2. Why is Sweetwater Authority required to inspect the size of my existing/proposed private water supply pipeline?

Sweetwater Authority water meter sizing is based on the Authority Design Standards, CA Plumbing Code, and the National Fire Protection Association, if applicable. Therefore, to confirm compliance with these Standards, the Authority inspects the sizing of the private pipeline to ensure water capacity and minimum water pressure is provided for the service.

Properly sized private water supply pipelines provide:

  • Adequate water capacity
  • Sufficient residual water pressure to avoid cross-connection
  • Adequate water pressure to operate appliances
  • Sufficient flows
