Bedford Pumps, a UK manufacturer of large submersible and conventional pumps for the land drainage industry, has recently installed and commissioned a direct drive variant of its fish friendly pumps for Cam pumping station in the South Level Cambridgeshire Fens, UK.

The UK's Fenland area is comprised of mainly high grade agricultural land, much of which is below sea level, considerably below flood level, and therefore totally dependent on pumped drainage. Cam pumping atation is one of three stations within the district and part of a 7,000 acre (2857 ha) pumped catchment, managed by Waterbeach Level Internal Drainage Board.

Cam pumping Station, located close to the village of Streatham, discharges directly into the River Cam. The pumping station had been operating with a combination of old diesel driven and one electric pump, but with a requirement for the pumps to be upgraded combined with new legislation requiring that measures be put into place to reduce eel mortality at pumping stations, the decision was made to install two new pumps from Bedford’s Fish Friendly range.

Bedford Pumps manufactured, installed and commissioned two DAF (Fish Friendly Direct Drive Axial Flow) pumps for Cam pumping station through consultants Hannah Reed. The pumps have been installed in a vertical suspended position with below floor discharge, in a new sump on the existing site. The pumps are powered by electric motor through a gearbox with an external PTO facility. This offers the ability to drive the pump by tractor in the event of a power failure. Each pumpset will discharge 1,150 l/s at 5.6 m head.

In addition to the pumps, Bedford Pumps also supplied Siphon Breaker Valves and Sub Bellmouth Flow Splitters for the units. They also undertook the M & E works for the site, taking out the old control panel and replacing it with a new Motor Control Centre. This will operate both the new pumps and an existing pump, which was retained as a stand-by.
