According to the latest data updated on July 9 by the Ministère des Affaires municipales et de l'Habitation (MAMH), only Terrasse-Vaudreuil, Vaudreuil-Dorion and Saint-Clet met the drinking water consumption target set by the MAMH for 2022.

Respectively, the three municipalities recorded residential consumption averages of 160, 199 and 158 liters, per person, per day (L/pers/d), while their target was less than 200 L/pers/d. 

According to the data, Ville de Rigaud ranks first among Vaudreuil-Soulanges towns with the highest residential consumption of drinking water, with 353 L/pers/d in 2022. What's more, while the majority of municipalities recorded a decrease in consumption compared to 2021, Rigaud saw an increase from 275 L/pers/d in 2021, to 353 L/pers/d. 

By e-mail, however, the City of Rigaud was keen to point out that the data in the 2022 report includes both industries, businesses and institutions (ICI) in addition to residential, since the City did not read the meters installed on ICI this year.

Pointe-des-Cascades and Notre-Dame-de-l'Île-Perrot also recorded increases in residential drinking water consumption in 2022, compared with 2021, rising from 220 L/pers/d to 253 for the former and from 222 L/pers/d to 279 for the latter.

It should be remembered that the volume of water consumed per person per day in the residential sector is greater in Quebec than in Ontario (184 L/pers./d) and Canada as a whole (220 L/pers./d). According to the latest data, in 2022, Quebec residential consumption will reach 253 L/person/day.
