Swimming Pool Codes - City of Fargo

CHAPTER 7 - SPECIAL POOLS7.1 WADING POOLSA wading pool is a small pool for non-swimming children only and shall have a maximumdepth at the deepest point not greater than 18 inches. It shall be constructed adjacent to theswimming pool and shall be separated from it by a fence or partition sufficiently high toprevent waders from entering the swimming pool area.The water supply to the wading pool shall be filtered and chlorinated from its own separatere-circulation system or from the swimming pool re-circulation system. The outlets from thewading pool may be wasted or returned to the re-circulation system. Due to the high degreeof pollution, a wading pool shall have a maximum turnover rate of 1 hour.Wading pools work best when filled with treated water from the pool re-circulation systemand drained away through a constant level overflow. Additional chlorine may have to beadded to maintain an adequate residual. The pool shall be drained, cleaned, and refilled withfiltered and chlorinated water daily.It may be desirable to install a spray pool in lieu of a wading pool so that no water stands atany time, but is drained away as it sprays over the area.7.2 SPASTherapeutic, hydrotherapy, spa, or hot tub pools are small heated pools with roiling water,intended to be used exclusively for relaxation rather than swimming or exercise. Whirlpoolsalso provide this water action, but are usually unheated.Spas may be constructed of concrete, gunite, or fiberglass. Gunite or concrete are used mostoften when the spa is built as part of, or in conjunction with, a swimming pool built of thesame materials. Prefabricated fiberglass spas are manufactured in a wide variety of sizes anddesigns. They have molded benches, lounges, and hammocks to allow comfortable seatingor reclining. Coated with an extremely smooth gel coat finish, they can resist attacks of algaeand clean easily.The spa, or therapeutic action, derives from the warm temperature of the water and roilingaction created by the injection of air. Hydrotherapy heads or an air pump createshydrotherapy action. Hydrotherapy heads use a centrifugal pump to force water through aconstriction located in the head. An air tube connected to the throat of this constrictionprovides air and the mixture of air and water is forced out through a wall fitting into the pool.This velocity mixture of air and water provides a true massaging action.Air blowers introduce air directly into the water through hundreds of small holes built intothe pool. The roiling action provided by the blower is considerably greater than possiblewith a hydrotherapy head, but it lacks the forceful massaging action that the heads provide.30
