SECTION 310:315-5-1. Water supply

(a)   Potable water supply. The water supply serving the bathhouse and all plumbing fixtures, including drinking fountains, lavatories, and showers, shall be treated in accordance with the requirements of the State Department of Health for drinking water.

(b)   Pool water supply. The water supply for artificially constructed bathing places shall meet the requirements as set forth in 310:315-5-1, "Pool water quality."

(c)   Backflow preventers. All portions of a public water distribution system serving the pool and ancillary facilities shall be protected against backflow. Water introduced into the pool either directly or through the recirculation system shall be introduced into the pool through an air gap providing two pipe diameters or six (6) inches vertical distance between the maximum flood level of the pool and the lowest point of the inlet pipe. The coping or deck constitutes the flood level, not a drain. In the case of other connections to a public distribution system, the supply shall be protected by an air gap whenever possible. When such connections are not possible, the supply shall be protected by a suitable backflow preventer installed on the discharge side of the last control valve to the fixture, device, or appurtenance. All hose bibs in the bathing facility area shall be so equipped. The requirements of the American National Standards Institute (ANSI) A40.6-1943; the American Society of Sanitary Engineering (ASSE) 1001-1970; ASSE 1011-1970, ASSE 1012-1972, ASSE 1013-1971, ASSE 1015-1972; or the American Water Works Association (AWWA) C506-69, or latest revisions thereof, will be used in determining substantial compliance with this requirement.

(d)   Pool water quality. Unless pool water is to be supplied from an approved and properly operated public water supply system routinely analyzed by the State Department of Health, an analysis of the proposed pool water supply shall be submitted with the plans and specifications or as part of a preliminary engineering report. The analysis shall include, as a minimum, the following parameters: pH, total alkalinity, dissolved solids, hardness both carbonate and non-carbonate, copper, iron, manganese and turbidity. Should any of the above parameters exceed the maximum limit set forth in the Public Bathing Place Regulations, design and specifications of necessary treatment units required to reduce the contaminant to an acceptable level must be made a part of the swimming pool plans.

(e)   Drinking fountains. Approved type angle-jet fountains with approved water supply under adequate and regulated pressure must be provided in locations available to pool patrons. In the case of non-municipal pools, this requirement will be considered met by compliance with 310:315-7-7, "Bathing places not open to the general public."
