(1) For the purpose of computing bather load capacity, those portions of the swimming pool five feet or less in depth shall be designated as "non-swimmer" areas. Portions of the pool over five feet in depth shall be designated as the "swimming" area.
(2) In order to compute swimmer and bather capacity, swimming and wading pool areas shall be determined as follows:
(a) 15 square feet of pool water surface area shall be provided in the non-swimmer area for each non-swimmer expected at time of maximum load.
(b) 20 square feet shall be provided in the swimming area for each swimmer expected at time of maximum load.
(c) 300 square feet of pool water surface area shall be reserved around each diving board or diving platform and this area shall not be included in computing the area of the swimming area.
(d) 100 square feet of pool water surface area shall be reserved around each slide and this area shall not be included in computing the area of the swimming area.
(e) The bather load capacity shall be stated on the permit. (see 105 CMR 435.21(1)).
￼￼￼(3) The Board of Health may make additional allowance for bathers in cases of swimming pools with extensive deck areas used by patrons for lounging or sunbathing. These allowances shall be based on studies of actual swimming pool use in areas within the jurisdiction of the Board of Health.
(4) Ten square feet of water surface area per bather shall be used in computing the bather load capacity for special purpose pools.
