Water Conservation

Storm pond with shrubsWater conservation and reuse is core to Waterfront Toronto's vision. Our Minimum Green Building Requirements include two water-related provisions: 1) Water efficient landscaping: 100% of the water used for landscaping must come from non-potable sources; and 2) Water use reduction: 40% reduction in potable water use for indoor flow and flush fixtures.

Waterfront Toronto has also implemented water conservation and reuse efforts in its major parks. 

Sherbourne Common

Sherbourne Common is the first park in Canada to integrate a stormwater management system in its design. A combination of collected stormwater and water drawn from Lake Ontario is treated in a UV facility located below the pavilion on the south side of the park. After its treatment, the water is lifted nearly nine metres to the top of three dramatic art sculptures on the north side of the park, then discharged into a wetland feature and through a 240 metre long water channel that travels the full length of the park, and finally released into Lake Ontario. The treated water is also used for irrigation and for the washroom facilities in the park, greatly reducing the need for potable water.

Currently, only water drawn from Lake Ontario is being used in the system. Stormwater will be integrated when the precincts are further developed.

Corktown Common

A stormwater recycling system in Corktown Common minimizes the amount of treated potable water used for park maintenance needs.

All of the park's stormwater, as well as the water discharged from the splash pad feature, is treated using ultraviolet sterilization equipment before being moved to underground storage cells located in the central lawn. The treated water is used for irrigation, park maintenance and to flush the marsh.

Green Infrastructure

Waterfront Toronto strives to integrate green infrastructure into every element of urban development. Green infrastructure is defined as natural systems and human-made vegetative technologies that provide ecological and hydrological functions and enhance healthy and sustainable living. This can take many forms such as protecting, restoring and creating natural areas, developing green roofs, establishing community gardens, rain gardens, and bioswales, as well as implementing technologies like permeable paving, cisterns, and soil cells. Waterfront Toronto has implemented many of these strategies and technologies to minimize stormwater runoff and enhance water quality.
