The existing filter beds were installed in the 1960's and have become inefficient. We plan to remediate the filter beds to construct a mine water treatment scheme. This will require the excavation and processing of current filter bed material, including ex situ stabilisation as a ground engineering technique to provide a geotechnical and geochemically suitable fill. ## CPV classification Technical services Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/2ec12a8f-8a68-4d65-a5e4-45699042c226) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
