Pumping out the challenges

摘要

Stillingfleet water pumping station was originally constructed by British Coal in the early 1990s when mining subsidence lowered the ground level and prevented water in this low-lying area draining away by gravity into the nearby beck. Now the responsibility of Ouse & Derwent Drainage Board, the facility has had two new submersible Bedford pumps installed while two pumpsets that had been removed from service have been overhauled. The work has been carried out by AxFlow. Mark Redgrove, AxFlow's technical support manager, explains: "Earlier this year the drainage board detected that the moisture readings within the pump linings were a cause for concern. "Although the pumping station is equipped with two 800mm rising main storm and two 600mm rising main dry weather pumps, the drainage board recognised that they could not be two pumps down for a prolonged period so two new submersible Bedford pumps were ordered. We were called to remove the old Bedford SB pumps and install the new pumps."
