Water, nonpotable shall mean water which is not safe for human consumption or which is of questionable potability.

Water-service connections shall mean the terminal end of a service connection from the public potable water system, i.e., where the water purveyor loses jurisdiction and sanitary control over the water at its point of delivery to the customer's system. If a meter is installed at the end of the service connection, then the service connection shall mean the downstream end of the meter. There should be no unprotected takeoffs from the service line ahead of any meter or backflow prevention device located at the point of delivery to the customer's system. "Service connection" shall also include a water service connection from a fire hydrant and all other temporary or emergency water service connections from the public potable water system.

Water, used shall mean any water supplied by a water purveyor from a public potable water system to a customer's system after it has passed through the point of delivery and is no longer under sanitary control of the water purveyor.

Water system as used herein shall mean that system made up of two (2) parts: The utility system and the customer system as those are defined herein.

(Ord. No. 1848, § 4, 6-25-90)

(a) No water service connection to any premises shall be installed or maintained by the city unless the water supply is protected as required by state laws and regulations and these sections. Service of water to any premises shall be discontinued by the water purveyor if a backflow prevention device required by this section is not installed, tested and maintained, or if it is found that a backflow prevention device has been removed, bypassed or if an unprotected cross-connection exists on the premises. Service will not be restored until such conditions or defects are corrected.

(b) The customer's system shall be open for inspection at all reasonable times to authorized representatives of the director of public works to determine whether cross-connections or other structural or sanitary hazards, including violations of these sections, exist. When such a condition becomes known, the director of public works shall deny or immediately discontinue service to the premises by providing for a physical break in the service line until the customer has corrected the condition(s) in conformance with all state and city requirements.

(c) An approved backflow prevention device shall also be installed on each service line to a customer's system in all cases, before the first branch line leading off the service line wherever the following conditions exist:

(1) In the case of premises having an auxiliary water supply which is not or may not be of safe bacteriological or chemical quality and which is not acceptable as an additional source by the director of public works, the public water system shall be protected against backflow from the premises by installing a backflow prevention device in the service line appropriate to the degree of hazard.

(2) In the case of premises on which any industrial fluid or any other objectionable substance is handled in such a fashion as to create an actual or potential hazard to the public water system the public system shall be protected against backflow from the premises by installing a backflow prevention device in the service line appropriate to the degree of hazard. This shall include the handling of processed waters and waters originating from the utility systems which have been subject to deterioration in quality.

(3) In the case of premises having (1) internal cross-connections that cannot be permanently corrected and controlled, or (2) intricate plumbing and piping arrangements or where entry to all portions of the premises is not readily accessible for inspection purposes making it impracticable or impossible to ascertain whether or not dangerous cross-connections exist, the public water system shall be protected against backflow from the premises by installing a backflow prevention device in the service line.

(d) In the case of any premises where there is water or substance that would be objectionable but not hazardous to health, if introduced into the public water system, the public water system shall be protected by an approved double-check valve assembly.

(e) In the case of any premises where there is any material dangerous to health which is handled in such a fashion as to create an actual or potential hazard to the public water system, the public water system shall be protected by an approved backflow prevention device approved by the City of West Covina and the state department of health services. Examples of premises where these conditions will exist include but are not limited to chemical manufacturing plants, hospitals, mortuaries and plating plants.

(f) In the case of any premises where there are "uncontrolled" cross-connections, either actual or potential, the public water system shall be protected by an approved air-gap separation or an approved reduced pressure principle backflow prevention device at the service connection.

(g) In the case of any premises where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete in-plant cross-connection survey, the public water system shall be protected against backpressure or back-siphonage from the premises by the installation of a backflow prevention device in the service line. In this case, maximum protection will be required: That is, an approved air-gap separation or an approved reduced pressure principle backflow prevention device shall be installed in each service to the premises.

(h) In the case of premises with cross-connections to sewage lines, pumps, flushers, etc., the public water system shall be protected by an approved backflow prevention device approved by the City of West Covina and the state department of health services. Examples include sewage treatment plants and pumping stations.

(i) In the case of tanker and spray tanks, an air-gap separation or an approved reduced pressure principle backflow prevention device is required.
