A better standard of living allows increased urbanization, with populations living closely together.
The rapid expansion of water infrastructures, as well as the construction of modern sewage systems, remain important challenges for the future well-being of the world’s population.

Utility tunnelling equipment made by Herrenknecht has been helping to build new, efficient supply and disposal infrastructures in more than 80 countries worldwide.
Around 1,000 Herrenknecht tunnelling machines are in operation around the world, installing water and sewage systems and conduits for power, internet and telephone lines. Building upon this unique expertise and experience, we work closely with our customers and develop tailor-made technical solutions to overcome all challenges and create robust, sustainable tunnel structures – to budget and on schedule, while maximizing safety for the people and the environment.
Road, railway, metro, utility, pipeline, hydropower, mining, and exploration: Herrenknecht’s references include more than 6,200 completed projects around the world. Our tunnelling technology helps to build tunnels, pipelines, shafts, and production wells in all types of ground with diameters ranging from 0.10 to 19 meters. Pioneering technology from Herrenknecht is creating the infrastructure to take people forward, paving the way for progress.
As the world’s leading provider, Herrenknecht stands for:
In short: we make every effort to ensure that your project runs as smoothly as possible, while staying on budget and on schedule.
The availability and sustainable management of water and sanitation for the world’s population was one of the most important development goals defined by the United Nations in 2015. Clear progress has been made since then, but in 2020 there were still billions lacking access to safe drinking water, sanitation and hygiene. So, to reach the goal of 100 % by 2030, current rates of progress will need to be sped up considerably. The rapid expansion of water infrastructures, as well as the construction of modern sewage systems, remain important challenges for the future well-being of the world’s population.
According to the UN Sustainable Development Goals, safely
managed drinking water is located on the premises, available
when needed, and free of faecal and priority
chemical contamination.
The world is changing from mixed sewers and CSO’s (combined sewer outfalls) to separated drainage and sewer systems. This is because during heavy rainfall events, mixed sewers can result in untreated overflows into rivers and other water bodies, which causes pollution and health repercussions to the food chain and humanity. In extreme cases, water bodies may lose all life in them. Therefore, major efforts are undertaken to separate untreated sewage from rainwater into independent systems to send all sewage to a wastewater treatment plant and rainwater to outfalls directly.
In the case of gravity sewers, tunnelling allows for
deeper sewers at lower costs at greater depth.

“Large water treatment plants will
increasingly go underground.”
Construction methods for supply and disposal tunnels must be adapted to the urban topography while observing high safety standards. Herrenknecht tunnelling technology can be installed under extremely tight space constraints. The machines excavate the tunnels and shafts underground following a precise course exactly where they are needed.
The number of sea outfall projects is increasing worldwide. This means that underground pipelines must be driven out from the coastline beneath the sea. The installed pipelines serve as intakes and outfalls for desalination or sewage treatment plants, for example. As part of these projects, tried-and-tested tunnelling technologies and methods by Herrenknecht are used to efficiently and safely drill beneath the seabed, ensuring optimum protection of sensitive ecosystems.
We are ready!
