Notice of study commencement: City of Guelph Municipal Class Environmental Assessment for the Water Supply Master Plan Update

We’re updating our Water Supply Master Plan!

The City of Guelph is updating the 2014 Water Supply Master Plan (WSMP) to review our municipal water supply sources and identify priorities, including sustainable water supply options from now until 2041.

Today, our existing water supply fulfills the City’s commitment to providing a safe and reliable supply of water. Our WSMP update will look to the community to discuss how best to manage this vital supply so that we continue to provide the same high level of service to Guelph residents.

The updated WSMP will provide short-term, mid-term and long-term water supply options to ensure we can continue to meet the demands of Guelph’s growing population. When investigating existing and new water supply options – like new groundwater sources in and outside of the City and local surface water sources – we’ll consider things like water quality and quantity, climatic conditions, economic factors and any relevant regulations.

When we’re done – after our WSMP update is reviewed by the Guelph community and approved by Council – we’ll have identified constraints and opportunities related to our existing water supply system. We’ll also have evaluated and prioritized individual projects to increase the capacity of our existing system.

The WSMP update will be readily updated at approximately five-year intervals.
