Mitigate the burden on rate-payers arising from costs associated with remediating contamination of the district water supply due to backflow from private water sources caused by a water user's failure to comply with the requirements of the ordinance codified in this chapter.

(2)

Incorporation of Regulations. The regulations of the California Department of Public Health, Title 17, California Code of Regulations, sections 7583—7605, inclusive, hereinafter referred to as Title 17, the ordinance codified in this chapter, County Ordinance Code chapter 4.72 (Backflow Prevention Ordinance) and all amendments thereto, are hereby adopted, incorporated by references herein and made a part hereof, insofar as the same are applicable to the protection of the district's water distribution system.

b)

The property owner or water user is responsible for the installation, maintenance, and appropriate testing, including any associated costs, of any protective device or assembly as required and as directed by the district or its designee.
