TOP 50 WATER PROJECTS 2026
WASTEWATER
WORK AT THE Jean-R.-Marcotte treatment station
is underway to enable wastewater treatment
through ozonation—a process that injects ozone at
the end of the treatment cycle. This environmentally
advantageous solution requires several key
infrastructure upgrades, which will be completed in
phases to support full implementation by 2025.
To measure and manage runoff impacts, a study
analyzed data from the past 10 years. The findings
suggest that the volume of water potentially
discharged into the St. Lawrence would be six times
lower per hour than during the 2015 construction
period. The runoff would primarily consist of
rainwater, mixed with a small portion of wastewater.
The treatment station features an integrated
control system that prioritizes runoff sites. In the
event of flooding, water will be directed to areas of
the river with the least potential impact on human
and aquatic health. •

THE RENEWAL PROJECT will upgrade the main
treatment plant, treatment processes and treatment
technologies, as well as modernizing the facility with
necessary redundancy. It will rejuvenate the plant,
enabling it to meet the region’s forecasted potable
water demands for the years ahead.
Construction began in June on the project. Work
to date includes construction on temporary roads
and lay down areas, the start of new summer ponds,
relocation of a natural gas line, initiation of chemical
tank refurbishment, and the start of various
underground services. The plant renewal project is
expected to be completed and fully operational by
the end of 2025. •
