be eliminated and flow from Lift Station 403 may be rerouted. This project involves increasing capacity to handle additional wastewater flow from LS 403. Lift Station 402 upgrades will include the installation of an additional pump and accompanying controls to accommodate an approximate flow increase of 3,000 gpm, increasing LS 402 s capacity to 11,000 gpm. Lift Station 403 Replacement: This project will involve increasing the capacity of the station to handle additional wastewater flow. Relocation of the station is necessary so that the existing station may remain in operation during the installation of the new station. The upgraded station will include a new pump station structure and upgraded equipment with increased capacity necessary to accommodate flows exceeding the 3,100 gpm design flow. In order to reroute flows from LS 403 to the upper end of the East Marion County Regional Interceptor Sewer, a 16 forcemain will be installed between LS 403 and LS 402. Lift Stations 404 and 405 Elimination: This project will eliminate Lift Stations 404 and 405 through the installation of gravity sewer from Lift Station 405 to the relocated Lift Station 403. The new conveyance pipeline to LS 403 would be sized to convey all flows collected upstream, thereby eliminating sewage overflows at SSO 124. LS 403 Basin I/I Reduction: The I/I Reduction in LS 403 Basin project will rehabilitate or replace portions of gravity sewer pipes located throughout the collection system feeding into LS 403. The majority of the sewer pipelines and manholes in the basin are reading the end of their design life and need to be rehabilitated. The scope of this project will include identifying those manholes and pipelines that contain structural defects and repairing or replacing these components to reduce wet weather I/I and restore the structural integrity of the system. Together, the above four projects will eliminate SSOs 124 and 105 on the city s east side. SSO 113: The city is currently reviewing the findings of a study on the causes of overflows at SSO 113. The project is expected to involve correcting sewer system defects found during manhole inspections and smoke testing, improving Lift Station 115 s capacity to manage both current and future flows, and completing necessary upgrades to the Bridgeport interceptor. In addition, the city has re-instituted a Leak Buster/Grease Buster program to reduce I/I and blockages that cause sanitary sewer overflows in the collection system. This program was described earlier in Section Training Programs General City of Indianapolis Training: The city s Division of Human Resources has a Training and Development Section, whose mission is to be responsive to the City of Indianapolis s training needs by providing quality innovative and cost efficient instruction, which fosters the Indianapolis CMOM Program Report /20/2004

24 professional growth of all city employees. The division operates an Intranet Web site that provides city employees with information on course schedules, descriptions, and registration; continuing education resources; and articles regarding training. Training is offered to city employees on a wide variety of topics, including management skills and techniques, procurement, contract management, stress management, and basic and advanced software skills. DPW Training and Development Center: DPW operates its own training center to provide specialized training in skills needed by public works employees. The center s goals are to provide quality training with an emphasis on safety, to offer practical classes that help students excel at their jobs, and to have a professional staff that is helpful, courteous and respectful to all customers. The center also strives to be flexible in scheduling classes so as to incur minimal impact on daily work schedules. Courses are available on a wide variety of topics, including light equipment and heavy equipment operations, safety, hazardous materials, anti-terrorism awareness, computer skills, and general policies and procedures. DPW Engineering: DPW Engineering staff belong to a number of professional associations and attend conferences, workshops and relevant short courses to stay up-to-date on the latest technologies and practices. Outside experts also offer lunch-time seminars on various topics. Additional workshops are held at project sites to review key components of the project along with ways to improve future design and project management. United Water Training: United Water s Apprenticeship Program provides employees with opportunities to learn skilled trades such as electrical, electromechanical, HVAC and instrumentation. United Water also offers an Employee Development Training Program that leads to certifications and licenses in the following areas: Collections Operator Certification and the Indiana Municipal Operator s license in classes I, II, III and IV. Most certification classes are taught on-site, eliminating travel and registration hassles. A maintenance training program offers classes in electro-mechanics, basic industrial electricity, motor controls and lift station techniques. United Water s technical training curricula are described further below. United Water reports on training activities in its monthly reports to the city. Appendix 3-60 includes example training presentations for combined space entry, lockout/tagout, emergency response planning, and hazardous communications Technical Training Training for Sewer Condition Evaluation (PACP): DPW has initiated a program to provide a consistent method of evaluating videotapes of sewers from closed-circuit televising. The standardization is through a national program known as Pipeline Assessment Certification Program (PACP), which is administered by the North American Sewer Service Contractor s Organization (NASSCO, NASSCO is dedicated to the establishment of improved procedures and standards for all phases of sewer system rehabilitation. PACP is a method of training and certifying closed circuit television (CCTV) operators, engineers and other industry-related people to recognize, assess and report an observation in a pipe in a specific way. Assessing, recognizing and reporting using standardized criteria allows for accurate, reliable information to be generated, and then used. With proper training, individuals will both recognize the difference between cracks, fractures and other defects so they can be reported using standard criteria and verbiage, or codes. This provides Indianapolis CMOM Program Report /20/2004

