The Region of Waterloo has approved funding for a fast-track solution to address water capacity constraint in the Mannheim Service Area.
The Mannheim temporary side stream treatment pilot allows more water to be treated faster through containers that create a side stream at the existing facility, a Region of Waterloo release said.
“The goal is to add about 25 litres per second (L/s) of water to start, followed by up to 50 L/s in the fall. When all containers are online, they could add up to 300 L/s by next year. Staff are working with partners on technical requirements,” the release said.
“The water capacity constraint is one of the biggest challenges facing our region, and we are addressing this issue immediately. This pilot program shows that council is moving as fast as we can on solutions that increase capacity, protect our communities, and support growth, while we work on longer-term repairs and infrastructure projects in partnership with our municipal and provincial partners,” Region of Waterloo regional chair Karen Redman said.
The container pilot is a bridge measure, the release noted until the Mannheim Water Treatment Plant upgrade project is complete. Both are on the list of preliminary solutions that were endorsed by council in January sand other initiatives include repairs, upgrades, and new infrastructure.
The full list of preliminary solutions is available on the Region of Waterloo website.
