Wastewater redesign

Xylem has been selected by the City of Toronto to supply customized equipment for a new integrated pumping station (IPS) – a critical component for the transport of wastewater. The project will replace two existing pumping stations, one operating since 1911 and the other since the early 1970s, both adjacent to the Ashbridges Bay Wastewater Treatment Plant.

The plant’s new IPS will include 14 Flygt A-C series dry pit pumps. These pumps are designed for low maintenance and operational costs, according to Xylem. Once operational, the IPS will move raw sewage from the underground sewer system into the treatment plant. In addition, the IPS will add wet weather flow pumping capability to pump collected CSOs from the new Don River and Central Waterfront tunnel system, to a new high-rate treatment facility. The Toronto metropolitan area’s Wet Weather Flow Master Plan aims to virtually eliminate combined sewage overflows (CSO) from the sewage collection system.
