For the purpose of this chapter, certain words and terms shall be used, interpreted and defined as set forth in this section.
“Backflow” means the flow other than the intended direction of flow of any foreign liquids, gases or substances into the distribution system of the public drinking water system of Kalama.
“Backflow prevention device” means a device manufactured and intended to counteract backpressure or prevent backsiphonage into the public drinking water supply system as approved by the Washington State Department of Health for that purpose.
“Contamination” means the entry into, or the presence in, the public drinking water system of any substance or matter when present in drinking water above an acceptable level that may adversely affect the health of the consumer and/or the aesthetic qualities of the water consumed.
“Cross-connection” means any physical arrangement whereby public drinking water supply is connected, directly or indirectly, with any other water supply system, sewer, private well, drain, conduit, pool, storage, reservoir, plumbing fixture, or other device or vessel which contains or may contain contaminated water, sewage or other waste or liquids of unknown or unsafe quality which may be capable of imparting contamination to the public water supply system of Kalama as a result of backflow. (Ord. 941 §§ 1 (part), 2, 1996; Ord. 738 § 1, 1987).

No water service connection to any premises shall be installed or continued in use and no water service shall be provided by Kalama unless Kalama’s water supply is protected by backflow prevention devices as may be required by this chapter or the Washington Administrative Code Chapter 248-54 or any superseding code section. The installation or maintenance of a cross-connection which will endanger the water quality of the potable water supply of the city shall be unlawful and is prohibited. Any such cross-connection now existing or hereafter installed is declared to be a public nuisance and the same shall be abated. (Ord. 738 § 2, 1987).

The control or elimination of cross-connections shall be in accordance with Washington Administration Code Chapter 248-54 or any superseding code section and the policies, procedures and criteria for determining appropriate levels of water system protection shall be in accordance with the latest edition of appropriate manuals of standard practice pertaining to cross-connection control approved by the Secretary of the Washington Department of Health or his authorized agent. The Kalama public works director shall have the authority to establish requirements more stringent than state regulations if he deems that existing conditions so dictate. (Ord. 941 § 1 (part), 1996; Ord. 738 § 3, 1987).

Backflow prevention devices shall be installed where, in the judgment of the Kalama public works director, the nature and extent of the activities, or the materials stored on the premises receiving or to receive public water supply service, would present an immediate and dangerous hazard to health and/or be deleterious to the quality of the Kalama public drinking water system should a cross-connection occur. (Ord. 738 § 4, 1987).

Backflow prevention devices required by this chapter shall be installed at the meter, or at the property line of the premises when meters are not used, or at a location designated by the Kalama public water director. The device shall be located so as to be readily accessible for maintenance and testing and, furthermore, where no part of the device will be submerged. All such devices to be installed shall be a model approved by the Kalama public works director and shall be installed under his supervision and with his approval. Backflow prevention devices installed pursuant to this chapter shall be inspected and tested annually, or more often if necessary, by a licensed tester at the customer’s expense. (Ord. 738 § 5, 1987).

Water service to any premises receiving its water from the Kalama public drinking water system shall be contingent upon compliance with all rules and regulations of the Washington State Department of Health and the city. Service shall be discontinued to any premises for failure to comply with the rules and regulations of the department or the city. (Ord. 941 § 1 (part), 1996; Ord. 738 § 6, 1987).
