Sanitary Sewer

We Can Help!

The City maintains and constructs the sanitary sewer infrastructure. We ensure an effective and reliable sanitary sewage collection system and transfer to Metro Vancouver for treatment. Sewerworks is responsible for the following:

  • Flushing sanitary sewer lines
  • Clearing blockages to sanitary sewer mains and services to property line
  • Maintaining sanitary sewer manholes
  • Sanitary mains and inspection chambers

Sanitary Inspection Chamber

Each property has a service line with a sanitary inspection chamber and newer homes will also have a storm inspection chamber.  These are normally located at the frontage of the property line. Please do not landscape over them as they need to be accessible at all times.

If your inspection chamber lid is cracked or missing, please contact Public Works immediately at 604-463-9581.

Adopt a Catch Basin

We Are Looking for Your Help!

It's easy! When it's safe to do so, clear the catch basin of leaves and debris and make a path for the melting snow. You will help the streets get back to normal more quickly after weather events. 

There is no doubt that one of the most challenging times is the period right after a major snowfall when our weather turns warm again and the snow starts to melt. We've all stepped on what we thought was a packed pile of snow only to find ourselves ankle deep in ice cold water that has collected due to a clogged catch basin. Also in the fall, the catch basin near your home may be obstructed with leaves and other debris that create puddles at the side of the road.

The catch basin map shows you their locations in relation to your property line.
