WORK on a 60km drinking water pipeline which will secure supplies for residents in the Boston area is on track for completion at the end of the year.

Anglian Water's Covenham to Boston project began in January and work has been going well.

Wendy Kilmurray from Anglian Water's Special Projects team said: "The first 40km of pipe, linking the reservoirs at Covenham and Minningsby, should be completed by the end of the year. More than 24km of pipe is already in the ground, the pumping station at Covenham is also well underway, and at the top of the route we have now begun returning the land to agriculture."

The plan now is to begin preparatory work along the final 20km of the route to Boston before Christmas.

Wendy said: "The wet summer did its best to slow things down but the team have kept to their demanding schedule through hard work and by pioneering new, more efficient ways of doing things."

One innovation has been to produce the pipe in longer lengths; cutting the number of deliveries needed to get it to site and reducing the time spent welding the lengths together.

Another first has been to carry out the dig using a rock trenching machine specially adapted to work in clay, which sped work up considerably. The machine was further adjusted so the soil it dug out was just the right grade to be immediately re-used in backfilling the trench.

Wendy Kilmurray said: "The new ways of working we've trialled have allowed up to 650metre of trench excavation, pipe installation and backfill to be completed in a day.

"Right from the start this project has been a great example of partnership working between us, our contractors and suppliers. There has been a real drive and commitment from everyone involved to save time, money and carbon.

"It also means that, all being well, the first water from Covenham should be coming out of taps in Boston in early 2014."
