RELIABLE WATER PIPping networks

More security of supply with trenchless water main installation

The water industry worldwide faces the constant challenge of securing the supply of high-quality drinking water and adapting the capacities of the pipework system to increasingly growing customer demand. In order to ensure this, while keeping costs for utilities and consumers as low as possible, trenchless technologies offer sustainable and reliable solutions. By installing water conduits and water service connections without trenches, the costs of adapting the water piping network are kept as low as possible for suppliers and consumers, the environment is protected and the supply is secured in the long term.

PROFITABLE WATER PIPING NETWORKS

Using Nodig technology for water main installation, you can build and maintain your 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. Various methods can be applied, from the installation of pressure pipes for water transport and distribution, to the fitting of a house connection and the sustainable renewal of damaged water pipeworks.

Water conduit construction with Nodig technology at a glance

  • Reliable water main installation and water pipeline construction along roads as well as under traffic and waterways with short or long pipes made of all standard materials
  • Underground water conduit construction for service connections from the building or directly from the connection room to the main pipe or in the opposite direction
  • Trenchless renewal of irreparably damaged pipework w new pipes in the existing pipe path for avoiding water loss in the long term
  • Trenchless renewal of water conduits enables the sustained prevention of leaks while simultaneously adapting the pipe capacity by 1–2 nominal widths
  • Reliable and accurate technology for water main installation, secure and proven application
