If you are a developing multiple single-family residential units, you must obtain a permit for each single-family unit. An onsite survey may be required before a residential permit will be issued.

Permits are required for all new and replacement backflow assemblies. All commercial properties require premise isolation. District staff will evaluate the application and contact you with a total cost for your backflow permit, and arrange to take payment for the permit. Permit cost is $65.00 each for the first two assemblies and $32.50 for each additional assembly. After the permit is issued it will be sent to you by email or you can pick up a copy at our main office.
