Water Supply System

The Regional Municipality of Durham is responsible for the treatment, storage and distribution of drinking water to every consumer on the system. Customers are from the following areas: Pickering, Ajax, Whitby, Brooklin, Oshawa, Courtice, Bowmanville, Newcastle, Newtonville, Orono, Uxbridge, Uxville, Port Perry, Blackstock, Greenbank, Sunderland, Cannington and Beaverton.

Water for the Region’s municipal water supply systems comes from three sources: Lake Ontario for our southern municipalities; Lake Simcoe for Beaverton; and ground water wells for the remaining communities.

Water is treated and tested in accordance with the Ministry of Environment requirements, which regulate both quality and quantity. After treatment, water is delivered to the customer through a system of watermains, pumping stations and reservoirs.

The Regional Municipality of Durham operates and maintains:

The booster pumping stations and storage facilities are located throughout the distribution systems to pump and store water at sufficient pressure. These booster pumping stations and reservoirs are operated so that peak water consumption demands can be met while an adequate supply of water is available to meet extraordinary demands, such as fire emergencies.
