    Report of Sanitary Inspector To the Chairman and Members of the Hale Urban District Council. Gentlemen, I beg to present my Annual Report for the year 1938. SANITARY CIRCUMSTANCES OF THE AREA. WATER SUPPLY. With the exception of a small number of houses in the added area of Ringway, which derive their water supply from wells, the whole of the urban district is served by the mains of the Manchester Corporation, and a constant supply of excellent quality is maintained. During the year one sample of water was taken for bacterio- logical and chemical examination and was reported satisfactory. RIVERS AND STREAMS. The River Bollin and the Timperley Brook pass along the southern and northern boundaries of the district. All water-courses in the area come under the surveillance of the Mersey and Irwell Joint Committee. DRAINAGE AND SEWERAGE. The district is drained on the separate system. The sewage from the southern area is treated at the Council’s sewage works, and a portion of the northern area is drained into the sewers of the adjoining Borough of Altrincham,. The Activated Sludge System is the method employed at the Council’s sewage works, and a satisfactory effluent has been maintained. Frequent samples were takert by the Inspectors of the Mersey and Irwell Joint Rivers Committee. The sewage is brought to the works by gravitation and op arrival passes through a preliminary tank, after which it is screened and passed through the detritus chambers. Thence over a rectangular weir it flows into the mixing chamber where it is intimately mixed with the sludge from the re-aeration tanks. The mixture then passes into the aeration units and from these flows to the settlement tanks. Here, the sludge settles to the bottom, leaving the clear effluent to pass into the feed channels and eventually into the River Bollin. The sludge is forced into a sludge channel which leads to the re-aeration tanks where, after a period of re-aeration, it again is mixed with the incoming sewage in the mixing chamber. Thus the continuous circulation is maintained.
