Chambly's Wastewater Facility, Québec

The challenge

In Québec, million litres of water are used for industrial purposes everyday. When released into the environment without treatment, this wastewater, composed of high levels of organic and inorganic pollutants, can severely affect human health and the environment. To protect and preserve Québec's communities and natural ecosystems, all contaminated water must undergo appropriate treatment.
