(A) The following are based on the requirements of the Indiana State Department of Health's Swimming Pool Rule, 410 IAC 6-2.1, modified to fit the needs of an interactive play attraction. NOTE: Requirement E (disinfection) and F (filtration) do not apply to interactive play attractions that drain to waste.
(B) Plans. Plans must be submitted to the Indiana Department of Homeland Security, Fire Prevention and Building Safety Commission for a design release prior to construction, rehabilitation or alteration as required per Rule 675 IAC 20-5-2.
(C) Water supply. Potable water that meets the provisions of Rule 327 IAC 8-2 shall be used as the source water.
(D) Sewage disposal. All waste must be disposed of in a sanitary sewer. In some instances, IDEM has permitted the wastewater to be used for irrigation.
(E) Disinfect the recirculated water. A minimum concentration of 2.0 ppm chlorine or 4.0 ppm bromine with secondary disinfection of ultraviolet light or ozone and a pH in the range of 7.2 through 7.8 must be maintained. This higher level of disinfection is needed because the probability of fecal contamination is increased with an interactive play attraction. Also, chlorine will dissipate faster in an interactive play attraction due to the water being sprayed. Chlorine concentrations shall be monitored electronically, so the water fountain will shut off automatically if the chlorine level drops below 2.0 ppm. For interactive play attractions constructed, rehabilitated or altered after August 7, 2013, Rule 675 LAC 20-5-23 requires: secondary disinfection such as ultraviolet light or ozone in addition to chemical disinfection.
(1) Disinfection equipment shall be tested and listed for use in spray pad disinfection.
(2) Ultraviolet light dosage shall be 40 mJ/cm2 or greater.
(3) Ultraviolet light systems shall have a properly calibrated light intensity meter, automatic water flow shutoff in the event the light intensity decreases below recommended level and an alarm to advise of a malfunction.
(a) It shall be UV-C unit producing a wavelength of 254 nanometers.
(b) The standard for testing and listing of the UV unit for secondary disinfection is US EPA Ultraviolet Disinfectant Guidance Manual dated November, 2006, publication number EPA 815-R-06-007. This standard requires a three log (99.9%) reduction of Cryptosporidium oocysts, based on the theory of reducing to a concentration of one oocyst per 100 ml (average volume of water swallowed by a swimmer). An ISO 9000:2000 accreditation or NSF Standard 50 listing are both acceptable for validation.
(4) Do not use stabilized chlorine for disinfection.
(F) Filter the recirculated water. The design shall provide a separate filter for the interactive play attraction. Do not use the same filter serving a pool or other water recreation facility to also filter the water from an interactive water fountain. Shared filters could spread contamination to all pools and fountains on the same system. Also, other water venues may not be set up to disinfect at the high levels required for water from an interactive play attraction. A turnover rate of 0.5 hours is required per Rule 675 IAC 20-5-14(b), for interactive play attractions constructed, rehabilitated or altered after August 7, 2013.
(G) Both the design and operational procedures shall assure that trip hazards are prevented.
(H) Any grates on the deck pad must be kept secured and in good repair.
(I) Flush any materials or contaminants off the surface of the spray pad daily prior to opening. Clean more thoroughly, if necessary. Both the design and the operational procedures should assure that the water used for pre-opening cleaning is discharged to waste.
(J) Bathrooms, with diaper changing areas must be provided, and be located to assure easy access. Bathroom breaks should be encouraged. The required number of plumbing facilities is listed in Rule 675 IAC 20-5-25, for interactive play attractions constructed, rehabilitated or altered after August 7, 2013.
(K) Drinking fountains must be provided, and be located to assure easy access as required in Rule 675 IAC 20-5-25(e), for interactive play attractions constructed, rehabilitated or altered after August 7, 2013. Easily accessible sources of safe drinking water will discourage drinking of water from the interactive play attraction.
(L) The following signs shall be posted:
(1) Do not use if you had diarrhea within the last two weeks;
(2) No pets allowed;
(3) No glass or sharp objects are allowed on the spray pad;
(4) Do not drink the water; and
(5) Children who are not toilet trained must use swim diapers covered by rubber pants with tight fitting elastic at the waist and legs.
(M) In case of a fecal accident, the fecal accident procedure outlined in swimming pool rule 410 IAC 6-2.1 should be utilized.
(N) Overhead electrical wires shall be located at least 20 feet away from any spray pad, measured horizontally. Also, there should be no unprotected electrical circuits or wiring within ten feet of any spray pad.
(O) To prevent injury to patrons, unless certified by a feature designer and/or manufacturer, the water spray from a feature nozzle shall not exceed a height of six feet and not exceed a flow rate of 20 psi.
