City of Toronto – Sewer Surcharge Rebate Program

Description:

Businesses in Toronto may be eligible for a rebate on water that is used on-site for their industrial or commercial processes.

Comments on Funding:

Funding is a rebate based on the percentage of water not returned to the sanitary sewer system, and is applied to the sewer portion of the water rate. The percentage by which the sewage discharge is reduced in relation to the amount of water purchased must meet the following criteria:

  1. for properties with total annual water consumption ≤1500 m3 the sanitary contribution amount is ≤ 80%;
  2. for properties with total annual water consumption>1500 m3 but ≤15,000 the sanitary contribution amount is m3 ≤ 85%;
  3. for properties with total annual water consumption>15,000 m3 but ≤ 1,500,000 the sanitary contribution amount is m3 ≤ 90%;
  4. for properties with total annual water consumption>1,500,000 the sanitary contribution amount is m3 ≤ 95%.
