Quantity of Water Required.—The quantity of water required by towns for all purposes varies with circumstances, such as the general presence or absence of water-closets, manu- facturing processes, ko The average supply per head for the London districts in 1884 was 28 gallons in the 24 hours, varying from 25 to 37 gallons. Some towns exceed this amount, while others do not reach it; in Glasgow, for example, the daily supply is 50 gallons, while in Sheffield it is only 20. Dr. Parkes has calculated the amount used per head in a house- hold of fairly cleanly people at 12 gallons; in this calculation, 2| to 3 gallons are allowed for a daily sponge bath, and it includes clothes-, utensil-, and house-washing, but not a water- closet supply. The same writer states that if from scarcity of supply the amount must be limited, 4 gallons is the least that ought to be allowed, and that with this amount there cannot be daily washing of the whole body, and there must be insufficient change of underclothing. This question is of importance to Sanitary Authorities of rural districts in determining, for example, whether the yield of certain wells is sufficient. A double system of water-supply has been suggested ; pure for drinking and less pure for washing purposes in cases in which difficulty has been experienced in obtaining a sufficient supply of pure water for all purposes; but there are two objections to this plan—first, the cost in providing duplicate pipes, and second, the danger that, through carelessness, the one supply might be substituted for the other.
