Regualtion 61-51. Section C. Item 31.
31. Electrical and Illumination Requirements. Artificial lighting must be provided at all public swimming pools which are to be used at night or which do not have adequate natural lighting so that all portions of the pool, including the bottom, may be readily seen without glare.
(a) Underwater Lighting. Where underwater lighting is used, not less than 0.5 watts of incandescent lighting or 8.35 lumens must be provided per square foot of pool area. An adequate number of lights must be used and properly positioned so that all portions of the pool are clearly visible to an observer on the pool deck. Fiberoptic lighting may only be installed as a supplement to the minimum lighting requirements outlined above. Colored lights that do not provide for an equivalent light output to the wattage or lumens noted above for clear lights cannot be used.
(b) Area Lighting. Where underwater lighting is used, uniform area lighting must be provided for the deck area and directed toward the deck area and away from the pool surface insofar as practical. Illumination of the pool deck surface must be at least ten (10) foot candles of intensity, or not less than 0.6 watts of incandescent light or 10 lumens per square foot. Where underwater lighting is not used and night swimming is permitted, uniform area lighting must be provided in an amount of not less than thirty-two (32) foot candles of intensity, or not less than two 2 watts of incandescent light or 33.5 lumens per square foot of pool area in addition to 0.6 watts of incandescent light or ten (10) foot candles of intensity per square foot of deck area. These lights must be placed around the pool area such that all sections and depths of the pool are clearly visible at all times. Light fixtures located within the pool area must be protected by a non-breakable lens.
(c) Overhead Conductors, Wiring and Lights.
(i) Overhead conductors and wiring not in conduit must not pass within an area extending a distance of twenty (20) feet horizontally away from the inside edge of the pool walls, diving structures, observation stands, towers, or platforms. No pool can be constructed under an existing utility owned supply conductor in accordance with the current edition of the National Electrical Safety Code.
(ii) There shall be no light fixtures or conductor splices directly above the water surface at any outdoor pool. Indoor pools must comply with the same restriction except that light fixtures protected by a non-breakable lens are allowed.
(d) Wiring and grounding for lights and all electrical power for swimming pool equipment must conform to the codes of the current edition of the National Fire Protection Association (NFPA) National Electric Code. All electrical circuits within the pool area including all accessory equipment, electric drinking water fountains, and bathhouse/minimum toilet facility receptacles are required to meet the current edition of the NFPA National Electric Code; provided, however, all such circuits shall have ground fault protection regardless of their proximity to the pool. Exceptions may be granted for lighting and fixtures that are twenty-five (25) feet or more above the pool deck and would not pose a risk of electrocution. Junction boxes must be above the pool water level and must not be a trip hazard.
If your facility would like to become permitted for night swimming the Department would require the submission of a change order request form (attached) and an area lighting plan showing the lights on site and the illumination provided by them so that we may review it for compliance with the above portion of the regulations. Once approved and the lights are installed the permit will be amended to show that night swimming is permitted and as long as the lights are on the pool may remain open at night.
