JN Bentley wins £16M Coal Authority framework

Civil engineering contractor JN Bentley has been awarded a framework contract by the Coal Authority to design and construct water treatment schemes in disused mines.

The Authority, which manages mine legacy issues including subsidence and water pollution, said the four-year deal would be worth between £2.5M and £4M annually. The work involves designing and building new mine water treatment facilities.

The Coal Authority has also awarded a 10-year operation and maintenance contract, worth between £25M and £50M, to Severn Trent Services. The utility contractor will operate and maintain the Authority’s 82 mine water treatment schemes, pumping stations and mine gas facilities in Britain, plus new schemes to be built in the future.

A statement from the Coal Authority said: “The three organisations will be working together using a new partnership approach, which will focus on continuous improvement through the design of innovative and sustainable solutions. Partnership working will take place from concept through to the construction and operation of each mine water treatment scheme.”

The Authority’s existing schemes prevent over 4,000t of iron solids from entering Britain’s watercourses every year. They also protect drinking water aquifers from pollution from rising mine waters. The Authority recently built its first mine water treatment schemes to address pollution from metal mines, at Force Crag in the Lake District and at Saltburn Gill in North Yorkshire.

Simon Reed, chief operating officer for the Coal Authority, said: “The procurement process has been extremely competitive and we received many high quality proposals. We are delighted to announce that we will be combining our expertise with that of Severn Trent Services and JN Bentley to continue to resolve the impacts of mining on the environment. Our programmes for addressing water pollution from both coal and metal mines will be enhanced as we work together to deliver innovation and schemes with strong economic and environmental benefits.”
