(a) General circulation requirements. The circulation system consisting of pumps, piping, filters, return inlets, water conditioning equipment, disinfection equipment, surge chamber, treatment tank and other ancillary equipment shall provide adequate circulation of water and be designed to accommodate 100% of the turnover flow rate and maintain the distribution of disinfectant through all parts of the public interactive water feature or fountain (PIWF).

(b) Circulation equipment. Where circulation equipment falls within the scope of NSF and ANSI Standard 50 (NSF/ANSI-50 Standard), such equipment shall meet the standard. Conformity with NSF/ANSI-50 as evidenced by the listing or labeling of such equipment by a testing laboratory or by separate documentation is required.

(c) Turnover rate. The turnover rate for the circulation of water in a PIWF that is combined or circulated with water from a pool shall be the same as the pool. The turnover rate for circulation of water in a stand-alone PIWF shall meet the following requirements.

(1) If the PIWF was constructed prior to May 1, 2010, the turnover rate shall meet the minimum design turnover rate for that PIWF.

(2) If the PIWF is constructed or extensively remodeled on or after May 1, 2010 the minimum turnover rate shall be at least once every hour.

(1) be designed to provide ready access for cleaning and inspections, and be capable of complete draining;

(2) have an automatic water level controller; and

(3) have any makeup water introduced into the treatment tank through an air gap or by another method which will prevent back flow and back-siphonage.
