Southwest Guelph Water Supply EA
Guelph’s population is growing and the City is studying whether our local water resources can meet expected demand, particularly in southwest Guelph. We’re looking into whether we can increase capacity at our existing wells and what new infrastructure would be needed to increase water supplies to accommodate expected growth.
These questions are being evaluated through a Municipal Class Environmental Assessment (MCEA) to determine longer term water supply capacity in southwest Guelph. This study is assessing the environmental impacts of using more groundwater resources and supports the design of a groundwater protection system to address drinking water quality concerns related to past operations at the Dolime Quarry.

How can I participate right now?
Join us at the last Public Information Centre in January 2027 to learn more about the preferred solutions and conclusions of the EA. Follow this page to stay updated when a date for the Public Information Centre has been announced.
