The amount of crude sewage discharged into the Lough at Belfast is enormous, and discolours the water of the Lough for a very considerable distance from the outfall. The sewage is, however, only discharged on first half of ebb tides, when there is a great expanse of water at the outfall and in the Lough. Notwithstanding this, however, I consider that the shell-fish in the vicinity of the outfall, particularly the mussel and cockle strands opposite Greencastle on the northern side, and Tillysburn on the southern side of the Lough, are subject to gross contamination, and, to a lesser extent, the oyster beds in the Lough over which the sewage effluent passes, but in a varying degree, according to the distance from the outfall, and the consequent dilution of the effluent. Carrickfergus, having a population of 4,208, is drained to a considerable extent on the water carriage system. The crude sewage is discharged by two principal outfalls opposite the town at low water mark direct into Belfast Lough, within about half a mile of the cockle strand and one mile of the nearest point of an oyster bed, both of which I consider must to some extent be affected thereby. Bangor, with a normal population of 5,903, discharges its sewage by two principal outfalls, to the east of the town, directly into the Lough without any previous treatment. The town is drained almost entirely on the water carriage system; the consequent pollution must be very considerable, and would be likely to affect the oyster beds in the vicinity. Holywood, with a population of about 4,000, is drained directly into the Lough by three principal sewer outfalls. The town is drained on the water carriage system almost entirely, and the sewage is discharged in its...
