1 DATE: January 16, 2018 REPORT NO. PW TO: FROM: Chair and Members Committee of the Whole Operations and Administration E. (Beth) Goodger, General Manager 1.0 TYPE OF REPORT CONSENT ITEM [ ] ITEM FOR CONSIDERATION [X] 2.0 TOPIC: Wastewater Pumping Station Analysis [Financial Impact - $138,980] (PW ) 3.0 RECOMMENDATION A. THAT Report No. PW entitled Wastewater Pumping Station Analysis BE RECEIVED; and B. THAT Council APPROVE the additional scope of work and associated cost to GM BluePlan Engineering Limited s Purchase Order (OS1241) as a noncompetitive award to be funded from Capital Accounts WW1612 and WW1613, pursuant to the City s Purchasing Policy, s.8.03 c, part (i). 4.0 PURPOSE The purpose of this report is to obtain Council approval to extend the scope of work for the Water, Wastewater and Stormwater Master Servicing Plan (hereafter referred to as MSP ) to include field analysis of the capacity and performance of the City of Brantford s nine (9) Wastewater Pumping Stations (hereafter referred to as WWPS ).

2 Date: January 16, 2018 Page BACKGROUND An update to the MSP is currently underway to determine the extent of municipal servicing required for growth expected within the new City limits to 2041 population projections, which will be identified as part of the Official Plan Update. The requirements and procurement process were described within the August 8, 2017 report titled Updates to the Transportation Master Plan and the Water, Wastewater, Stormwater Master Servicing Plan (PW ). Council approved the funding and single-source award to GM BluePlan Engineering Ltd. to undertake the work necessary to update the MSP. The scope of work included developing a preferred water, wastewater, and stormwater servicing strategic visions to: 1. Support existing infrastructure needs, and, 2. Evaluate the impacts of projected growth. The intent of the Wastewater Pumping Station Analysis is to complete the following field testing: draw down testing, which is a test of pump performance in the pumping station to confirm the capacity of each WWPS, wet well structural and mechanical inspection to verify the state of the existing equipment, and; forcemain transient analysis, which is a test of forcemain integrity under operating pump conditions to identify potential risk of asset failure. This additional performance related information will greatly improve the desktop analysis undertaken as part of the MSP as well as support several Public Works departments as it pertains to asset operation and maintenance and capacity allocation monitoring related to greenfield and infill growth. 6.0 CORPORATE POLICY CONTEXT This initiative would meet the goals of the City s Community Strategic Action Plan. In particular, the following goal is applicable: 6.1 Shaping our Future: Brantford s Community Strategic Plan Managed Growth & Environmental Leadership Water and Wastewater Review and implement the Water, Wastewater and Stormwater Master Servicing Plan in conjunction with the Official Plan taking into consideration both balance and fairness for all neighbourhoods. 7.0 INPUT FROM OTHER SOURCES Facilities and Asset Management, Continuous Improvement, Purchasing, Finance and Environmental Services staff were consulted in the development of this report.

3 Date: January 16, 2018 Page ANALYSIS Through the August 28, 2017 report number PW the City committed to complete an update to the 2014 MSP for water, wastewater and stormwater servicing to the year The scope of work to complete this included identifying a preferred wastewater, water, and stormwater servicing strategic vision to support existing infrastructure needs and impacts of projected growth. To identify the infrastructure needs and servicing costs, a hydraulic model based on design reports, current, and future population numbers is required. A variety of data sets are required to enhance the accuracy of the City s existing hydraulic model including wastewater flow monitoring and pumping station capacity analysis. Once integrated, the model can more accurately identify areas of potential capacity constraints and or availability in the collection system. Initially the model developed for early versions of the MSP consisted primarily of a desktop analysis, based on design and theoretical values with limited flow data however, this may not reflect existing field conditions. Over the past year the City has been collecting a variety of data sets including flow monitoring at key locations in the City to improve the accuracy of the model. Flow monitoring in the wastewater system will continue to be completed in order to improve model results and accuracy. Draw down testing and forcemain transient analysis provides a snapshot of the performance of each WWPS in current operating conditions. The results of the testing and analysis, along with flow monitoring data being collected within the sanitary network, is proposed to be used to calibrate the hydraulic model thereby making results more accurate and improving the City s ability to predict capacity demands and requirements to The results will provide information to help guide future capital upgrades to meet future growth demands. GM BluePlan Engineering Limited can efficiently complete this work under the scope of the MSP since: The team can concurrently complete the analysis with the work required for the MSP, The outcomes from the analysis can be fully integrated into the MSP analysis and recommendations, and There are economies of scale in having a single firm undertake the field work and desktop analysis It is therefore recommended that this work be completed under the 2041 Master Servicing Plan since the resulting information will be integral to the outcomes and recommendations of the Plan to support future growth and development in the City. Council approved the funding and single-source award of the MSP update to GM BluePlan Engineering Limited as per the recommendations in the August 28, 2017 Report PW through a non-competitive request. As per City

4 Date: January 16, 2018 Page 4 Purchasing policy (section 8.03 (c), (i)), Council approval is required for an extension to services awarded in a non-competitive process. Since this work is an extension to the services outlined in the original request, Council approval is required for an extension to the previous non-competitive award. If approved, a change order will be processed against the original purchase order issued for the Master Servicing Plan Update (OS1241) to allocate the budget required to complete the Wastewater Pumping Station Analysis. The analysis will be initiated upon Council approval with the testing starting in February to be completed in April 2018 for the findings to be analyzed and incorporated into the final 2041 Master Servicing Plan deliverable by June FINANCIAL IMPLICATIONS A detailed cost proposal to carry out the Wastewater Pumping Station Analysis was submitted by GM BluePlan Engineering Ltd. Staff determined the costs provided in the proposal are fair for the work specified. The provided cost to complete the work is $138,980 and Table 1 demonstrates that there are sufficient funds available in the project budget to complete this work. Due to efficiencies realized by undertaking the analysis in parallel with the MSP Update, Staff recommends that the 2016 approved project budgets (WW1612 and WW1613) be used to fund the Wastewater Pumping Station Analysis. Table 1 identifies the Council approved funding available in each of these project budgets and the funding remaining after a change order is applied to the original purchase order issued to GMBluePlan Engineering Ltd. Table 1 Wastewater Pumping Station Analysis Budget Capital Project Original Available Required Variance Wastewater Pumping Station Wetwell Inspection Program (WW1612) $90,000 $89,691 $77,300 ($12,391) Wastewater Pumping Station Draw Down Test & Transient Analysis (WW1613) $75,000 $75,000 $61,680 ($13,320) Totals $165,000 $164,691 $138,980 ($25,711)

5 Date: January 16, 2018 Page CONCLUSION As development continues to thrive in the City, it is essential to complete the proposed analysis of the WWPS infrastructure. Verification of the capacity and condition of the WWPSs will support efforts to prioritize capital upgrades to be identified in the Master Servicing Plan to meet ongoing and future growth. There are sufficient funds available in the project budgets for GM BluePlan Engineering Ltd. to undertake the Wastewater Pumping Station Analysis. Council approval of the additional assignment will enable the work to be completed by Q and the findings incorporated into their current assignment to complete the City s Master Servicing Plan Update.
