Village of East Aurora, NY § 263-15 § 263-15 WATER FOREMAN — The Water Foreman of the Public Works Department of the Village of East Aurora, or his/her authorized representative. WATER SUPERVISOR — The consumer, and/or owner of premises, and/or a person the premises charged with the responsibility of complete knowledge and understanding of the water supply piping within the premises and for maintaining the consumer's water system free from cross connections and other sanitary defects, as required by this chapter and all other required regulations and laws. C. "Shall" is mandatory; "may" is permissive. D. Protection required. (1) Where protection is required. The water system shall be required to maintain a degree of protection commensurate with the degree of hazard regardless of whether the hazard is immediate or potential. To that extent, the Cross Connection Manual published by NYSDOH shall be used as a guide to determine where protection is required. It shall be the responsibility of the water user to provide and maintain such required protection devices and such devices shall be of a type acceptable to the NYSDOH. (2) Type of protection. The type of protective device required shall depend on the degree of hazard as tabulated below: (a) At the service connection to any premises where there is an auxiliary water supply handled in a separate piping system with no known cross connection, the public water supply shall be protected by an approved reduced pressure zone device. (b) At the service connection to any premises on which a substance that would be objectionable, but not necessarily hazardous to health if introduced into the public water supply, is handled so as to constitute a cross connection, the public water supply shall be protected by an approved double check valve assembly. (c) At the service connection to any premises on which a substance of unusual toxic concentration or danger to health is or may be handled, but not under pressure, the public water supply shall be protected by an air gap separation or an approved reduced pressure zone backflow prevention device. If an air gap is installed, it shall be located as close as practical to the water meter, and all piping between the water meter and receiving tanks shall be entirely visible. A reduced pressure zone device when installed shall be located as close as possible to the property line. (d) At the service connection to any premises on which any material dangerous to health, or toxic substance and toxic concentration, is or may be handled under pressure, the public water supply shall be protected by an air gap separation. The air gap shall be located as close as practical to the water meter, and any piping between the water meter and receiving tanks shall be entirely visible. If these conditions cannot reasonably be met, the public water supply shall be protected with an approved reduced pressure zone backflow prevention device and it shall be located as close as possible to the property line.
