Some of the plastic filters can be seen discarded by the side.
But the maintenance problems associated with the tanks and media becoming clogged were not initially appreciated and it no longer operates, with the beck still being stained by mine water.
I seem to think that the same problem at Skelton Beck in Saltburn may have now been solved?
Skelton Beck is using settling ponds as far as I can see.
