Member Agencies

The San Diego County Water Authority’s mission is to provide a safe and reliable supply of water to its member agencies serving the San Diego region. When formed on June 9, 1944, the Water Authority initially served nine member agencies. The Water Authority now has 24 member agencies in San Diego County.

 

The Water Authority's member agencies are comprised of:

  • 6 cities
  • 5 water districts
  • 3 irrigation districts
  • 8 municipal water districts
  • 1 public utility district
  • 1 federal agency (military base)

The member agencies are represented through a 35-member Water Authority Board of Directors. A member of the San Diego County Board of Supervisors also serves as a representative to the Water Authority Board.
