Hamilton gives notice of water, wastewater and storm water master planning

Infrastructure needed for city's projected growth

April 27, 2023  By Ground Water Canada

Hamilton – Water, wastewater and storm water infrastructure is required to accommodate the city’s projected growth of 236,000 by 2051.

A strategic and comprehensive growth planning and infrastructure master planning study has been initiated to determine the short and long-term water, wastewater and storm water infrastructure needs to support growth to the year 2041, with consideration for 2041 to 2051 growth in the urban boundary expansion areas.

The integrated master plans will:


• Provide a strategic vision for the 2041 and 2051 planning horizons to accommodate future growth, and ensure safe, clean drinking water and environmental protection

• Ensure safe, sustainable and optimized water and wastewater services

• Provide a business case for the need, timing and cost of water, wastewater and storm water infrastructure in an integrated process.

The water, wastewater and stormwater master plans  are being completed following the master planning process as set out in the Municipal Class Environmental Assessment (EA) document (October 2000, as amended in 2007, 2011, 2015 and 2023), which is an approved process under the Ontario Environmental Assessment Act (EAA). This approach involves the preparation of a master plan document that satisfies Phase 1 and 2 of the Class EA process. Further investigation and consultation may apply to projects identified per the EAA requirements.

The city welcomes anyone with an interest in this study to be involved and provide input. Opportunities for input will include two rounds of public information centres (PICs) as well as direct consultation. To better engage city residents and stakeholders in ongoing projects and initiatives, the City of Hamilton has launched Engage Hamilton; an interactive online space dedicated to public engagement. All project news, updates and public participation will take place via the Engage Hamilton site:
