City of Toronto – Ashbridges Bay Treatment Plant Integrated Pumping Station

Ashbridges Bay Treatment Plant Integrated Pumping Station (IPS) 

Eramosa is currently working with Black & Veatch on a multi-year, multi-phase set of projects to develop a new Integrated Pumping Station (IPS) that will replace the current M&T pumping stations. These stations currently feed the Ashbridges Bay Wastewater Treatment Plant. 

The M&T pumping stations are nearing the end of their useful service life and are difficult to maintain. Under a pre-design project, also completed by Black & Veatch and Eramosa, several options for replacement were reviewed.

The final decision was to build a new pumping station at the ABTP site to replace the current M&T pumping stations as well as incorporate a new Wet Weather Flow (WWF) station. The WWF station will connect to the future Don River & Central Waterfront project, which includes a series of wet weather collection tunnels currently under design and construction. 

This work is also being undertaken by Black & Veatch and Eramosa. The design will include pump sets for each of the main interceptor sewer mains as well as the new WWF tunnel, with passive overflow and integral pump redundancy. Eramosa is developing the instrumentation & control and SCADA design including network architecture, instrument selection and development of the process control narrative. 

The project ties into the large Don River and Central Waterfront project currently underway with final completion estimated in 2025.
