    Brief

    The Wemyss Metal Mine Works is a remediation project delivered through the Wales Metal Mine Programme (WMMP), a partnership between Natural Resources Wales (NRW) and the Mining Remediation Authority. This project fulfills statutory obligations under the Water Framework Directive and supports the Western Wales River Basin Management Plan (2021-2027). Scheduled for summer 2027, the works include: constructing an upper storage and attenuation pond (approximately 90 metres long, 1.5 metres high) with flow control infrastructure to reduce flows into Upper Mill Race Stream; bypassing a circular collapse feature east of Glanville's Shaft with a new open channel; installing a highway drainage system and filter drain to prevent runoff entering the main spoil tip; and constructing a new lined water channel with flow monitors (approximately 95 metres long) from the public highway to Nant Cwmnewydion, including a new ford crossing and improvements to the existing ford. Suppliers should have expertise in environmental remediation, water management infrastructure, civil engineering for mining sites, and flood attenuation systems.
