The Building Commissioner shall not issue a permit to construct any swimming pool or any alteration, addition, remodeling or other improvement thereto, unless the following design and construction requirements are observed. Swimming pools shall be constructed and maintained in conformity with the following requirements. For pools already in existence, the Building Commissioner shall furnish the owners with a program of improvements and additions which shall be carried out over a period not to exceed ninety days after notice, in order to comply with the requirements of this chapter.
(a) Material. The water-containing surface of artificial pools shall be light in color, impervious and provide a tight tank with smooth and easily cleaned surfaces. Sand or dirt bottoms are prohibited.
(b) Depth Markings. Conspicuous markings shall be provided at regular intervals showing the depth of the pool. Special markings for large and odd-shaped pools shall be as prescribed by the Safety Director. This shall apply only to an underground pool.
(c) Water Supply Outlets. Each pool shall be equipped with water inlets and outlets of sufficient size and proper location to provide a uniform circulation of water in all parts of the pool. All water inlets shall be located not less than one foot above the flood rim of the pool, or shall be provided with a vacuum break sufficient in size to prevent backflow in the event of lowered pressure in the public water lines. All drainage of the pool shall be into a storm outlet only.
(d) Walkways. The pool shall be completely surrounded by a walkway at least four feet in width which shall be drained away from the pool. This shall apply only to an underground pool.
(e) Water in Pool. The water in the pool shall meet the requirements of the Board of Health for a safe drinking water supply.
(f) Recirculation. For new pools provisions shall be made for complete circulation of water through all parts of the pool. The system shall be equipped with a water recirculating system of sufficient capacity to provide a complete turnover of water at least once in eight hours.
(g) Indicating, Recording, Totalizing Instruments, etc. When necessary, in the opinion of the Building Commissioner, indicating, recording, totalizing, flow meters or indicators and pressure gauges shall be installed at such points as may be designated by the Building Commissioner.
(h) Hair and Lint Catchers. The pump suction line of the recirculating system shall be provided with a hair and lint catcher.
(i) Hose. Hose connections and hose must be of ample size and pressure to clean all of the pool area.
(j) Towers and Steps. Steps and ladders must be made of an impervious, corrosion resistant material, with a uniform rise not to exceed 12 inches. The decks of diving towers which are over one meter high shall be protected with suitable railings to prevent falling except into the water.
(k) Lighting. Where a swimming pool is used during the hours of darkness, illumination of the pool surface and for a distance of five feet from the edge of the pool shall be maintained between the limits of two and five foot-candles of light (approximately one-half watt per square foot of the area required to be illuminated, where lights are placed not over ten feet above and within the limits of the area). All lighting and wiring shall be in accordance with the National Electrical Code and all fixtures and equipment shall be "UL" approved. Lighting shall be so arranged and shaded as to reflect light away from adjoining premises.
