ES-1. Introduction
ES-1.1 Background
The Regional Municipality of Waterloo (Region) completed a Wastewater Treatment
Master Plan (WWTMP) in 2007 that provided strategic long-term planning for the
Region’s wastewater treatment services and recommended preferred alternatives to
meet growth needs to the year 2041. In light of recent trends in wastewater flows
and population growth, regulatory requirements, and climate patterns, the Region has
initiated this study to update the WWTMP. The goal of this study (the 2018 WWTMP
Update) was to develop a current, comprehensive, cost-effective and feasible
strategy to address the anticipated wastewater treatment needs of the Region over
the next 35 years that is consistent with the Region’s 2015-2018 Strategic Plan.
The 2018 WWTMP Update was completed under the Environmental Assessment Act
in accordance with Municipal Class Environmental Assessment (EA) requirements,
and provides an overall plan for the upgrade and/or expansion of the Region’s
wastewater facilities until the year 2051. Recommendations have been developed to
accommodate future population growth, meet level of treatment needs, enhance
operations and reduce energy use. In addition to facility-specific recommendations,
recommendations benefitting all Regional wastewater facilities were also identified.
An implementation plan was also developed to identify the recommended timing and
financial impacts for the master plan growth and treatment recommendations.
ES-1.2 Service and Study Areas
The Region owns thirteen (13) Wastewater Treatment Plants (WWTPs) that have
been reviewed as part of this WWTMP Update over the 35-year planning period,
including Kitchener, Waterloo, Galt, Preston, Hespeler, Elmira, New Hamburg, Ayr,
St. Jacobs, Wellesley, Alt-Heidelberg, Foxboro Green and Foxboro Green WWTPs.
These wastewater facilities are operated and maintained by the Ontario Clean Water
Agency (OCWA), under contract to the Region.
The Region also owns seven (7) Sewage Pumping Stations (SPSs) including Spring
Valley, Bridgeport, Baden, Morningside, Rose Street, Ayr and Nith River Way SPSs.
Figure ES-1 shows the location and the service areas of key wastewater
infrastructure in the Region.
