Have you ever wondered what happens to the water you flush down the toilet or the drain?

Wastewater runs into the sewer system and through several kilometres of pipes to one of Gatineau's two wastewater treatment plants.

The wastewater treatment plant in the Gatineau sector handles wastewater from Aylmer, Hull and Gatineau. The water from Buckingham and Masson-Angers is treated in the plant in Masson-Angers.

In total, more than 62 billion litres of wastewater is treated annually, which is the equivalent of 33 Olympic stadiums the size of Montréal's! The treated water is then discharged into the river. The treated water undergoes numerous controls to ensure that it meets the Government of Quebec's standards set out in the Regulation respecting municipal wastewater treatment works.
