Purity of Water | La Pureté de l'eau

Water’s journey
A - From the Saint-Lawrence River, a pumping station
(image, right) draws water into the aqueduct.
B - After a journey of about 1.5 kilometers, the water
goes through a first filtration at the Usine Charles J. Des
Baillets Treatment Plant.
C - The water continues along the Canal l’Aqueduc for
nearly 7 kilometers until it reaches the Usine Atwater
Treatment Plant.
D - Now underground, most of this twice-treated water
travels uphill to the Usine McTavish Reservoir and
pumping station, 3.5 kilometers due North, where it is
tested.
E - The reservoir distributes potable water all over the
city of Montreal, including to a single residence in the
Southwest burrough.
