Utility Tunnelling

Efficient supply systems built underground

________________ As the world's population grows, the need for underground supply tunnels is also increasing; this is just as true for threshold and developing countries as for modern urban centers. For this reason, around 850 Herrenknecht Utility Tunnelling machines are in operation around the world constructing and installing water and sewage systems, gas and oil pipelines, conduits for power, Internet and telephone lines as well as headrace tunnels for hydropower plants.

Trenchless tunnelling offers a range of advantages compared to conventional construction methods: transport, economy and environment remain largely undisturbed while Micromachines, HDD rigs or shaft sinking equipment are being used.
