The Doncaster East Internal Drainage Board was formed in April 2012 by a Constitution Order under the Land Drainage Act 1991 (as amended) following amalgamation of the Ashfields & West Moor IDB, Armthorpe IDB, Finningley IDB, Corporation of the Level of Hatfield Chase IDB, Potteric Carr IDB, Tickhill IDB and Tween Bridge IDB. The Board’s purpose is to protect people and their property against river and surface water flooding through water level management within low lying areas predominately from the east of Doncaster towards the River Idle and River Torne which discharge into the River Trent.
The Doncaster East Internal Drainage Board covers an area of 22,390 hectares and maintains 290km of watercourse and 24 pumping stations.
Up to 70% of the Drainage District relies upon mechanical means of lifting water from the low-lying areas into the River Idle, River Torne, Diggin Dyke, Hatfield Waste Drain, North Engine Drain, Day Brook, Torne Soak Drain, and Snow Sewer with gravity discharge dependant on Main River catchment rainfall, topographic levels, and/or tidal influences.
Within the District there are a number of pumping stations lifting water from subsided ground, inherited from the National Coal Board coal mining operations, whose impact on drainage is now managed by the Coal Authority. Coal mining and land drainage have a long-standing tradition and relationship dating back to 1913 which continues with private mining companies, licensed by the Coal Authority, to this day.
