Annual catch basin cleaning program set to begin

Crews set to clean 10,000 catch basins in Nanaimo


Beginning Monday, April 17, City of Nanaimo Public Works staff and contractors will be out cleaning the City's inventory of storm water catch basins.

Starting in the Duke Point area, crews will work their way north along various streets of Nanaimo. This work involves large equipment and staff working on the road. Please approach with caution and obey traffic control personnel's directions. The annual catch basin cleaning program is expected to be complete by August.

Key Points

  • During the program, storm drain grates are pulled off and the catch basin is then cleaned out using a vacuum truck. An inspection is then conducted for any deficiencies. The material is then disposed of in an environmentally safe manner.
  • Groess Environmental has been contracted to conduct the 2023 catch basin cleaning program with City of Nanaimo Public Works staff.
  • Drivers, cyclists and pedestrians are asked to watch for crews and traffic control personal on the roads, and be aware of missing grates near the work zone.


"Nanaimo's storm drains collect rainwater runoff from city streets, which then empties into the ocean. This annual maintenance program helps to divert pollutants from our waterways. In addition, it gives our staff the opportunity to inspect each catch basin to identify any needed repairs."
