No.Nome of town or district.Remarks.
31MiddletonIf sufficient area of beds is employed and they are properly managed the treatment is satisfactory. It is contemplated treating the whole of the sewage by the bacterial process.
32NelsonResults obtained by experimental beds are quite satisfactory.
33OldhamAverage daily flow of sewage (1900) 4,000,000 gallons. Experiments show that bacteria beds should be supplied with a tank effluent of uniform strength. Chemicals are an unnecessary expense and rather hinder the work of the bacteria beds than assist it. It is intended to treat the Oldham sewage by subsidence followed by the action of bacteria beds. There is a greater uniformity in the strength of the effluent from the septic tank than in that from the sedimentation tanks, and the bacteria beds act better when an effluent of uniform strength is used, and the effluent from the septic tank and bacteria beds seldom putrifies on incubation. There is also a very considerable reduction in the quantity of sludge.
34OrmskirkThe results obtained at the farm of the Urban District Council of Ormskirk by passing the sewage through lagoons, into settling tanks, over the land and through the coke breeze filter beds successively, are very satisfactory and meet the requirements of the authorities (no chemicals are used).
35OswestrySmall experimental beds were originally constructed. Later, beds for the treatment of the whole of the sewage. There is no doubt as to the success of the bacterial treatment, our results are continuously satisfactory and the effluents keep free from putrescence. Probably a small amount of septic action takes place in the settling tanks.
