The Reservoirs Act ensures that the owners of reservoirs containing more than 25,000 cubic metres of water, that are raised above ground level by a dam, keep these reservoirs well maintained, safeguarding against failure.
Other large reservoirs in Bolton are owned and maintained either privately or by United Utilities. If you have any concerns or queries on any of these, contact the Environment Agency on 03708 506 506.
