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 is comprised of an integrated system of tunnels,
storage shafts, connections, an integrated pumping station, a highrate treatment facility, a real-time control system and wastewater
treatment plant upgrades. •
