Share on Facebook Share on Twitter Share on Linkedin Email this link


The Region of Waterloo’s original Sewer Use By-law (1-90) regulates discharges to Regional sewers and has remained unchanged for the last 30 years except for 2 minor amendments. Regional staff have completed an extensive review process, in consultation with local municipal staff, to develop a new Sewer Use By-law to replace By-law 1-90.

The Sewer Use By-law is a major regulatory by-law that helps protect you, workers on the sewage system, the sewage system infrastructure, drinking water supplies and the environment. This Sewer Use By-law prohibits the discharge of toxic substances and regulates contamination limits for substances discharged to sewers.

The attached draft Sewer Use By-law is the result of a multi-year comprehensive review. The Sewer Use By-laws of other Ontario municipalities along with leading Canadian municipalities were reviewed to ensure the proposed Sewer Use By-law reflects best practices and is aligned with neighbouring jurisdictions such as the Region’s of Halton, Peel, York and Niagara; and the Cities of Hamilton, Brantford and Guelph.

Public Consultation Slides located in the Document Library on this homepage provide additional detail and context on the proposed changes to the By-law and specifically how those changes may impact local businesses.

There is a survey in the tab below that you can fill out if you wish to provide feedback on the changes to the By-law. Please indicate in your comments if additional detail or a written response is required from the Region.

Consultation on the new By-law will be conducted on Engage Region of Waterloo only, as in-person contact is not possible at this time.
