The City of Thunder Bay’s Bare Point Water Treatment Plant receives the water we use every day and takes it through many different processes before it returns through the extensive distribution system to our homes and businesses.

How it works

The Plant can provide up to 113.5 million litres of water per day, through eight pressure zones, seven pump-stations, four reservoirs and one standpipe. It uses  membrane ultra-filtration technology to treat the water with sodium hypochlorite for disinfection and sodium hydroxide to increase the pH for reducing lead levels at the tap.

Gravity-fed water

At Bare Point, gravity feeds raw water into the plant through a 1350 mm diameter pipe 1 km from the shoreline. Screens remove debris and particles from the raw water where it enters the plant.


The Treatment Plant was originally built in 1903 and expanded in 1978. In 2007, the plant underwent a major upgrade and now provides all the water for the City.
