Cross-Connection Control Program
The Environmental Management Department (EMD) Cross-Connection Control Program is responsible for oversight of the tracking and notification of Point of Service (external) backflow protection devices in Sacramento County, pursuant to Chapter 6.30 of the Sacramento County Code and sections of the California Health and Safety Code. The purpose of a backflow device is to protect the public health by preventing the flow of any unwanted material back into the Public Drinking Water systems.
This includes devices such as backflow prevention assemblies for fire systems, irrigation applications and commercial buildings. Any external backflow device that is required to be installed is required to be tested annually. A list of certified backflow testers is provided below for your reference.
The Cross-Connection Control Program web portal allows testers to maintain their annual registration and submit backflow assembly test results, electronically. More information on the portal is available from EMD quick links.
