Businesses in Toronto may be eligible for a rebate on water not discharged into the sanitary sewer system (i.e. water evaporated from cooling towers or used to make a product). The rebate is based on the percentage of water not returned to the sanitary sewer system, and is applied to the sewer portion of the water rate.

Water used outdoors (i.e. for irrigation) is not eligible for the Sewer Surcharge Rebate Program. For full eligibility criteria, read By-law No. 849 – Water and Sewage Services and Utility Bill.
