TORONTO IS embarking on the largest and most significant
stormwater management program in the city’s history. This program
will greatly improve the water quality in the Lower Don River, TaylorMassey Creek and along Toronto’s Inner Harbour by keeping combined
sewer overflows out of our waterways by upgrading technology and
increasing the system’s capacity to capture, transport and treat them.
The project consist of an integrated system of tunnels, storage shafts,
connections, an integrated pumping station, a high-rate treatment
facility, a real-time control system and wastewater treatment plant
upgrades. The program is made up of several individual projects that
will work together, including the Don River and Central Waterfront Wet
Weather Flow System, the Ashbridges Bay Treatment Plant (ABTP)
Integrated Pumping Station, ABTP Ultra-Violet (UV) Disinfection
Facility, ABTP Landform and high-rate treatment facility, and the ABTP
Outfall. •
