Water Management

Watermain Replacement & Flushing

Every year, the City of Delta undertakes an annual watermain replacement program to ensure the municipality's water distribution system operates as efficiently as possible and residents have access to clean, safe drinking water. Sites are selected based on a number of factors, including the age of the watermain, frequency of leaks, and other planned infrastructure improvements. The water service from the new water main up to property lines will be renewed and a water meter box will be installed. Residents who want to participate in our Voluntary Water Meter Program can email or call 604-946-3260.

Residents should be aware that Delta's watermain, and the municipal service to each property, are typically being replaced due to age. You may wish to have your private piping inspected by a qualified person when the municipal system is replaced. 

Backflow Prevention

Help keep our drinking water clean and healthy by preventing cross connections on the property. Backflow prevention devices help protect public safety by preventing potable water contamination in such critical areas as municipal water systems, food processing plants, medical and dental water supplies, and many industrial applications.

You must have your backflow preventer tested annually or immediately after a backflow preventer has been:

  • relocated,
  • replaced,
  • repaired or cleaned internally, or
  • changed or altered in the piping that supplies the backflow preventer.
