An additional pump supplied by Cornwall Fire and Rescue Service is helping to contain minewater at Wheal Jane near Baldhu, Cornwall and reduce the risk of pollution in the nearby Carnon River and Fal estuary.
The pump was successfully lowered into a mine shaft last night (Wed).
Despite the extra help from the fire service, the water is still rising, but at a reduced rate and levels are being carefully monitored. The seven existing pumps are removing 375 litres per second from the mineshaft.
The Fire Service pump has boosted the volume to 450 litres per second. Rainfall has reduced and the outlook is calmer for the next few days.
In our role as regulator, we are continuing to work with the Coal Authority and the site operator as well as with all our other partner organisations to explore ways of alleviating the possible escape of untreated water from Wheal Jane.
