Guelph and Guelph/Eramosa Tier 3

A Tier 3 Water Budget study was completed for the City of Guelph and the Township of Guelph / Eramosa municipal drinking water systems.

The City of Guelph’s water supply system consists of 23 wells constructed within overburden aquifers and deep bedrock aquifers, and an artificial groundwater recharge system with a shallow groundwater collection system. The Township of Guelph/Eramosa has municipal systems located in Rockwood and Hamilton Drive, which are serviced by four and two bedrock water supply wells, respectively.

The main findings of the Guelph and Guelph/Eramosa Tier 3 Water Budget and Risk Assessment are:

  • The City of Guelph’s and Guelph/Eramosa Township’s wells can meet current needs.
  • The City’s Queensdale municipal well is predicted to not be able to meet future needs under normal climate conditions and during prolonged drought. 
  • Water Quantity Wellhead Protection Area (WHPA-Q) and Water Quantity Intake Protection Zone (IPZ-Q) are assigned a significant risk level.
