2019 Water and Sewer Information


Delivering drinking water is only the first half of the story. For customers not on septic systems, Thames Centre is also responsible for taking wastewater away, treating it, and for discharging it safely into the environment.

The Municipality owns and operates two municipal wastewater systems in the village of Dorchester, and one in  Thorndale. The first phase of the Thorndale wastewater system was completed in 2012.  Phase 2B is to begin construction in 2013.  The following streets will be serviced by this phase of the project: Upper Queen Street, Main Street, Lions Lane, Maria Street, and Agnus Street.  For more information on the Thorndale sewer project click here.
