In addition to the German-based H+E as its headquarters, the engineering and service group makes up a worldwide network across 10 countries, allowing for close proximity to its customers.

The members will also bundle their technology portfolios in plant engineering; the group confirmed more than 30,000 plants have been built with its collective expertise in 130 countries.

"The H+E engineers have been developing reliable and sustainable water treatment and purification plants worldwide for more than 80 years," the umbrella company said, noting that it has enabled production of process water as well as ultrapure water, seawater desalination and wastewater treatment.

"The goal of virtually wastewater-free production is realised with various recycling technologies - known as zero liquid discharge (ZLD) or minimised liquid discharge (MLD) - whereby the company relies on innovative technology that is ‘engineered in Germany'."

The newly restructured compilation of companies said its objective of purifying, protecting and preserving water as humanity's most important resource is deeply rooted in corporate culture.

"This common aim unites the corporate group and motivates our employees," H+E CEO Thomas Will said. "To this day, the company continues to follow the path of founder Willy Hager and live up to his vision: ‘When fresh water first becomes process water and then wastewater, wastewater must also once again become fresh water'."

H+E's technologies include eight key sectors and their respective manufacturing processes: mining; power plants; semiconductor and solar; food and beverage; pulp and paper; chemicals; oil and gas; and pharmaceuticals.
