Scheme clean­ing up mine wa­ter with help of old tyres

Glamorgan Gazette - - News -

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.
