Water levels warning issued as refurbished pumps are calibrated
Machinery at East Hull pumping station – which is vitally important to prevent flooding in Hull – is being tested as an 800,000 programme of refurbishment work draws to an end.
Water levels are set to go up in the Holderness Drain by about 1m as the four pumps in the station on Hedon Road are recalibrated.

Sensors upstream of the pumping station had been set much lower than usual to give operators early warning if there is a sudden influx of water into the system.
As well as the Holderness Drain, water levels may alter in Bransholme Great Culvert and Monk Dyke.
The pumps' electrics, motors and moving parts have been overhauled since January.

Yorkshire Water's pumps, which usually pump sewage, can be called upon in an emergency.
