Wastewater Abatement Program

The Wastewater Abatement program allows eligible commercial and industrial ratepayers to apply for an assessment of the flow differential between water use and sewage discharged to the city's sanitary sewer and combined sewer systems. Eligible commercial and industrial consumers include those that divert a minimum of 25% of their purchased potable water from the sewer works. Water diverted from the sewer works for uses such as ground irrigation, recreation and off-premise are not eligible for abatement.

You are not eligible for this program if your premise is non-compliant with any of the provisions of the Sewer Use By-law No. 14-090 or if you are not in good financial standing with the City.

Upon approval, your wastewater/storm charges on your water bill could be reduced to better reflect your use of the City's sewer system.

To apply for the Wastewater Abatement program, you need to submit:

  1. A completed Wastewater Abatement Program Application form (Excel, 58 KB).
  2. A cheque or money order for applicable fees made payable to the City of Hamilton.
