This steam engine was built by Hathorn Davey & Co. in Leeds and installed at the Pumping Station in 1894, along with the North engine. The two engines are almost identical and were run one at a time for a period of up to two weeks. They were fueled by the historic boilers and pumped sewage from Cambridge to the sewage farm at Milton. The engines run at up to 14 strokes a minute and are 80 horse power. The Hathorn Davey engines are unique because they are the only working engines of their type left in the world.
