§ Mr. Beggs
To ask the Secretary of State for Northern Ireland whether contaminated filter sludge from reservoirs is being regularly dumped into rivers; if such dumping requires the approval of the Department of Environment (Northern Ireland); and where contaminated sludge from Killylane reservoir is dumped.
§ Mr. Tim Smith
It is not the practice of the Department of the Environment to discharge filter sludges produced as part of the water treatment process to rivers. Sludge from Killylane water treatment works is spread on land within the catchment area above the reservoir.
