Scheme cleaning up mine water with help of old tyres
THE quality of water in 4km of a Bridgend river will be improved as a mine water treatment scheme is now up and running.
Installed by the Coal Authority in the valley of the Nant Craig Yr Aber near Cefn Cribwr, the scheme is cleaning up the water flowing from old coal mine workings in the area.
The Coal Authority said the high iron content of the mine water had been staining the Nant Craig Yr Aber a bright orange colour.
Work on the £1.8m scheme began in 2014.
The project comprises a water cascade, two settlement ponds and reed beds, together with pipework, access tracks and footpaths found at similar Coal Authority schemes.
However, it also hides a unique feature – the use of a “waste” product – recycled tyres – as a construction material for the first time.
The Coal Authority said around 1,000 old tyre bales were used as engineering infill within the core of the embankment work.
