The total number of bathers using a swimming pool during
any period of time shall not exceed twenty persons for each
one thousand gallons of clean water added to the pool during
that period. The term "clean water," as used above, may be
interpreted to mean new clean water used to refill the pool,
new clean water used to replace loss by splashing or during
cleansing, water taken from the pool and returned after effective
filtration or any combination of such waters. (Code 1959,
§ 31-28.)
