Monitoring Wastewater Overflows and Bypasses
In older areas of the City a combined sewer system collects both storm water and wastewater. During heavy rainfalls or snowmelt, combined sewers carry large volumes of storm water that can exceed their capacity.
Learn about the City's wastewater and sewer systems, that allows for the collection and treatment of wastewater before being released back into the environment.

Sewer & Drain By-law Review
The City of Hamilton is currently undertaking a review and update of the Sewer and Drain By-law. These revisions aim to modernize the content by aligning with current practices, including industry best practices, and City policies.
The Sewer and Drain By-law is used to regulate the installation, use, maintenance, and repair of Sewers and Drains in the City of Hamilton.
Highlights of the Sewer and Drain By-law Update
- New By-law Item: Required Disconnection of Downspouts
- New By-law Item: Sewer Lateral Cross Connections
- One Parcel: One Lateral (sewer laterals are the pipes that connect individual properties to the main sewer system)
- Added ‘Administration & Enforcement’ and ‘Penalty’ sections to the By-law as defined by the appropriate sections of the Municipal Act, 2001
Public Information Centres - PIC
The City is seeking feedback on the proposed updates from the public and interested stakeholders. Public Information Centres (PIC) were held to provide the public the opportunity for review the proposed changes and provide feedback and ask questions. Proposed by-law changes will be presented to Hamilton City Council in Fall 2023.
