Water is supplied in the Borough of Slough by three water undertakings. The water to the main part of the town is supplied by the Slough Corpora¬ tion, the western ward of Burnham is supphed by the Burnham, Dorney and Hitcham Water Co., and water for the Trading Estate and a few surrounding houses comes from an independent borehole supply on the Estate. I propose to deal with these suppHes separately. Slough Corporation Water Supply. The water supply in the Slough water area, which includes a part of the surrounding rural district, was consistently satisfactory both in quality and quantity. 14,657 houses, with an estimated population of 63,025, are served by a direct supply and 136 houses, with an estimated population of 585, are supplied by standpipes. 12 samples were taken for bacteriological analysis at regular intervals during the year from the pumps at Pococks Lane Pump¬ ing Station, Datchet. Nine of these samples w'ere examined at the Council’s laboratory and three were examined by an independent consultant. All were of a high degree of purity, showing no traces of bacteriological contamination. No plumbo-solvent action has ever been noted. Burnham, Dorney and Hitcham Waterworks Co. L,td. The water supplied by this company to 2,602 houses, with a population of over 10,000, was consistently satisfactory in quantity and quality. Thirty-two bacteriological examinations were made during the year and all samples were free from contamination. In addition to this, six chemical analyses were made and although the water is hard, the hardness is not excessive. The result of a typical chemical analysis is set out below.
