The Reservoirs Act places a duty on the owners of reservoirs containing more than 25,000 cubic metres of water, that are raised above the natural ground level by the construction of a dam to comply with a regime of maintenance safeguarding against failure.

The council owns two reservoirs that fall within the provisions of the Reservoirs Act; Doffcocker Lodge and Mortfield Lodge. The Drainage Team regularly inspects and monitors the lodges and ensures that they receive annual inspections by a qualified reservoir engineer.
