The City of Waterloo's sanitary sewer system is the network of pipes and pumping stations that carry wastewater away from our homes and businesses. As our community grows and changes, we need to make sure that this important (but almost invisible) network will meet the needs of our community.

We're working on an Addendum to the existing 2015 Waterloo Sanitary Master Plan. The purpose of this Addendum is to examine our sanitary infrastructure needs considering new planning policies, growth projections, and the current needs and issues that exist in our community. The Integrated Sanitary Master Plan will review improvements to existing sanitary infrastructure, the installation of new sanitary infrastructure, and consideration of private services to municipal servicing, through to the year 2051.

This Environmental Assessment (EA) Study is being undertaken as an Addendum to a Master Plan in accordance with the planning and design process as outlined in the Ontario Municipal Class EA document (2000, as amended) which is an approved process under the Ontario Environmental Assessment Act. This Master Plan is intended to satisfy the documentation and consultation requirements for Phase 1 and 2 of the Municipal Class EA process.
