Who is required to have a backflow prevention assembly?
State and Federal law requires that water suppliers protect their potable water systems from contamination. When a determination is made, either by plan check and/or inspection, that the potable (drinking) water system may be subject to contamination through a backflow condition, the customer will be notified and required to install an approved backflow prevention assembly.

The district makes these decisions based on a case-by-case basis. Residential, commercial, and industrial customers demonstrating a high potential for contaminants to enter the potable water system must install, test, and maintain backflow prevention assemblies.
