    SANITARY CIRCUMSTANCES OF THE AREA- SEWAGE DISPOSAL The following information has been supplied by Mr. James L. Hill, Borough Surveyor:— The Sewage is dealt with in four portions- (a) Houghside Sewage Works. The extensions commenced at this works in July, 1948, were completed in September, 1952, and the works now consist of automatic and hand screens with the disintegration of screenings, detritor fitted with mechanical grit remover, rectangular storm and precipitation tanks, circular humus tank, and twin- series centrifugal pumps for returning humus sludge to the works inlet. Milk of Lime and Alumino Ferric are used as precipitants and sludge is disposed of on drying beds. (b) Smaleweli Sewage Works consists of precipitation, storm and humus tanks, with filtration by percolating and land filters. Alumino ferric is used as a precipitant and sludge is disposed of on drying beds. Extensions are now being carried out with a view to (1) returning humus sludge to the works inlet and (2) affording facilities for a scheme of re-circulation of filter effluent: (c) Sewage from Farsley and (d) Calverley is treated at the Rodley works of the Leeds Corporation.
