A. 
General.
(1) 
No swimming pool greater than three feet in depth of water or appurtenance thereto shall be constructed, installed, enlarged or altered until a permit has been obtained form the Building Official. The approval of all city and state authorities having jurisdiction over pools shall be obtained before applying to the Building Official for a permit. Certified copies of these approvals shall be filed as a part of the supporting data for the application for the permit. In the event of any conflict between the provisions of these regulations and any provision of state law or requirement, rules or regulations of the State Department of Public Health, the provision imposing the higher standard or the more stringent requirement shall have precedence.
(2) 
Before any permit for a swimming pool is issued, plans, including a site plan with elevations, shall be submitted showing accurate dimensions and construction of the pool and appurtenances, properly established distances to lot lines and details of water supply, drainage and water disposal systems.
(3) 
A private swimming pool may be constructed in any zone as an accessory use to a residential use.
(4) 
Any swimming pool and appurtenances shall conform to the same yard and coverage requirements for buildings as set forth for each zone and shall conform to the standards for walls and fences set forth in these regulations.
B. 
Water supply and drainage system.
(1) 
No direct mechanical connection between a source of domestic water supply shall be made to a swimming pool or to the piping to the pool. The water supply for filling the pool, when derived from a potable supply, shall be by means of an over-fall fillspout to the pool or an over-fall supply to a surge tank, wherein the water will freely overflow at deck level or the top of the surge tank before coming into contact with the water supply outlet.
(2) 
The swimming pool and equipment shall be equipped to be completely emptied of water, and the discharged water shall be disposed of in an approved manner that will not create a nuisance to the adjoining property. Whenever any waste or drainage from a swimming pool is connected to a sanitary sewer or storm sewer, an air-gap or a relief manhole shall be provided which will positively preclude against surge or back flow introducing contaminated water into the swimming pool or water treatment plant. The written permission of the public authority having control of such sanitary or storm sewer shall be filed with the application for a permit.
C. 
Safety precautions.
(1) 
No electrical wiring shall be permitted to pass overhead within 20 feet of the swimming pool enclosure.
(2) 
There shall be an adequate enclosure either surrounding the property or the swimming pool area, which shall be sufficient to make the pool inaccessible to small children. Such enclosure, including gates, must not be less than four feet above grade. All gates must be self-latching with latches placed at least four feet above the ground or otherwise made inaccessible from the outside to small children. A natural barrier, building, hedge, pool cover or other protective device approved by the Building Official may be used if the degree of protection afforded by the substituted device or structure is not less than the protection afforded by the enclosure, gate and latch described herein.
