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.

Changes to the City's drinking water system

An adjustment has been made to the pH of the City's drinking water by phasing out the addition of sodium hydroxide. Before the Summer 2020, the pH of the drinking water will return to the same level as in 2017. Lead levels are expected to increase for customers with lead service pipes. Learn more about the changes to the drinking water system. 

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 filter the water and sodium hypochlorite for disinfection. Find out more about the plant:

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.

History

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.
