The first Pointe-Claire water treatment plant was inaugurated in 1918.

Forty years later, in 1958, the increasing needs of our growing population and fast expanding industrial park required the building of a second plant with a capacity of 18,000 m per day. That capacity was upgraded to 36,000 m per day in 1963 followed by 63,000 m per day in 1969.

In 1975, major renovations raised this capacity to 118,000 m per day.

In 1990, to increase water supply to our ever-expanding industrial sector, a booster station was built in the North end of Pointe-Claire, with a reserve capacity of 9,090 m per day.

Two years later, in 1992, the plant's reserve capacity was increased to 30,910 m per day and its distribution capacity raised to 236,400 m per day.

In 1996, a second intake pipe of 1,800 mm diameter is added in the lake as well as a new screening process building.

In 2003, work slated to update the production systems served to increase the plant's daily capacity to 181,700 m per day.

In 2008, renovation to enhance production quality increased the decantation capacity from 190,900 m to 227,000 m per day.
