## About this tender

In partnership with Defra and The Environment Agency, The Coal Authority delivers the 'Water and Abandoned Metal Mines Programme' (WAMM) to help tackle the problem of metal mine pollution and deliver the objectives of the Government's 25 Year Environment Plan and statutory River Basin Management Plans.

The Coal Authority seeks to let an operation & maintenance contract for the Wheal Jane mine water treatment scheme near Truro, Cornwall. The existing operating contract ends in October 2020.

The Wheal Jane mine water treatment scheme treats mine water pumped from below ground using a high density sludge process. The resultant sludge is pumped to a dam and the treated water is discharged to a stream.

In a typical year approximately 6 million cubic metres of mine water is abstracted, 600 tonnes of metal contaminants (predominantly iron and zinc) are removed and 2,000 tonnes of hydrated lime, 7,000 kg of anionic flocculant and 3,000 MW-h of power are consumed.

In addition to the operating plant, the plant infrastructure includes a workshop, storage facilities and office space. The plant is fully manned 8am - 4pm Mon-Fri, with an out-of-hours emergency on-call roster in operation. During peak periods, skeleton weekend coverage is sometimes necessary.

The service required under the contract is the operation of and planned & preventative maintenance to the mine water treatment plant including:

â&#128;¢ Carrying out daily checks on the plant, taking samples and carrying out maintenance activities

â&#128;¢ Making informed adjustments to the treatment process to ensure efficient use of chemicals and power

â&#128;¢ Reporting operational costs, safety statistics and performance trends

â&#128;¢ Provision and management of a database to capture and store plant data

Additional services may be instructed and may include:

â&#128;¢ Project management of capital projects
