RELIABLE WATER PIPELINE CONSTRUCTION

MORE SUPPLY SECURITY

Water management worldwide faces the constant challenge of securing the supply of high-quality drinking water and adapting the capacities of the pipeline network to the constantly growing demand. In order to ensure this, while keeping costs for utilities and consumers as low as possible, trenchless technologies offer sustainable and reliable solutions.

PROFITABLE PIPELINE NETWORKS

With our NODIG systems, you can build and maintain your water supply network in a profitable and environmentally friendly way, in existing complex infrastructures as well as in areas where development in open construction is neither ecologically nor economically reasonable. Every requirement can be satisfied reliably, from the installation of pressure pipes for water transport and distribution to the manufacture of house connections to the final consumer and the sustainable renewal of damaged water pipes.

AT A GLANCE

  • Reliable installation of water pipes along roads and under traffic and waterways with short or long pipes made of all standard materials
  • Underground construction of water house connections from the building or directly from the connection room to the main pipe or in the opposite direction
  • Trenchless renewal of irreparably damaged transport pipelines and house connections by the replacement with new pipes in the existing route in order to avoid water losses in the long term
  • Trenchless pipe renewal enables the sustained prevention of leaks while simultaneously adapting the pipe capacity by 1–2 nominal widths
  • Reliable and accurate technology, reliable and proven application
