Haw. Code R. § 11-10-15 - Public freshwater swimming pools

(a) Water supply:

(1) The water supply serving a public freshwater swimming pool shall meet the requirement of chapter 11-20, Rules Relating to Potable Water Systems, except that the director may approve the use of water from natural sources.

(2) Where both potable and nonpotable water systems are used to serve a public freshwater swimming pool, the systems shall be piped to prevent cross-connections or back-siphonage.

(3) All portions of the potable water supply system serving the public freshwater swimming pool and auxiliary facilities shall be protected against backflow.

(4) Potable water introduced into the public freshwater swimming pool, either directly or to the recirculation system, shall be supplied through an air gap or other approved means.

(b) Water quality:

(1) The public freshwater swimming pool water shall be maintained in an alkaline condition as indicated by a pH between 7.2 and 7.8.

(2) The chlorine residual in the public freshwater swimming pool shall be at least 0.6 parts per million. The director may accept other disinfecting chemicals or apparatus registered by the United States Environmental Protection Agency when they have been adequately demonstrated to provide a satisfactory residual effect which is easily measured and equally effective under conditions of use as the chlorine concentration required under this section.

(3) The chemicals or apparatus used in controlling water quality shall not be dangerous to public health, create objectionable physiological effects, or impart toxic properties to the pool water. Any chemical that is to be used for algae control shall be approved by the department before use.

(4) The water shall have sufficient clarity at all times so that a disc which is six inches in diameter and of a color of high contrast to the color of the public freshwater swimming pool bottom can be seen from outside the pool when placed on the floor of the public freshwater swimming pool at the deepest point. The public freshwater swimming pool shall be immediately closed if the public freshwater swimming pool fails to meet this requirement.

(5) Failure to meet the requirements set by this section shall constitute grounds for immediate closing of the public freshwater swimming pool when the director determines that there is an immediate risk to human health. The operator may reopen the public freshwater swimming pool for public use when the department determines that all requirements of this section have been met and there is no immediate risk to human health.
