Article VII — Backflow and Cross-Connection Control

§ 35-52. Responsibility for backflow prevention. [Ord. No. 1228-14; Ord. No. 1236-15.]

Oakdale Municipal Code · 2026-07 edition · updated 2026-09-27 · Oakdale

Under section 7583 through 7605 of Title 17 of the Code of California Regulation relating to crossconnection, the City has the primary responsibility to prevent water from unapproved sources or any other substances from entering the public water system. The City will insure that adequate backflow and backsiphonage protection is maintained on each customer's water service directly connected to the City water system. Each customer will have primary responsibility for preventing contamination and pollutants from his or her on-premises water service facilities from entering the City's water system as required by the Program and the Health Agency.

The City will not be responsible for any loss or damage directly or indirectly resulting from or caused by any improper or negligent installation, operation, use, repair, maintenance, replacement of or interference with any approved backflow prevention assembly required to be installed and operated by any customer or other person in accordance with the Program.

Each customer should be aware that the installation of a backflow prevention assembly may result in a closed-plumbing system within the customer's premises.

As such, a customer may need to make appropriate provisions for thermal expansion within their system, i.e. the installation of thermal expansion devices and/or pressure relief valves.

A customer shall bear all costs for installing an approved air gap separation or approved backflow protection assembly required by the Program. All air gap separations and approved backflow prevention assemblies shall be kept in good working order and in safe condition. A customer shall repair or replace any existing device or assembly determined by the City in its sole discretion to be unapproved, defective or not providing the level of protection required by the City and applicable law. The customer shall be responsible for obtaining any plumbing permits necessary to comply with this article.
