City of Toronto industrial and commercial water customers may be eligible for a rebate on a portion of the sewer surcharge.
The sewer surcharge rebate applies to water not discharged into the sanitary sewer system (for example, water evaporated from cooling towers or used to make a product). The rebate is calculated based on the percentage of water not returned to the sanitary sewer system, and is credited on the water bill based on the sewer portion of the water rate paid.
Properties wishing to apply for the sewer surcharge rebate must meet the eligibility criteria as outlined in Bylaw No. 849 – Water and Sewage Services and Utility Bill.
