Steam engine

The steam engine is maintained by a preservation trust, and steamed on weekends throughout the summer. Although the Pinchbeck Engine

 is older, it can no longer be steamed. The preservation trust claim this is the oldest working steam drainage engine.

The engine built by Bradley & Craven of Wakefield has a 16 feet (4.9 m) flywheel, and a cylinder of 24 inch (0.6096 m) diameter and 48 inches (1.2 m) stroke. 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 24 feet (7.3 m) in diameter and runs at up to 7rpm through a 4:1 gearbox from the engine.

The first boiler, which lasted until 1909, was a twin tube Cornish type, at 12psi. The replacement was a Foster locomotive-style tubed boiler delivering 15psi. Although the structure of this boiler survives, a modern vertical boiler is used for the demonstration steamings.

The original 100 feet (30 m) Chimney was struck by lightning in 1922 and reduced somewhat. It was felled in 1941 after the conversion to diesel operation.

Diesel engines

The 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.

The steam engine was replaced in 1940 by a Ruston & Hornsby 7XHR diesel engine, serial number 194833, driving a 22 inch Gwynnes centrifugal pump. This engine has a capacity of 23.6 litre. The 7XHR design has a single horizontal cylinder of 10 inches (25.4 cm) bore, 18.5 inches (47 cm) stroke, and develops 40 hp at 300rpm.

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 pump. The 1VTO design has a single horizontal cylinder of 4 inches (10.2 cm) bore, 4 inches (10.2 cm) stroke, and develops 5 hp at 1000rpm.

Public access

Access 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.

Toilets, teas and limited wheelchair access are offered.
