Our ENVision Vision

For the last five years JN Bentley has been proud to work with The Coal Authority on minewater remediation projects under its ENVision I Framework.

Following our success throughout this framework, we are now delighted to report that in December 2009 The Coal Authority announced that our bidding for the ENVision II Framework had been successful, securing work with the client for the next four years.

We were also extremely pleased that the first framework finished on a high last year when The Coal Authority’s Dawdon project, which we were involved in, scooped the “Water & Wastewater Project” Award at Edie’s third annual Awards for Environmental Excellence.

The award was clinched for the innovative approach to protecting the water table of Durham from contamination.  The mass closure of collieries in the area during the early 1980s meant that the pumping of minewater from the underground workings had stopped. 

This had caused a threat of minewater contaminating the overlying aquifer (which provides 36 million litres of drinking water a day) as well as minewater discharges onto the East Durham coast line and River Wear.

In the most complicated minewater treatment scheme ever to be constructed in the UK, the project was successfully carried out for The Coal Authority in an excellent demonstration of the benefits of collaboration, involving all of their engineering and environmental partners including JN Bentley, WS Atkins, Interserve and Mott MacDonald.

The Dawdon project was also commended in 2009 by the Institution of Civil Engineers in the over £4m category of the prestigious Robert Stephenson Awards and we had also won The Coal Authority’s own Environmental Performance Award for our part in this project during 2008, which made it the second year in a row that we had won this award.
