As a result of climate change, the demand for drinking water in Quebec is likely to change over the coming decades, due in particular to rising temperatures and longer rain-free periods. In this context, it is necessary for Quebec municipalities and MRC to anticipate these changes in order to ensure sustainable water management and to maintain and develop drinking water and wastewater infrastructures that are adapted to needs.

The main objective of the project is to develop recommendations so that Quebec ministries, municipalities and MRC can take into account the impacts of climate change in their projections of future residential drinking water consumption on their territory. This project will recommend to Quebec ministries, municipalities and MRC percentages of variation in future residential drinking water consumption linked to climate change for a range of urban typologies in southern Quebec. Ultimately, the simple tools developed in the Quebec context will help raise awareness among decision-makers and technical staff of the impact of climate change on residential water consumption.
