This project will upgrade four (4) existing ‘flow through’ sanitary wastewater pump stations located in Bay Ward to improve their operation and reliability. The flow through stations normally operate as a gravity sewer; however, they switch operation from a gravity sewer to a sanitary pump station once the downstream receiving sanitary trunk sewer is surcharged or overtaxed to prevent upstream basement flooding.
Improvements are required for upgrades for reliability and resiliency as the current configuration requires regular maintenance and manual operation. The proposed upgrades include installing new backup generators required for emergency situations, replacing existing pumps with two (2) new pumps (One Duty and One Standby/Backup), updating electrical and instrumentation to current standard requirements and other miscellaneous improvements.
Why: Due to the age, condition and level of operation and maintenance required for the existing infrastructure and the lack of redundancy from basement sewer backup protection, the City will be proceeding with the completion of the work required to improve the reliability of these pumping stations. The project will upgrade each station to have redundancy in pumping (duty/standby configuration), resiliency in instrumentation monitoring, power and controls to reduce the likelihood of having a failure that could result in flooding.
When: Starting over the summer of 2022 to be completed by summer 2023
