## About this tender

Abandoned Metal Mines cause multiple failures of the Water Framework Directive (WFD) standards in Wales, with c.1,300 mines impacting over 700 km of rivers. 11% of our rivers fail their required quality objectives. In the Western Wales River Basin District mine waters cause 23% of water body failures. Nine of the ten catchments most polluted by abandoned mines in the UK are in Wales.

Cambrian Environmental Technologies (CET) has presented a potential alternative solution for treating neutral pH mine water. The CET Aeroflow SAT (Sustainable Active Treatment) system has been developed based on the need for a flexible and adaptive modular system to account for the complexity and site-specific nature of water treatment requirements in a mining context. This purchase is to undertake lab and pilot trials to enable NRW to determine whether Aeroflow SAT is a suitable, alternative treatment method, which could potentially provide resource, energy and waste saving, generating a cost-effective remediation solution.

Following the completion of Phase 1 (lab trials), this VEAT notice is being published to cover the additional costs for Phase 2 (field trials).
