Backwater Valve Subsidy Program

Drainage Services has a Backwater Valve Subsidy Program to assist homeowners to install a backwater valve. Reimbursement only applies to qualified residential property owners. The valve is normally installed on either the main sewer line where the sanitary sewer exits the house or on various branch line locations to prevent sanitary sewer backup.

There are two types of Subsidy Program:

The Regular Backwater Valve Subsidy Program

This program has been in place since 1991 and applies when a residential homeowner has experienced basement sanitary sewer backup during a storm related event. The homeowner simply calls 311 to report the basement flooding.

To qualify the following criteria must be met:

  • The residence is a single family dwelling or a separately serviced duplex dwelling
  • The dwelling was built prior to 1989
  • The sanitary sewer backup occurred in a sanitary main line as a result of a major storm event
  • The property is serviced directly from the City’s sewer system
  • A subsidy has not previously been provided for the same location

The Proactive Backwater Valve Subsidy Program

This program is for homeowners who have not experienced sanitary sewer backup and applies when funding is available from the Regular Backwater Valve Program. The homeowner must submit a request with the property location, flooding history if there is any, name, and contact number to Drainage Services in the following manner:

  • Email: BackWaterValve@edmonton.ca
  • Fax: 780-496-3601
  • Regular mail:
    The City of Edmonton
    Drainage Services
    5th Floor, Century Place
    9803 – 102A Avenue NW

  • The dwelling was built prior to 1989
  • The property is serviced directly from the City’s sewer system
