What to check for Riverside

Riverside's developer and security materials make fire-protection assemblies a real local angle, not an afterthought.

  • Due basis: Riverside Public Utilities says each installed backflow device must be tested for proper operation at least annually, and it makes the customer responsible for following up with the contracted tester and assuring reports are submitted by the due date.
  • Who is affected: Commercial, industrial, irrigation, fire protection, and other Riverside service connections that the utility's cross-connection control program requires to have a backflow assembly.
  • Program phone: 951-351-6167
