The drainage of {{convert|2500|acre|ha|0}} of land around Tattershall was authorised in 1796, and came under the control of the Witham Third District commissioners in 1844[1] The building dates to 1856 when a rotative beam engine was built to replace windmill style engines possibly dating to 1540 and draining land between the rivers Bain and Witham.[2] The engine discharged into the River Witham,[3] but has a long fetch from a drain parallel to the river called The Dogdyke engine drain originating just south of Kirkstead at a place called Parkbeck.[4] 1856 is relatively late and Wheeler does say that the 1856 engine replaces one installed in 1841,[1] but the location of that is unknown. The building is a grade II listed ancient monument.[5] Engines
Steam engineThe steam engine is maintained by a preservation trust, and steamed on weekends throughout the summer.[6] Although the Pinchbeck Engine is older, it can no longer be steamed. The preservation trust claim this is the oldest working steam drainage engine.[6] The engine built by Bradley & Craven Ltd of Wakefield has a {{convert|16|foot|m|1}} flywheel, and a cylinder of {{convert|24|in|m|2}} diameter and {{convert|48|in|m|1}} stroke. [3] The construction is similar to an 'A' frame, but the decorative form of the cast iron upright obscures that basic shape and might be considered unique. The scoop wheel is {{convert|24|ft|m|1}} in diameter and runs at up to 7rpm through a 4:1 gearbox from the engine.[3] The first boiler, which lasted until 1909, was a twin tube Cornish type, working at 12psi. The replacement was a Lancashire boiler made by Fosters of Lincoln, delivering 15psi. Although the structure of this boiler survives, its rear end has been removed to make room for a modern vertical boiler which is used for the demonstration steamings.[3] The original {{convert|100|ft|m|0}} Chimney was struck by lightning in 1922 and reduced somewhat. It was felled in 1941 after the conversion to diesel operation.[3] Diesel enginesThe two diesel engines are maintained by The Witham Third District Internal Drainage Board as a standby for the nearby electric pumping station. They are usually operated when the museum is open.[6] The steam engine was replaced in 1940 by a Ruston & Hornsby 7XHR diesel engine, serial number 194833, driving a 22 inch Gwynnes centrifugal pump.[3] This engine has a capacity of 23.6 litre.[6] The 7XHR design has a single horizontal cylinder of {{convert|10|in|cm|1}} bore, {{convert|18.5|in|cm|1}} stroke, and develops {{convert|40|hp|kW|0}} at 300rpm.[7] There is also a Ruston & Hornsby 1VTO auxiliary engine, used to provide the starting air for the larger engine and to operate a small priming pump for the Gwynnes Limited pump.[6] The 1VTO design has a single horizontal cylinder of {{convert|4|in|cm|1}} bore, {{convert|4|in|cm|1}} stroke, and develops {{convert|5|hp|kW|0}} at 1000rpm.[7] Public accessAccess to the site on steaming days involves driving down an unmade road and walking across a grassed area. Although essentially on one level, disabled access is limited because of the historic nature of the site.[6] Toilets, teas and limited wheelchair access are offered.[8] See also