25 more accurate and reliable information and a benchmark for the city in assessment of its sewer infrastructure. United Water Training: United Water has developed specialized curricula for employees responsible for operating and maintaining the collection system.

United Water supplements its full-time staff with contractors for a variety of tasks performed on an as-needed basis. 3.7 Information Management Policies and Tracking Systems Indianapolis was one of the first large cities in the country to invest in geographic information system technologies to manage and track its critical infrastructure. This investment has given both city administrators and field staff a powerful tool for planning, design, emergency response and other critical tasks. Several city and county departments work together to maintain geospatial information about the city s sewer systems: City of Indianapolis and Marion County Geographic Information System (GIS) Engineering Division (DPW) Operations Division (DPW) Indianapolis CMOM Program Report /20/2004

30 Permits Division (DMD) The Indianapolis/Marion County GIS department coordinates a wide range of GIS uses, including sewer system mapping and GIS updates to the sewer systems. The GIS department provides leadership and directs policy decisions with respect to software and authorized users Infrastructure Mapping and GIS Historically, Indianapolis maintained sewer mapping information and records using paper maps. The DMD Permits Division is responsible for gathering and maintaining consistent records for private development. The DPW Engineering Division has been responsible for records related to public improvements. A complete set of these maps are kept at the Permits Division at 604 N. Sherman Drive. In 1986, the Indianapolis Mapping and Geographic Infrastructure System (IMAGIS) consortium was created to develop GIS infrastructure for Marion County. The GIS was tied into a maintenance management system (Hansen/IMS) during the early 1990s. Hansen/IMS (described in Section 3.7.3) continues to be used by the city and United Water for maintenance management. The Department of Public Works maintains comprehensive Sanitary Sewer GIS information for the majority of the facilities built prior to Additionally, they maintain paper as-built drawings for new infrastructure built after All GIS data exist in ESRI s SDE format stored in an Oracle database on a SUN server. Analytical facility information exists in ORACLE in the Hansen Information Management System (IMS). A comprehensive Indianapolis Web site is maintained by the city ( Figure 3.2 Geographical Information System Home Page Indianapolis CMOM Program Report /20/2004

31 Data & Metadata: Maintenance of data and its associated metadata is one of the main responsibilities of the Indianapolis/Marion County GIS team. As an organization, the city and county have more than 200 layers of geographic information available, with many more layers available within specific city departments. A Web page is maintained to track and share information ( and to provide linked pages that make it easier to share data across departments. The following screen image depicts the Data and Metadata for sanitary sewers. Figure 3.3 Data and Metadata for Sanitary Sewers The GIS system is used by many people associated with and working on the city s wastewater collection system. Many engineers, planners, project managers, permit specialists, operation and maintenance personnel, inspectors, township coordinators, township administrators, and engineering consultants have ready access to the ARCVIEW/GIS system. In an effort to increase internal and external accessibility, and to decrease licensing costs, the GIS system is migrating from ArcVIEW 3.X to ArcGIS 8.0, and allowing Web-based access via ArcIMS. The figure below displays a typical screen image showing the sanitary and storm sewer layers in a residential neighborhood. Indianapolis CMOM Program Report /20/2004

34 Each shape file within the GIS system links to a comprehensive database that includes a wide variety of data. An attribute table for sanitary sewers includes asset tag numbers (generally upstream manhole number), diameter, materials, type, and other information. Figure 3.6 GIS Attribute Table of Sewer Segments Hansen/IMS The city has two computer maintenance management systems (CMMS) that it uses to manage the collection system and the AWT plants. Hansen information management system software is used primarily to maintain maintenance records for the collection system. Recently, the city has begun to move toward linking Hansen to the city s GIS interface. With the new GIS link, maintenance records for an asset such as a sewer pipe or manhole could be accessed by clicking on the GIS map showing that asset. The linkage between Hansen and GIS is about 90 percent complete. City staff are working to reconcile any discrepancies between the two systems. The city also recently completed a 1.5-year project to establish a master address database for GIS, Hansen, the Tidemark permitting system, and the city s Customer Relations Management Indianapolis CMOM Program Report /20/2004

