Waterloo, Bristol, Wellington, and Alma Trunk Sanitary Sewer Preliminary Design Study

About the project

The City’s Water and Wastewater Servicing Master Plan identifies upgrades to the City’s trunk sanitary sewer network. Wastewater from your home flows through the trunk sanitary sewer network to  the Water Resource Recovery Centre for treatment. Due to the complex layout of the trunk sewers in the project area, pictured below, we’re studying the trunk sewer network comprehensively, rather than studying individual pipes within the network on a street-by-street basis. The project area includes trunk sewers along Bristol Street, Waterloo Avenue, Wellington Street West and Alma Street. Through this project, the City of Guelph is exploring options for the trunk sanitary sewer upgrades identified in the Master Plan while also exploring how we can deliver other infrastructure improvements identified in the Water and Wastewater Servicing Master Plan, the Stormwater Management Master Plan, and through the City’s own asset management planning.

The preliminary design study will involve collecting field information (i.e. a topographic survey and soil information), evaluating design alternatives, and presenting a preliminary design for the preferred alternative that can be carried forward in subsequent detailed design and construction projects. The preliminary design documentation will be shared on this website upon completion of the project.

The Preliminary Study Area, approximately bound by Waterloo Avenue, Edinburgh Road, the Speed River, and Highway 6, including Alma Street up to Willow Road. Also, the Secondary Study Area, which includes several additional areas for which minor information will be collected for upgrades to the City’s asset database.

What’s happening this summer?

This summer and fall, the City’s contractors will collect topographic survey, legal survey and underground utility information. You may see people in the neighbourhood wearing high-visibility vests collecting this information. You may receive a notice requesting access to your backyard to collect this information.

Additionally, arborists will be in the project area to tag and map tree locations. You may see a small metal tag left behind on the tree. These tags will not harm the tree and will be removed at the end of the project.

The City will also collect information about the soil underneath the project area. You may see a large construction vehicle parked throughout the project area drilling boreholes to collect this information.
