• Town of Collingwood Drinking Water Quality Management System Policy

4. ANALYSIS

The attached update on operational activities in both the drinking water and wastewater systems provides a brief overview of the status of ongoing initiatives and capital projects, as well as some operational challenges that were overcome, between January and June 2021. Some highlights of the update report are provided below. Drinking Water System

• The drinking Water Treatment Plant (WTP) operated at up to 81% of its rated treatment capacity.

• The WTP operated at up to 83% of the available winter treatment plant capacity, assuming a maximum free chlorine residual of 2.2 mg/L entering the water distribution system. Staff have been reporting to Council separately on how the remaining capacity relates to the ability to service new developments and other municipalities until additional capacity is made available, which has led to an Interim Control Bylaw and a Land Use Planning Study, both of which are underway.

• There were no adverse water quality incidents in the drinking water system.

• Six (6) watermain breaks occurred and were repaired in the water distribution system.

• Hydrant painting Request for Quotation (RFQ) was issued and awarded in Spring/Summer 2021, with work expected to start in September 2021.

• Watermain leak detection RFQ was issued and awarded in Summer 2021, with work currently underway.

• One full membrane train was replaced in June 2021. Significant repairs were completed on other membrane filters at the same time as the train replacement.

• Structural repairs are required at the WTP in advance of the WTP expansion construction due to ongoing settlement issues. This work is moving ahead as a roster engineering assignment with construction tendering expected to occur later in 2021.

• The WTP expansion and upgrades engineering services Request for Proposal (RFP) was issued in May 2021 and awarded in July 2021; design is underway.

• The RFP for consulting services for assisting with procuring SCADA software and integrator services, as well as developing SCADA standards was issued and awarded in Spring 2021. The SCADA Software RFP was issued in August 2021 with a September 2021 closing date.

• Design of the Davey Bulk Water System replacement has been added to the scope of the SCADA Upgrade project. The current software for the bulk water system will not be compatible with new SCADA system software. Additional funding to for construction of the new bulk water system will be requested as part of the 2022 budget to allow this work to continue to proceed.

• Osler Bluff Booster Pumping Station (BPS) upgrades were completed in Spring 2021; the project is in warranty phase.

• Design for Carmichael Reservoir and BPS is underway. This project has seen delays during the design phase. Construction tendering is now expected to take place late in 2022.

Wastewater Treatment

PW2021-15 Environmental Services: 2021 Mid-Year Operations Update Page 3 of 3

• The Wastewater Treatment Plant (WWTP) operated at approximately 57% of its rated capacity.

• All wastewater effluent sampling results met the effluent quality compliance limits specified in the Environmental Compliance Approval for the WWTP.

• There were no wastewater treatment by-pass events.

• Repairs were completed on the bar screen in the headworks at the WWTP.

• Repairs were completed on a primary clarifier at the WWTP.

• Cleaning of mixers in Digester No. 1 was completed at the WWTP.

• The pump at the Tenth Line Sewage Pumping Station (SPS) was replaced.

• UV Transmittance monitors were installed at the WWTP to automatically adjust the UV dosing on the wastewater effluent.

• Engineering preparations were initiated and a RFQ was drafted for the cleanout and inspection of Digester No. 1. The RFQ was issued in August 2021 and work is expected to be completed in Fall 2021.

• The construction tender for the sludge pump replacement at the WWTP was issued and awarded; construction is expected to commence in September 2021.

• Variable Frequency Drives (VFDs) were installed on the WWTP influent pumps.

• Design for pump replacements at Paterson SPS is underway. The engineer’s review has identified extra scope for this project due to the National Fire Protection Association (NFPA) hazard rating for the site, resulting in some structural and mechanical modifications being required to separate the spaces in the building. Additional funding will be requested as part of the 2022 budget to allow this project to proceed

May 690,155 17,094 21,421

June 818,877 22,041 25,069

A comparison of the drinking water production rates to the total rated WTP capacity

(31,140 m3/day) indicates that the WTP was operating at 59 – 81% of its rated capacity during

the first half of 2021. Factoring in winter disinfection limitations, and assuming the maximum

desired free chlorine residual entering the water distribution system from the WTP is 2.2 mg/L,

the WTP was operating at 77 – 83% of its winter capacity (24,019 m3/day) from January through

April 2021.

Wastewater Treatment Rates

Between January and June 2021, the Collingwood Wastewater Treatment Plant treated

3,098,510 m3 of wastewater. The average day and total sewage treated for each month is

June 356,750 11,892

A comparison of the average day wastewater treatment rate to the rated treatment capacity

(24,548 m3/day) for the Collingwood WWTP indicates the plant operated at an average capacity

of approximately 57% in the first half of 2021. However, it should be noted that the rated

capacity for the WWTP is actually based on average day wastewater flows throughout the

course of a year, therefore a more accurate representation of the available WWTP treatment

capacity will presented at the end of 2021.

Raw, Treated and Distribution Water Quality Ontario Regulation 170/03 specifies the number of samples to be taken, the frequency of sampling and the actions to be taken if any sample results indicate adverse water quality. Schedule 10 of Ontario Regulation 170/03 requires weekly sampling and testing for E.Coli, Total Coliform and Heterotrophic Plate Count (HPC). Samples are collected weekly from raw and treated water at the Raymond A. Barker Ultrafiltration Plant and from several points throughout the distribution system. The samples are analyzed by an accredited laboratory. Sampling data for the period of January - June 2021 are presented in the tables below:
