Trenchless pipe rehabilitation of an egg-shape combined sewer

IMPREG Liner optimally suited

Our IMPREGLiner is known worldwide and is popular among application engineers for its flexibility and optimal handling, At this jobsite, our GRP pipe liner GL 16 was ideally suited for the egg profile 700/1050 WD 7.4 mm.

The rehabilitation area between the spillway and manhole was divided into a section consisting of a Brick wall and a section constructed of concrete pipes. The three sections with lengths of 65 m, 37 m and 136 m had an old pipe in condition II. Due to the location of the rehabilitation area (the Prussian side runs parallel to Leipzig Central Train Station), the urgency was top priority, and the choice of trenchless sewer rehabilitation was a perfect solution for this construction project.

Excellent result

“The well experienced installing team and the great cooperation of all parties involved were the success factors,” says Christian Pfaff, Sales DACH at IMPREG GmbH. The client, Kommunale Wasserwerke Leipzig GmbH, can now boast a successful reconstruction. The rehabilitated combined sewer now looks like new and is equipped for a long and durable future.
