The Region of Durham is responsible for the planning, construction, operation and maintenance of the sanitary sewer system that carries wastewater from buildings to either pumping stations or the water pollution control plant. 

Plumbing fixtures such as toilets, sinks, tubs and showers, appliances such as dishwashers and washing machines, as well as the floor drain in your basement are connected to the sanitary sewer.

The City of Pickering is responsible for stormwater management. Stormwater is collected through ditches, culverts, catch basins, storm sewers and stormwater ponds that eventually discharge to receiving water bodies such as local creeks and/or Lake Ontario.
