I want to connect my underground irrigation system to the City potable water in addition to the CID or the KID, what is the proper way to connect to both systems?

To connect to both Columbia Irrigation District (CID), Kennewick Irrigation District (KID), and the City's potable water system you will need to install a Reduced Pressure Backflow Assembly (RPBA). You will need to have your RPBA inspected by the City Cross Connection Specialist and tested by a certified backflow tester once you have installed your assembly. You are also required to have your RPBA tested annually by a certified backflow tester.

Another option: If your irrigation service is interrupted use your garden hoses connected to your home's exterior faucets. This option does not require you to install an RPBA and have the RPBA annually tested.

Please note you can not connect garden hoses from your home's exterior faucets to your underground sprinkler system.
