The Welland & Deepings Internal Drainage Board was formed in 1973 by the amalgamation of four adjoining Boards: Deeping Fen Spalding & Pinchbeck, Maxey, North Welland and Baston Langtoft & the Deepings. The Board is an autonomous public body under the direct control of its Board members.
The Board is one of some 120 which are established in low lying areas of England and Wales such as the Fens, Somerset Levels, Kent Marshes and parts of Yorkshire. The functions and powers of Boards are defined by the Land Drainage Act 1991 and the Flood and Water Management Act 2010.
The Board’s area covers approximately 35,000 hectares and extends from just north of Peterborough to just south of Boston. Within their area the Board manage 14 pumping stations, 3 tidal sluices, 70 water level control structures and over 660km of open watercourses and surface water sewers.
