About The Project
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, Taylor-Massey Creek and along Toronto’s Inner Harbour by keeping combined sewer overflows out of waterways by upgrading technology and increasing the system’s capacity to capture, transport and treat them. The project is comprised 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.
