Backflow Prevention and Cross Connection Control Program
The program is designed to set standards for backflow prevention assembly installation, maintenance, and testing that will systematically and effectively help to prevent contamination or pollution of the ONWASA potable water supply.
A cross connection is a temporary or permanent connection between the public water supply and a source of non-potable water. One example of this is the piping between a customer's drinking water supply and an irrigation or sprinkler system. View more on the Cross Connection Control Program here.
All backflow prevention assemblies must be installed by a licensed plumber.
