Water Supply Master Plan

Water Supply Master Plan update (2019)

The City of Guelph has updated the 2014 Water Supply Master Plan to review our water supply sources and identify priorities, including sustainable municipal water supply options, from now until 2051.

Background and process

Today, our existing water supply fulfills the City’s commitment to provide a safe and reliable supply of water. The Master Plan – updated approximately every 5 years – provides short-term, mid-term and long-term water supply options to ensure we can continue to meet the demands of Guelph’s growing population.

The current Master Plan update was initiated in 2019 and followed Phases 1 and 2 of the Municipal Class Environmental Assessment (MCEA) in accordance with Approach #1 of the Master Plan Process described in the MEAC Manual (amended in 2015) by the Municipal Engineers Association. Through analysis and evaluation of alternative projects, and input from the public, Indigenous Peoples, the Community Liaison Group, and agency and municipality consultation, the recommended preferred water supply alternatives were selected and refined. The Master Plan also identifies next steps for how the City may proceed with future water supply projects. This current update was coordinated with the Official Plan and contains plans for execution of individual projects consisting of Class Environmental Assessment Schedule B and C activities.

The full draft Master Plan update was placed on the public record for a 90-day review period in accordance with the requirements of the MCEA process. This period began on January 10, 2022 and ended on April 10, 2022. Comments were solicited from the general public, as well as the County, Townships, regulatory agencies and Indigenous communities. Meetings were held with representatives from Wellington County, Guelph-Eramosa Township and Puslinch Township to present the report and to receive comments. A meeting was also held with the Ministry of Environment, Conservation and Parks. Comments were used to update and revise the report.

The Water Supply Master Plan Update was approved by City Council on June 27, 2022. The final Water Supply Master Plan Update Report is provided at the links below.
