The long dig is ended

An 80t tunnel boring machine used to construct a major trunk sewer for Leicester has reached the end of its drive after more than a year underground. The œ15 million Abbey Sewer project, commissioned by Severn Trent Water, was designed by Haswell Consulting Engineers and constructed by Balfour Beatty Civil Engineering. The TBM drove 6km of tunnel, negotiating crossings of the River Soar, the Grand Union Canal, a large man-made lake and a landfill site.
