Telemetry equipment

Tender description

The Coal Authority (TCA) wishes to appoint a contractor to provide a replacement telemetry system for the Mine Water Treatment Schemes (MWTS) it owns and manages. These schemes remove contaminants, such as iron, from water that flows through old mine workings, before discharging the treated water back into the watercourse. Being able to monitor the health and performance of the equipment at these schemes is therefore vital in ensuring the effective running of the schemes and in helping TCA to meet the discharge consents set by the Environment Agency. The telemetry replacement project will cover 47 Mine Water Treatment Schemes (MWTS) located over 49 separate sites. These sites are located on the Coalfields in Scotland, the North East, the North West, Yorkshire, the Midlands and Wales, with a total of 39 sites in England, 5 sites in Wales, and 5 sites in Scotland. Some of these sites are covered by an existing telemetry system, which will be replaced by the new system.
