These Regulations are promulgated under the authority granted to the Metropolitan Health Department of
Nashville and Davidson County under Chapter 10.48 Public Swimming Pools of the
Metropolitan Code of Law. These regulations establish guidelines for the
design, construction and operation of public swimming pools. They have the
force of law as authorized by Chapter10.48 and take effect immediately on
publication.
I. Design Detail and Structural Stability
1.1 All public pools shall be designed and constructed to withstand all anticipated loadings for both full and empty conditions.
1.2 No limits are specified for length or width of public pools. Consideration shall be given to shape from the standpoint of sanitation, safety and the need to facilitate supervision of bathers using the pool.
1.3 The shape of any public pool shall be such that the circulation of pool water and control of swimmer safety are not impaired.
1.4 A hydrostatic relief valve shall be provided in areas having a high water table. The designing architect or engineer shall be responsible for certifying to the structural stability and safety of the pool.
1.5
For design features not specifically
addressed in these regulations the Director of Health shall evaluate same and
approve or disapprove said features as appropriate.
2.1 The minimum size commercial pool constructed in Davidson County (with or without diving board) shall contain at least 860 square feet of water surface area.
2.2 In as much as effective operation, sanitation, and safety of pools are directly related to pool size and occupant loading the minimum size of 860 square feet of water surface area shall be provided for every 100 unit complex or less.
2.3 A complex (this includes apartments, condominiums, planned unit developments, hotels, motels, trailer spaces, individual residences, etc.) in excess of 100 units shall have additional pool area provided at the rate of a minimum of 215 square feet for every 25 units addition thereto.
Provided, however, the maximum size commercial pool required to be constructed by a large hotel
( a hotel with 1,000 rooms or
more adjacent to or operated in connection with exhibition hall space of at
least one hundred thousand square feet) located within a premier tourist
destination area (a geographical area of the metropolitan government that
contains a theme park, golf courses, water theme parks, entertainment complexes,
restaurants and other tourist-related activities and businesses) shall not
exceed a total 8,000 square feet of surface area, which can be contained in more
than one commercial pool.
III. Pool Construction Materials
3.1 All public pools and all appurtenances thereto shall be constructed of materials which are inert, non-toxic to man, impervious, permanent, enduring, which can withstand the design stresses, which will provide a tight tank with a smooth and easily cleaned surface, or to which a smooth easily cleaned surface finish can be applied, and which shall be finished in white or light color.
3.2 Pool bottoms of sand, fiberglass, earth or vinyl liners are not permitted in public pool construction. Consideration will be given to the use of fiberglass or acrylic whirlpool shells and fiberglass or PVC membrane swimming pool liners.
3.3 Pool finishes including bottom and sides, must be white or light colored material, non-toxic to man, with a smooth finished surface, without cracks or joints, bonded to the supporting members, excluding structural expansion joints.
3.4 Ceramic tile or other similar materials used as a slip resistant surface in or around public pools or appurtenances shall meet the following criteria:
(a) Finished surfaces are to be unglazed.
(b) Material is to meet any applicable manufacturer recommendations regarding suitability of the material for the intended application.
(c) A minimum static coefficient of friction rating, where applicable, of 0.6 wet, as determined by ASTM standard test method C-1028-84 is required.
(d) A sample of the proposed material, as requested, along with any supporting data is to be submitted to the Health Department for approval prior to the installation of the material.
(e) Any material to be used underwater to identify steps, benches, etc. in any public pool shall be of a permanent type and shall be of a color markedly contrasting to the pool interior finish.
(f) On new installations, the
alteration, modification or treatment of materials from the manufacturers
