In Quebec, a significant portion of the water and sewer infrastructure was constructed during a boom period from the 1950s to the 1990s. As a result, many systems are now reaching critical stages of deterioration, impacting not only water delivery and wastewater treatment but also the broader housing market. The aging infrastructure is becoming a bottleneck, stalling potential housing developments as municipalities struggle to upgrade or replace outdated systems. Treatment plants, which are essential for purifying drinking water, are often operating under duress, unable to meet growing demands imposed by both population increases and modernization initiatives. Additionally, sewer pipes, which were designed for a specific lifespan, are often reaching or exceeding their half-life, leading to concerns about the reliability and safety of these systems. This situation presents challenges for urban planners and local governments as they attempt to facilitate new housing projects amidst infrastructure limitations, ultimately affecting housing availability and affordability in Quebec.
