The Globe. TUESDAY, NOVEMBER 28, 1876.

The citizens will we are sure cordially join with the Drainage Board in expressing satisfaction at the very complete plan of drainage proposed by Mr Carruthers. The drainage of Christ* church from its situation, presents many engineering difficulties, but it is matter for congratulation that at last we have before .us a practical scheme for carrying out this very necessary work. The salient points of the scheme were laid before the Drainage Board yesterday at its meeting. There are of course a number of details yet to be arranged, but now that the main features of the scheme have been settledn, no delay need take place in commencing. The district which may be called the sewerage district, and which will be drained [by the sewer system proposed by Mr Curruthers is divided into four sections. These are respectively the north, running as far as St Albans lane; the south to the southern branch of Jackson's Creek ; the next to the Lincoln road, taking in Addington and Waltham, and the east to the Stanmore road. It will thus be seen that a very large area, indeed nearly the whole of the thickly populated portions of the city and suburbs, will] be drained. The drainage of the portions of the district lying west of Colombo street and south of the Avon, will be conveyed to the present outfall drain by natural gravitation, the natural formation of this portion enabling this to be done. The district north of Tuam street and the Avon, and south of the river, will require to be drained by a system of sewers. These will convey the sewage to the junction of the East Belt and Kilmore street, where a storm overflow will allow the accumulated water, in case of flood, to flow'into the river. At this point, at which the sewage of the district referred to is concentrated by means of the sewers, a pumping station will be fixed. The sewage will then be lifted to a high level sewer passing along the East Belt to the existing outfall drain, and thence away to the estuary. The Southern and South-Western parts, including Waltham, Phillipstown, and the lowlying lands by the railway, will be drained by another sewer along the Ferry road, which is now in course of construction. This will go as far as Christchurch Quay, where, as in the case of the Avon, a storm overflow will be provided. The sewage will be pumped into a cross sewer communi-

eating with the outfall drain, and by this means it will be conveyed to the estuary. The great feature about Mr Carruthers' plan is, that the waters of the river are not contaminated by sewage. That is all deposited at the estuary, and the only water going into the river will be as now, the storm overflow. Mr Carruthers' scheme also includes a provision for dealing with the sewage when, as the city increases in population, the accumulation of it at the estuary is likely to prove offensive, which we are afraid will soon occur. The present outfall drain, under these circumstances, will be used for storm overflow drainage alone. The sewage will be collected at the Ferry road pumping station, and there deodorised. Altogether the scheme is one which appears to be thoroughly well considered, and we trust that no unnecessary delay will be allowed to occur before the Board commences operations towards its practical completion. Good and sufficient drainage has been the crying want of Christchurch for some years, and now that we have got a scheme which promises to meet all our requirements, it behoves the Board to forward the works connected with it as speedily as possible. We feel sure that the Board have a keen sense of their responsibility to the citizens in this matter, and that now measures will at once be taken to carry Mr. Carruthers' scheme into effect with as little delay as possible.
