• Roads and maintenance
  • Info construction

The Town of Mount Royal is currently performing various operations on its sewer system to prevent a sewer main blockage and to prevent backflow of sewage into the basement of residences.

Map of upcoming work and corresponding dates

The work will take approximately four weeks to be complete. It began on March 25, 2019.

Consult a map of the upcoming work, updated regularly.

Work details

The Town uses high-powered hydro-pressure trucks that produce strong jets of water, powerful enough to dislodge any accumulation in the sewer lines.

In some cases, this cleaning of the sewers might cause some inconveniences, such as:

  • Truck noises;
  • Sewage odours for a limited time;
  • Agitated toilet water, due to air release;
  • Partial obstruction of roads.
