Mining remediation authority update

The Mining Remediation Authority are carrying out works at Dalkeith building a mine water treatment works to treat waste water from former mine workings. Once complete the works will remove metals and other contaminants from the Esk  
During these works a problem was discovered with the Old Fordell tunnel which carries water from mine workings to the Esk. This has resulted in a temporary pipeline being installed to deal with the backed up water. The Mining Remediation Authority are working with Midlothian Council to install a permanent solution.
There is information on the mine water treatment works here, Dalkeith | Coal Programme. Updates on the temporary mine water pumping and plaaned permanent solution are available here, 19 June 2026 : Mining Remediation Authority .
