Funding Source: No funding required for this action. Recommended Action: Motion to: Adopt Resolution No. o706-?-/a Adopting the Amended Cross-Connection Control Program. Alternative Action(s): Do not adopt the resolution and instruct staff on how to proceed. Analysis: Section 14.16.190 of the Municipal Code requires that the City maintain a Cross-Connection Control Program throughout the Huntington Beach Water System service area. The purpose of the program is to protect the public water supply against actual or potential cross-connection. One method of preventing potential cross-connection is through the use of a backflow device. Many private homeowners, businesses and City facilities are equipped with these devices. 02-021 Feb 19 Dills (Cross Connection Resoluton).doc 02/11/02 8:14 AM I I REQUEST FOR ACTION MEETING DATE: 2/19/02 DEPARTMENT ID NUMBER: PW 02-021 Each backflow device in the City must be tested and passed on an annual basis. The Public Works Water Division monitors and enforces a program whereby each device owner must comply with the annual testing requirements. The Orange County Health Care Agency now requires that any individual testing these backflow devices hold a valid tester's certification issued by that agency. The resolution presented amends Resolution No. 5921 specified in the Municipal Code and requires this tester's certification and the approval of the Water Division Water Quality Section to test within Huntington Beach.

Whenever the City Water Division determines that backflow protection within the user 's premises is adequate to protect the public water supply from backflow contamination, the water supplier, at its discretion, may waive, the requirement to provide backflow protection at the - user ' s connection . 5 . The City Water Division may require the water user to provide backflow protection at the users connection or within the users premises, or both. C . Type of Protection Required. 1 . The type of protection that shall be provided to prevent backflow into the approved water supply shall be commensurate with the degree of hazard that exists on the consumer ' s premises . The type of protective device that may be required (listing in an increasing level of protection : includes : Double Check Valve Assembly (DC) , Reduced Pressure Principle Backflow Prevention Device (RP ) , and an Air-gap separation )AG) . The water user may choose a higher level of protection than required by . the city. The minimum types of Backflow protection required to protect the approved water supply, at the user 's water connection to premises with varying degrees of hazard are given in Table 1 . Situations which are not covered in Table 1 shall be evaluated on a case by case basis and the appropriate backflow protection shall be determined by the city or health agency.