35 systems. This project allows for better communication between the systems and the potential to link systems to each other in the future Wastewater SCADA System Project The city s existing pump station alarm system is out of date and not capable of providing the services Indianapolis will need in the coming years to manage the collection system. The city has begun planning and design for a new wastewater collection system SCADA system, which will have the capabilities and performance necessary for it to become the cornerstone management tool for the new wastewater collection system. The SCADA system will connect remote sites located throughout Marion County with a central facility. The remote sites will include pump stations, flow metering stations, rain gauge stations, diversion structures, and a variety of other water- and wastewater-related facilities. The new SCADA system central facility and remote sites will use programmable logic controller (PLC) and PC-based human-machine-interface (HMI) technology. Communication between the remote sites and the central facility will be primarily radio-based with selected use of leased lines. The remote sites are divided into three levels based upon the needed performance. Each type has different performance requirements and a different amount of transmitted information. Construction is expected to start in Information Tracking Systems and Reporting United Water maintains a record of preventive, predictive and routine tasks in its DataStreams 7i computerized maintenance management system, organized by the PM ID number. This information is used to generate quarterly reconciliation reports and monthly performance reports to the city. Information is transferred to the city s Hansen IMS system at the end of each month, as required. Example charts and data generated by these systems are provided in Sections 4 and 5 of this report. 3.8 Financing and Cost Analysis Rate Analysis The city completed a sewer use rate study in 2000 to identify funding requirements necessary to implement its overall wastewater capital improvement program. This program includes combined sewer overflow controls, improvements to existing advanced wastewater treatment facilities and pumping stations, sanitary sewer rehabilitation, construction of new sanitary sewers to ensure adequate capacity, implementation of the city s septic tank conversion program, and sanitary/storm sewer water quality projects. The rate study, prepared by Crowe Chizek and Company, LLC, showed Indianapolis current rates were among the lowest in the country, Midwest region, and State of Indiana. Sewer user rates had not been increased during the 20-plus years prior to the 2000 rate study. Due to increasing costs of operating existing facilities and needs to construct new facilities, the city implemented a 17.8% rate increase in Rates were increased for all customers (residential, industrial, commercial, contract, etc). This increase raised average monthly residential sewer user rates to $11.74 (for 7,000 gallons of water consumption). In addition to charges for water consumption, industrial and commercial customers pay additional surcharges for strength beyond that of normal sewage. Surcharges are applied for suspended Indianapolis CMOM Program Report /20/2004

36 solids, biochemical oxygen demand (BOD), and ammonia nitrogen. Surcharges for each are as follows: Suspended solids - $ per pound in excess of 300 milligrams per liter BOD - $ per pound in excess of 250 milligrams per liter Ammonia nitrogen - $ per pound in excess of 20 milligrams per liter The city continues to conduct rate analyses to assess the need for future rate increases Budget Process Beginning in April, city department heads, along with the offices of the Mayor and the City Controller, develop budgets for the next calendar year for divisions within their departments. State statute and Council ordinance require the city to adopt annual balanced budgets that is, revenues plus fund balance must equal or exceed appropriations. The major classification of appropriations is the character level, which corresponds to the Governmental Accounting Standards Board definition of object. The characters of expense are personal services, supplies, other goods and services, properties and equipment, and internal charges. Operating appropriations lapse at year-end unless they are encumbered. A purchase order is recognized as an encumbrance against available appropriations. Total appropriations for capital projects funded by bond issues are set within the bond resolution and do not expire at year-end. In July, the City Controller prepares budget ordinances that are introduced by the Mayor to the City-County Council at the first meeting in August. These ordinances are assigned to the appropriate Council Committee, which conducts public hearings during August and September. Prior to the last Council meeting in September, the budget levy is advertised twice in two newspapers. The Council may not pass a budget above the levy advertised. The Department of Local Government Finance reviews the budget before certifying the levy; a levy above the limits may be granted if the excess levy meets the state law requirements. The Tax Commissioners are required to certify the levies, tax rates and budgets by February 15th. During the year, the City-County Council may amend appropriations upon request by the Controller to transfer unencumbered appropriations from one character to another in the same fund. Additional appropriations requests are submitted to the Controller s office to determine if sufficient additional revenues or fund balance is available. Non-ordinance budget transfers occur as needed. Budgets are controlled at different levels depending on needs of each departments. DPW s regular operating budgets are controlled at the character level. After the close of the year, independent public accountants perform an audit. The Report of Independent Accountants stated that the financial statements for the City of Indianapolis, Indiana at December 31, 2001 showed fairly, in all material respects, that the financial position of the city, the results of operations, and the changes in financial position were in conformity with generally accepted accounting principles. The proposed 2004 City Budget is detailed on the city of Indianapolis s website at the following address: www6.indygov.org/controller/budget_2004/index.htm. Indianapolis CMOM Program Report /20/2004

