Westleigh Pumping Borehole

Tender description

The Coal Authority (client) invites you to tender for the drilling of a mine water monitoring borehole to assess rising mine water on the surrounding environment at Westleigh, Wigan. A review of the mine water block by the Coal Authority has highlighted that mine water levels in the area could be elevated in respect to the rest of the block. There is potential for elevated mine water levels which could pose a risk to the overlying drinking water aquifers. Therefore, the Coal Authority requires construction of a borehole to intersect flooded underground workings at the former Priestner's Colliery at Westleigh, Wigan. The proposed borehole is to be used to improve understanding of mine water in the Golborne, Bickershaw and Parsonage mine water block and will be used for water level monitoring, water quality sampling and abstraction of water. Lot 1: The works required is detailed within the Scope and tenderers are advised to read and consider all aspects of the tender documents before preparing your tender submission. The aim of the documents is to outline the minimum technical and performance levels required by the Coal Authority should your organisation be awarded a contract.
