Wemyss Scour Protection

Tender description

The Site is located approximately 2km north-west of New Row, on the road to Abermagwr. The grid reference for the centre of the site is SN SN716 741. The spoil tips of the Wemyss mine site lie to the north and south of the Cwmnewydion Road. The Lower Mill Stream is culverted under the road and flows south to its confluence with the Nant Cwmnewydion. The Lower Mill Stream is eroding the tips on the south side of the road, particularly where it exits the culvert under the road and hits the side of the tip with high velocity. Between October 2024 and January 2025, a section of tip approximately 1m high, 0.5m deep and 4m wide collapsed into the stream. The works are required to reduce the erosion of the tips. The works comprise laying rock rolls at the toe of the tips in the places where they have been observed to be actively eroding, in accordance with the Mining Remediation Authority drawings Lot 1: The Site is located approximately 2km north-west of New Row, on the road to Abermagwr.
