PRECISE drain installation
using Trenchless technologies

ACCURACTE sewer construction

In Germany alone, the sewerage systems transport more than 20 billion cubic meters of wastewater a year, which is loaded with various pollutants. In order to prevent infiltration of the groundwater,sewer contruction is subject to strict regulations. To ensure absolute tightness and positional accuracy of pressure and gravity pipes to pumping stations, manholes, collectors and buildings, sewer construction requires maximum precision. This precision is guaranteed using innovative trenchless drainage solutions for installing, renovating or renewing sewerage systems. Cleaning of wastewater pipes is also possible.

SUSTAINABLE NODIG drainage solutions

Repair is not a solution for defect sewerage systems with massive damages such as cracks, root ingrowths or socket mis­alignment. However, our NODIG systems for pipe renewal are perfectly suitable for the sustainable renewal of damaged drain pipes and house connections with minimum constructional and financial expenditure, and for the renovation of sewerage systems. Plus you can simultaneously adapt the wastewater pipe capacity by 1 – 2 nominal widths, when replacing old sewer pipes that way.

Trenchless NODIG drainage solutions AT A GLANCE

  • Precise installation of wastewater pressure and gravity pipes along roads and under traffic and waterways, with short or long pipes made of standard materials, also from manhole to manhole
  • Underground drainage construction with gravity pipes for house connections with maximal positional accuracy
  • Trenchless replacement of defective wastewater pipes with round or oval profile as well as house connections with new pipes for sustainable leak prevention 
  • Trenchless canalisation renewal allows for simultaneous adaption of the pipe capacity by 1–2 nominal widths
  • Renovation of wastewater pipes using calibre pipe bursting, relining, pipe reduction or Tight-in-Pipe 
  • Quick and accurate replacement of square and round manhole covers
  • By-the-book and pinpoint drainage solutions, reliable and proven application
  • Precise proof and documentation of position, function and tightness of the new drain
