The Building Commissioner shall not issue a permit to construct any family swimming pool or any alteration, addition, remodeling or other improvement thereto, unless the following design and construction requirements are observed. Within one year of the effective date of this section every existing family swimming pool shall be in conformance to the provisions of this chapter. Family swimming pools shall be constructed and maintained in conformity with the following requirements:
(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 Building Commissioner.
(c) Water Supply and 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 floor rim of the pool, or shall be provided with a vacuum brake 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, except that a walkway may be reduced to a minimum of three feet on any side of the pool that has a fence immediately adjacent thereto.
(e) Water in Pool. The water in the pool shall be from the City water supply.
(f) Recirculation. For new pools provision 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. The installation of new pools of the "fill and draw" type shall not be permitted. A satisfactory recirculating system for the pool shall be installed consisting of filters, circulating pumps, float valve control on water supply, hair and lint catcher, piping connections to inlets and outlets, backflow protection and all other necessary fixtures and connections. All equipment must be readily accessible and every pool shall be provided with necessary equipment for the measurement of acidity or alkalinity and for residual determinations.
(g) Indicating, Recording, Totalizing Instruments, Etc. When necessary, in the opinion of the Building Commissioner indicating, recording and totalizing instruments, flow-meters or indicators and pressure gauges shall be installed at such points as may be designated by the Building Commissioner
(h) Hose. Hose connections and hoses must be of ample size and pressure to clean all of the pool area.
(i) Towers and Steps. Steps and ladders must be made of an impervious, corrosion resistant material, with a uniform rise not to exceed twelve 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.
(j) Lighting. Where a family pool is used during the hours of darkness, illumination of the pool surface, and for a distance of ten 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" or equivalently approved.
