York Trunk Sewer and Paisley-Clythe Feedermain Class Environmental Assessment
About the project
About the Environmental Assessment
The City of Guelph has started a Class Environmental Assessment study for improvements to the York Trunk Sanitary Sewer and a new drinking water feedermain for the Paisley and Clythe Reservoirs. The Guelph Water and Wastewater Servicing Master Plan (2009) identified the need for these improvements in order to service planned growth in the City.
Renewing the City’s Water and Wastewater Infrastructure
The current York Trunk Sanitary Sewer extends from the former Guelph Reformatory Lands to the Wastewater Treatment Plant west of the Hanlon Expressway along the Eramosa and Speed Rivers. This sewer is reaching the end of its useful life and capacity due a combination of planned population and employment growth in the City and reports of poor condition in sections. A solution is required to replace and/or rehabilitate this main trunk sewer.
The Paisley-Clythe Drinking Water Feedermain is a new watermain required to increase the reliability of the supply between the City’s F.M. Woods Reservoir and Pumping Station and the Paisley and Clythe Reservoirs at the west and east ends of the City.
The York Trunk Sanitary Sewer and Paisley-Clythe Drinking Water Feedermain Class Environmental Assessment will:
- assess existing infrastructure and the environment;
- identify the problem and alternative solutions;
- determine needs for future growth;
- evaluate alternatives for routing, construction methods and mitigation measures; and
- develop a preferred alternative to meet the project objectives for both the sewer and feedermain.
This study is being planned under Schedule B of the Municipal Class Environmental Assessment process (Municipal Engineers Association, October 2000 as amended in 2007) under Ontario’s Environmental Assessment Act. The Class Environmental Assessment process includes public and review agency consultation, an evaluation of alternatives, an assessment of the potential environmental effects of the proposed improvements, and identification of reasonable measures to mitigate any adverse impacts that may result.
Construction began in March 2014 and is expected to be completed in 2015.
