1 City of Compton Water Utility Division 205 S Willowbrook Ave, Compton, California (310) Fax (310) REQUEST FOR PROPOSALS SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA) SYSTEM WATER DESIGN PROJECT I. INTRODUCTION JUNE 2, 2014 The City of Compton Water Utility Division (CWUD) is soliciting proposals from qualified engineering consultants to provide professional engineering services to assess and design the upgrade/replacement of the existing Water Supervisory Control and Data Acquisition (SCADA) System for the CWUD. The scope of work, which is more specifically described in Attachment 1 to this Request for Proposals (RFP), includes performing a comprehensive water systems analysis, a communications path study, developing a preliminary design concept, and preparing plans, specifications and estimates (PSE) for City bidding. II. BACKGROUND The City of Compton is located in Los Angeles County, California. It delivers water services to more than 15,000 service connections through approximately 156 miles of water mains. The distribution system consists of a pipeline system, five (5) existing water tanks with a total storage capacity of million gallons, one (1) pressure zone and eight (8) operational ground water wells, with a ninth well to be constructed in the next 2 years. On average, about 80% of the system water is from the City s ground water wells. During periods of low demand, the storage tanks are filled for later use during peak day and peak hour consumption. The City obtains the balance of its supply from the Metropolitan Water District (MWD) through three (3) connections. The system also includes eight (8) interconnections with adjacent water systems and three (3) pressure monitoring stations. 1

5 ATTACHMENT 1 SCOPE OF WORK FOR REQUEST FOR PROPOSALS WATER SCADA SYSTEM DESIGN CITY OF COMPTON WATER UTILITY DIVISION Objective The City of Compton Water Utility Division (CWUD) is requesting proposals from qualified and interested consultants to provide professional engineering services to assess and design the upgrade/replacement of the existing SCADA system for its water system. The scope of work, stated below, will specifically detail the requirements of this RFP, including assessment of the existing water system, performing a communication pathway assessment, developing an overall SCADA system design complete with an implementation schedule and budget. Background The City of Compton is located in the Los Angeles County, California. The CWUD provides high quality water and service to nearly 80,000 residents and businesses. The CWUD has two water sources. It has a groundwater source comprising of eight (8) existing wells and one future well. It also has a long-term wholesale agreement with the Metropolitan Water District (MWD) to supply surface water to the City of Compton. CWUD taps into these two sources as needed to satisfy the water demands of its customers. The City also operates four above ground storage tanks on a single site in the south part of the City and one stand alone above ground storage tank in the north eastern part of the City. To meet water quality regulations, the City of Compton provides on-site disinfection of its groundwater source using 12.5% sodium-hypochlorite solution. Due to Compton s topography, the City only maintains one pressure zone. The following chart summarizes the facilities of the Compton water supply and distribution system.

This existing system is inadequate and needs to be replaced with a more robust SCADA system. CWUD wishes to obtain a plan that includes the design and technical specifications to construct a state-of-the-art SCADA system for its water system. Scope of Work The following are the specific tasks to be performed by the consultant: 1. Assess the existing water system to determine conditions and necessary water system hardware and appurtenances to be installed in anticipation of implementation of a SCADA system. The CWUD envisions installation of a PC based SCADA system with open architecture that is easy to operate, maintain, and expand. The consultant shall include evaluation of upgrading the City s current ClearScada software and at least two (2) different software packages for CWUD s consideration. The consultant shall recommend a proposed design and system that has all the necessary back-up and 2

7 redundant components to ensure reliable and accurate long-term performance of the system. CWUD will select a system that deems most appropriate for its needs. 2. Assess the radio communication pathway for the SCADA system. The consultant shall include evaluation of at least three (3) different communications systems for CWUD s consideration. The consultant shall recommend a proposed system that has all the necessary back-up and redundant components to ensure reliable and accurate long-term performance of the system. CWUD will select a system that deems most appropriate for its needs. 3. Design a comprehensive SCADA system which would allow for the monitoring, operation, and control of the water system. The parameters to be included: a. Operations of well pumps, boosters, MWD connection and set-points for each. b. Flow monitoring at wells, MWD connections, storage facilities, and strategic points within the distribution system. c. Water levels in the storage facilities and pressure within distribution system. d. Ability to monitor and record distribution system water quality parameters such as chlorine residual, ph, turbidity, and temperature. e. Addition of intrusion switches at all entry points for buildings and tanks (door and hatches). f. Communications pathway for the SCADA system. Deliverables CWUD expects the following minimum deliverables from the consultant: 1. A letter report detailing the results of their assessment of the existing system and a list of necessary water system hardware and appurtenances complete with technical specifications to be installed prior to the implementation of the SCADA project. 2. A letter report detailing the results of the communications pathway assessment (radio study) for the SCADA system. 3. A complete design of a comprehensive SCADA system with all its necessary components for a functioning system when completed. The design should include engineering plans, specifications, drawings, and installation details that would allow CWUD to seek public bid for the build phase of all hardware to be installed. PS&E should be provided for each location where modifications are necessary and where new equipment is required to be installed. 4. A complete and comprehensive cost proposal outlining completion of the following during the build phase of the project: completion of all associated SCADA programming (operating system, PLCs, etc.), verification of factory acceptance testing of control panels, commission of each site, training, final documentation and manuals. 3
