Section 61-51.E - DESIGN REQUIREMENTS FOR TYPE "C" POOLS

1. Applicability. Requirements of this section are applicable to all new construction and alterations of existing public swimming pools.

2. Type "C" Pools. In addition to meeting all other applicable requirements of these regulations as found in Section C, Type "C" pools must also meet the following:

(a) There must be a minimum of two (2) inlets and two (2) main drains and at least one (1) surface skimmer positioned and operated in accordance with R.61-51.C.26(b).

(b) When only one (1) skimmer is provided and the equalizer outlet is installed on the pool floor, it must be equipped with a minimum of two (2) interconnected suction fittings spaced at least twelve (12) inches apart. The interconnecting line must be sized to accommodate one hundred (100) percent of the recirculation flow.

(c) Main drains shall be located on the pool bottom floor.

(d) Inlets and outlets must be provided and arranged to produce complete recirculation of pool water and the maintenance of a uniform and adequate level of disinfecting medium at all times.

(e) A means of completely draining the contents of the pool to waste must be provided without passing through the filter. This may be done by a gravity waste line directly from the pool or by pumping and by-passing the filter.

(f) The maximum depth for a wading pool shall be eighteen (18) inches at the center. The bottom must have a maximum slope of no greater than five-eighths (5/8) inches per foot toward waste outlets or main drains. The depth at the perimeter may be zero (0) feet.

3. Spray Pools. In a spray pool, water must be designed to drain away freely as it sprays over the area. Water quality, wall and floor construction must meet the same requirements as set forth for public swimming pools. The bottom must have a minimum slope of not less than one-fourth (1/4) inch per foot (nor maximum of more than five-eights (5/8) inch per foot) toward waste outlets. All equipment drains, steps, gadgets, and toys must be installed per the manufacturer's recommendations.

4. Recirculation System. A recirculation system consisting of pumps, motors, piping, filters, inlets, outlets, disinfecting and other water conditioning equipment and necessary accessories must be provided for water purification in accordance with water quality criteria contained herein and must be designed to completely turnover the entire pool volume in one (1) hour. The recirculation system shall be designed to operate on a twenty-four (24) hour basis. The normal pattern of recirculation developed must be fifty (50) percent flow through the overflow or skimming facilities and fifty (50) percent through the main drains. The recirculation system must be designed with adequate capacity such that one hundred (100) percent of the recirculation flow can pass through the overflow or skimming facilities and one hundred (100) percent through the main drain.

5. Pool Deck. The pool deck must be constructed in accordance with Section C, Paragraph 6.

6. Sliding Boards. No sliding boards are allowed in any Type "C" pool.

7. Steps. If installed, one set of steps designed in accordance with Section C, Paragraph 35 shall be provided.

8. Fill Line. Kiddie pools may be filled by a hose bibb protected by an ASSE 1024 listed residential dual check or other Department approved backflow prevention device.

9. Automatic Controllers. All new Type "C" pools must be equipped with automatic controls to provide adequate feed rate of halogen and pH adjustment chemicals in order to keep the disinfectant and pH at the required levels on a continuous demand basis. A warning light or indicator shall be provided in a visible location for supervisory control. The device shall indicate absence of chemicals in feeders, improper adjustment of chemical dosage, or any other mechanical or operational malfunctions, e.g. recirculation flow stops.
