The approved sanitation of swimming pools requires attention to certain details of construction, treatment of water used and regulations for the bathers entering the pool. Pools constructed with smooth or glazed walls and rounded corners lend themselves to easy cleansing. An overflow gutter about the edge serves to skim off floating débris and acts as a cuspidor for the bathers. The desire for some active disinfectant within the water itself has made the addition of chemical substances more popular than either ozone or ultraviolet ray treatment, both of which sterlize the water outside the pool. Chlorin is the disinfectant of choice because of its ease of application, either as chlorinated lime or as liquid chlorin, because of its high germicidal property and its low cost. Bathers are usually required to take a complete shower bath with soap before entering the pool, and those suffering from any infectious disease are excluded.
