    Seimra(fe and disposal of sewape,—Since Dr. Wheaton’s report, inquiries have been held ])v the Board’s Engineering Inspectors, viz. :—by Col. Durnford in 1906 and Mr. Brightmore in 1907, respecting applications for sanction to borrow money for the above purposes, and in June 1909, sanctions were given by the Board for sums amounting to £32,400. As the scheme is in course of being carried out, subject to certain amended plans being approved by the Board, I will content myself with briefly setting out the main points in the new scheme, which has been hastened by the Derbyshire County Council obtaining an Order of Court forbidding- pollution of the River Erewash by Ilkeston sewage after a certain date. A new intercepting sewer, 3^- miles long, is being constructed, and a new sewer for the west and south of the borough. These are to deliver sewage on to an area of 33 acres, where it will be treated in a screening tank, and then in septic tanks (holding one day’s dry weather flow) and filter beds (taking three days’ dry weather flow). It is reckoned that 750,000 gallons a day will be treated. On account of the clayey nature of the subsoil, there will be no subsequent land treatment. To reach the disposal area, the sewage will have to be siphoned under the Erewash Canal and the adjacent Midland Railway Company’s land. The new intercepting sewer is to take the place of the present high level and middle level sewers, which deliver sewage at the southern outfall of the low level sewer at Oallow^’s Inn. The sewage farm (39 acres) here has been raised above flood level, and will be used when required. The Ives’ tanks at this outfall and at the Botany Bay (north outfall) and Potter’s lock (central outfall) will be diverted from their former use. Up to now they have been employed to precipitate the sewage with alumino-ferric, the effluent being discharged into the River Erewash, and the sludge pumped on to land. In future, they are to be used as storage tanks, and sewage is to be pumped from them to the new intercepting sewer, duplicate plant being laid down for the purpose. - The sewage farm (19 acres) at Potter’s Lock (central outfall) like that at Grallow’s Inn (south outfall) will be used when growing crops need irrigation. The farm (40 acres) at Hallam’s Fields, at the south-east of the borough, to which the high level outfall sewer for- merly discharged, is to be abandoned directly the new intercepting sewer is completed, the land having been sold to the Stanton Iron Company, the Board’s sanction not being required. This high-level sewer discharges at present into the mid-level sewer, and by it to the southern outfall; both will be replaced by the new intercepting sewer. The disposal works were in course of construction at my visit, and were apparently being carried out in accordance with the scheme sanctioned by the Board. The sewage farms at the central and southern outfalls appeared in satisfactory condition on the whole. When the proposed scheme is fully accomplished, the pollution of the river Erewash by Ilkeston sewage, to which the Board’s attention has been strongly directed by both Derbyshire and Nottinghamshire County Councils, will be greatly diminished. With respect to the condition of the present sewers, there is some deposit to be seen at cei*tain of the manholes : this may be largely due to subsidences from coal workings.
