A regional pumping system to control underground water levels is being established to prevent uncontrolled outbreaks of minewater in the East Fife Coalfield . The minewater is very acidic and heavily contaminated with metals.More Information >
Annesley / Bentinck, Nottinghamshire
The scheme comprises a series of aeration channels and sedimentation ponds constructed on a spoil heap to settle iron solids from around 100 litres/sec of minewater. An 18 km overland pipeline was designed and constructed to discharge directly to the River Trent to achieve sufficient dilution for the minewater. The pipeline included a crossing of the main Nottingham to London railway by auger-bore. More Information >

Woolley, West Yorkshire
The Regional mines drainage station at Woolley in West Yorkshire, has discharged at up to 150 litres/sec of minewater containing up to 15 mg/l total iron. This site was the first large engineered wetland system treating mine water in the UK and it was the first treatment site that The Coal Authority commissioned when it was initially set up. The 1.4 ha wetland contains selected plant species known to be effective in mine water flows.
