Pump hire specialist, Sykes Pumps, has provided the pumps and pipework required to enable drainage improvements to be carried out at a problematic area of track between the villages of Peak Dale and Doves Holes in the Peak District.

QTS Group carried out the project on behalf of Network Rail following the build-up of calcium carbonate deposits on existing drainage channels. These deposits, caused by heavy lime content in the soil and high concentrations of soluble calcium hydroxide in the water table, were impeding the passage of water, thereby increasing the flood risk.

The scheme involved installation of new track drainage, including three new under track crossings (UTX), alongside a sidings renewal project. In order to carry out the work safely, an over pumping operation was required to maintain a safe working area throughout the project.

The Sykes Pumps team worked with the engineers from QTS to calculate the flow rate requirements for the scheme and specified a combination of Super Wispaset 100mm and Super Wispaset 150mm silenced pumps, along with bunded fuel tanks and 800 metres of pipework. The company delivered all equipment to site and worked with QTS and Network Rail including the local maintainers and freight companies to carry out full installation and commissioning to ensure that the water was pumped safely away from the work area at all times.

The pumps remained operational 24/7 throughout the project, with Sykes Pumps managing regular pump maintenance as an integral part of the hire contract.

Comments Wes Crompton, project manager at QTS Group: "We replaced the existing 250mm diameter track drainage pipe between Sidings No.1 and No.2, along with a section of 350mm diameter track drainage pipe between Siding No.1 and the Down Goods line, using pre-cast reinforced open concrete carrier units with GRP mesh grid covers.

"This location is renowned for flooding and has caused problems over the last ten to twelve years for Network Rail and the private freight operating companies who lease the sidings. All parties including the stake holder managers and the sponsor have been very keen to find a solution that's feasible in line with the RAM (Route Asset Managers) proposals and budget for works in this area. The project was successful in meeting the requirements of all parties and offers a simple yet integral service route with a sustainable maintenance schedule that's cost affective.

"The work will divert run off from the track bed and carry it through to the existing open ditch outfall, creating a solution that will be much easier to maintain. We couldn't have completed the work without the effective over pumping solution designed, installed, commissioned and maintained by Sykes Pumps."
