Public Works & Engineering

The Public Works and Engineering Department operates and maintains the engineering infrastructure essential for a high quality of life in Duncan.

This department delivers key services to the public, including Garbage, Recycling and Yard Waste Collection, Water and Sewer infrastructure management, Parks maintenance, mapping, road works and capital projects.

Road Maintenance

Street cleaning removes dirt and debris from City streets to provide an aesthetically pleasing and healthy environment for City residents. The City’s Sweeper is equipped with a vacuum, which picks up the swept debris and puts it in a hopper at the Public Works yard.

Street cleaning reduces the dirt and debris going into storm sewers, thus enhancing the quality of storm water going into the Cowichan River. Street sweeping occurs every third week during the year, provided ice and snow are not present on the streets.

The City of Duncan does not clean strata access roads. Please contact your strata council or management company for information on sweeping in your complex.

Below are some useful tips to allow for a clean sweep of debris from city streets:

  • Remove vehicles (where practical), basketball hoops or other items from the street that may impede the street sweeper from cleaning debris from gutters.
  • Keep tree branches, bushes and other foliage trimmed back to prevent them from being tangled in the sweeper’s brushes.

Whenever we have snow, the City’s plows will clear the busiest streets first, then downtown streets, and then residential streets. If snow continues to fall, crews will work throughout the day and night to keep the roads with the highest priority clear before clearing residential streets.

Please remember that owners are required to ensure that snow or ice is removed from sidewalks in front of residences and businesses.

Current Capital Projects

The City of Duncan will be undertaking a number of capital projects in 2021.  Prior to starting these projects, affected residents and business owners will be provided scheduling information.

Traffic control personnel and signage will be present to safely guide pedestrians and drivers around the construction. We thank everyone for their cooperation and understanding.
