e o AO, tc,, M I: Guidelines for Construction and Operation of Interactive Water Fountains Background Interactive water fountains typically consist of water spray or jet devices located in an area accessible to the public. They are intended to provide individuals with a means to play in the water without going into a swimming pool. These interactive water fountains are becoming very popular in settings around swimming pools and in nontraditional settings, such as outdoor malls and amusement parlts. In the recent past, interactive water fountains have been associated with the transmission of waterborne disease outbreaks of shigellosis and cryptospordiosis. The purpose of these guidelines is to clarify the requirements necessary to properly construct and operate interactive water fountains in a safe and sanitary manner. r Scope These guidelines apply only to interactive water fountains as defined below, regardless of where the attraction is located. Definition Interactive water fountains with recirculated water are .considered special purpose pools. Interactive water fountains are water features where interaction with the water by the public is encouraged and not discouraged. These type of pools are constructed and designed so that there is no accumulation or ponding of water on the surface of the ground. Water is stored in an undazground reservoir or surge chamber. Water is sprayed into the air through special nozzles. After the water hits the ground it drains back to the surge chamber. A recirculation system draws water from the surge chamber where it is filtered, disinfected and returned to the surge chamber. Requirements: 1. A plan review and approval is required by the Enforcing Agency prior to construction. 2. All parts of the interactive fountain must be designed, constructed, maintained and operated so there are no slip, trip or fall hazards or other conditions that may pose a safety hazard. 3. The splash zone must be properly sloped so that only water from the jet spfbys flows back to the surge tank. Areas adjacent to the splash zone must be sloped away from the collection drains. Plants or vegetation within the immediate area of the splash zone are prohibited. 4. There shall be no ponding of water within the splash zone. 5. The spray devices must be designed, constructed and installed so that they do not create a safety hazard. Nozzles that spray from the ground level must be flush with the ground, with openings no greater than one-half inch. Spray devices that extend above the ground must be high enough so they can be clearly seen and are not a trip hazard. 6. All foggers and jet nozzle sprays that produce finely atomized mists must be connected to a separate potable water source. 7. The recirculation system must be on a separate loop and not interconnected with the jet spray pump. The attraction pump(s) and recirculation pump must be electrically interconnected so
