Works for complete or part construction and civil engineering work

Tender description

The works are the construction of a mine water treatment scheme at Nent Haggs. The works include: • the provision of a site compound for the duration of the works and the reinstatement of the site compound site following completion of the works; • the construction of a capture structure to capture the raw mine water at source (the capture point); • the design of a rising main to transfer the mine water from the pumping station to the treatment site (the transfer route); • the construction of gravity pipework and rising mains to transfer the raw mine water from the capture point to site 4 (the treatment site); • the construction of a pumping station on site 38 (the pumping station site); • the earthworks to form the finished levels at the treatment site; • the construction of a hydrogen peroxide dosing system at the treatment site; • the construction of flow control and distribution pipework at the treatment site; • the construction of the outfalls for the treated mine water to the River.
