    PUBLIC SWIMMING BATHS The baths provision consists of 4 swimming pools, 19 private bath¬ rooms and 1 vapour suite. The 4 swimming pools contain a total of 270,000 gallons of water and are filled from the town’s domestic supply, details of which have been given in the previous section. The water in the swimming pools is treated by continuous filtration. Water from the deep end of the pool is drawn by a pump through a strainer and, after the addition of coagulants to flocculate organic matter and to ensure efficient filtration, the water is pumped to the top of the filter units. The filter units comprise 4 x 10’ 0 diameter vertical cylinders containing sand and a system of collecting pipes in the bottoms which discharge the water after it has filtered through the sand. The water is then aerated, re-heated and chlorinated before being returned to the shallow end of the pool. The sand in the filters is washed when necessary by reversing the flow of water which runs to waste during the process. To secure efficient filtration coagulants in the form of sulphate of alumina and sodium carbonate are added to the water. Break point chlorination is used continuously, the chlorination being applied in the form of chlorine gas. The frequency of change of water in the pool is five hours. At all times it is aimed to maintain in the swimming pool water sufficient free and available chlorine to meet any possible pollution, a pH value of 7.5 to 7.6, and a residual alkalinity of not less than 200 ppm. The standards have at all times on examination been in accordance with those recommended in Report No. 71 of 1956 concerning the bacterio¬ logical examination of water supplies.
