Water Supply, Rawmarsh Mr. Hardy asked the Secretary of State for the Environment if, when he next meets the chairman of the Yorkshire water authority, he will discuss the level of water supply in parts of Rawmarsh. Mr. Macfarlane The day-to-day management of the supply and distribution system is the responsibility of the water authority, to which any questions should be referred. Mr. Hardy asked the Secretary of State for the Environment (1) what is the nature of the contamination of Roundwood brook in Rawmarsh in the Wentworth constituency;(2) if, when he next meets the chairman of the Yorkshire water authority, he will discuss with him the problem and the nuisance arising from the contaminated condition of Roundwood brook in Rawmarsh near Rotherham;(3) if, when he next meets the chairman of the Yorkshire water authority, he will discuss the sewerage arrangements in the Walker street and Claypit lane areas of Rawmarsh near Rotherham. Mr. Macfarlane The contamination of the Roundwood brook is due to occasional discharges of sewerage effluent in periods of heavy rainfall which can overload the sewer capacity. The Yorkshire water authority has planned a major project to improve the situation.This is a local problem and is therefore appropriate for discussion and consultation at that level.
