Backflow / Cross Connection

The Backflow and Cross Connection Division is responsible for monitoring, inspecting, and ensuring business and home owners who need to have appropriate backflow devices installed to eliminate the potential to pollute the potable water supply are informed and installed to protect the water system customers.

Backflow Prevention and Cross Connection Control Program
The program is designed to:
  • Protect the public by establishing minimum standards
  • Educate and enforce the minimum standards
  • Promote the elimination or control of existing cross connections (actual or potential) which could create backflow

The program also sets standards for backflow prevention assembly installation, maintenance, and testing that will systematically and effectively prevent contamination or pollution of the ONWASA potable water supply.
