The Pinchbeck Engine served an area around Pinchbeck and Spalding which has been embanked and drained since Anglo-Saxons settled in the area. A series of sea-banks can be dated back to this time. The settlement of Pinchbeck was well established by the time of the Norman conquest and appears in the Doomsday book of 1086. It was a growing settlement with many small ‘manors’ which expanded as more land was successfully drained. The Pinchbeck Engine is a restored beam engine, an impressive reminder of the time when man relied on the power of steam to drain the land. The Pinchbeck Engine was built in 1833 and is a 20 horse-power A-frame low pressure condensing beam engine. Each year the Pinchbeck Pumping Engine lifted an average of 3,000,000 tons of water from the land at a rate of 7,500 gallons per minute. As drainage technology progressed steam powered drainage engines were replaced with diesel engines, and then with electricity powered pumps. Diesel engines were never introduced on this site. The Pinchbeck Engine has survived in such fantastic condition because the transition, in 1952, from steam power to electricity was direct.