37 3.8.3 Funding Sources Funding of CMOM-related activities is derived from a variety of sources including: sanitation general funds, state revolving loan funds, revenue bonds, general obligation funds, city cumulative funds, plant replacement funds, and stormwater utility revenue. The following paragraphs briefly detail each source. Sanitation General funds are collected from sanitary user fees. These funds can be used to maintain, upgrade and construct new sanitary facilities within the sanitary district. State Revolving Fund (SRF) monies are made available at a below-market interest rates to the city through the Indiana Department of Environmental Management and the State Budget Agency. The city pledges repayment of the borrowed SRF funds with sanitary user fees. SRF funds may be used to maintain and reconstruct sanitary facilities; address combined sewer overflow issues; and extend sewers for Barrett Law projects. Projects that extend sewers for projected development are not eligible for SRF funds. Additional details regarding the SRF program and the Indianapolis Bond Bank are available in Appendix Revenue Bond and General Obligation funds are derived from publicly issued debt for capital projects. Previously issued sanitation revenue and general obligation bonds pledged user fees to repay the bond debt service. Revenue and general obligation bonds have historically been used for large capital projects. City Cumulative funds are collected from property taxes. Cumulative funds can be used for purchasing easements or right of ways, to construct or improve city infrastructure or to retire general obligation bonds. Plant Replacement funds appear as a special appropriation by the City-County Council for capital projects at the Belmont and Southport Advanced Wastewater Treatment facilities. The fund is capped at $15 million, with $1.2 million dedicated to the fund on an annual basis. Stormwater Utility funds are generated from a fee placed upon all properties in Marion County. Residential properties pay a flat fee and non-residential properties pay based on the amount of impervious surface on their property, minus allowable credits for stormwater controls. Stormwater utility funds may be used only for expenditures related to the county s stormwater system. 3.9 Customer Service Complaint Management Mayor s Action Center Citizens with complaints or concerns may contact the city by calling or ing the Mayor s Action Center. Items that can be addressed through the Mayor s Action Center include trash or debris problems, chuckholes, basement backups, local flooding concerns, questions regarding construction activities, etc. Indianapolis CMOM Program Report /20/2004

38 Figure 3.7 IndyGov egov Center Webpage Citizen s calls are logged and tracked by a computer software program. Each issue referred to DPW is investigated by the appropriate Township Coordinator. The Township Coordinator determines if the issue is the city s responsibility and jurisdiction and then, if appropriate, initiates a work order using the Hansen/IMS system. Hansen/IMS forwards the work order and problem details to the appropriate service department (streets, solid waste, flood control, United Water, etc.). The supervisor can then determine needed equipment, spare parts, and assign operations and/or maintenance staff to correct the problem. Once the work is completed, the details are added to the Hansen/IMS system. Citizen Relationship Management System: Since its inception, the MAC has used Expert Advisor call center software and standard desktop computers to conduct business. While at the time the Expert Advisor system was state of the art, it is no longer being upgraded or supported and does not meet all current City of Indianapolis business needs. Late in 2002, the city released a Request for Proposal for consulting services to determine whether a Citizen Relationship Management (CRM) system is the appropriate replacement system to provide short- and longterm solutions. Early in 2003, the selected consultants conducted surveys of city employees and citizens. They evaluated all workflow and business processes and our current telephony and technological infrastructures. They determined the requirements for a new call center, including technical and business process changes. Indianapolis CMOM Program Report /20/2004
