PRECISE SEWER CONSTRUCTION

GUARANTEED ACCURACY

In Germany alone, the sewer networks transport more than 20 billion cubic meters of wastewater a year, which is contaminated with a wide variety of pollutants. In order to prevent infiltration of the groundwater, the construction of wastewater pipes is subject to strict regulations. To ensure that the pressure pipes and gravitation lines to pumping stations, manholes, collectors and buildings are absolutely tight and accurate, sewer construction requires installation of the highest precision. This precision is guaranteed in trenchless pipeline construction, if the pipes are being installed or renewed. Pipe cleaning is also possible.

SUSTAINABLE SAFETY

Repair is not a solution for massive pipe damage such as cracks, root ingrowths or socket mis­alignment. However our NODIG systems for pipe renewal are perfectly suitable for the sustainable renewal of damaged sewer pipes and house connections with minimum constructional and financial expenditure, and for the renovation of sewer systems.

AT A GLANCE

  • Precise installation of sewage pressure pipes as well as gravity lines along roads and under traffic and waterways, with short or long pipes made of standard materials, also from manhole to manhole
  • Precise underground installation of gravity lines for sewer house connections from or to manholes or pits
  • Trenchless replacement of non repairable pipes, for house connections by replacing them with new pipes for the sustained prevention of leaks while simultaneously adapting the pipe capacity by 1–2 nominal widths
  • Quick and accurate replacement of square and round manhole covers
  • By-the-book and pinpoint techniques, reliable and proven application
  • Precise proof and documentation of position, function and tightness of the new pipelines
