bubbling water
Water is our mission.

For more than 30 years, we have been investing our knowledge and experience to give back to water what it is increasingly in danger of losing: its purity.

Weil Wasser­aufbereitung GmbH

. . . develops, plans and manufactures customized plants for the production of drinking water, pure water and ultrapure water as well as for the treatment of industrial wastewater.



We are a globally active, medium-sized company based in Osnabrück, Germany. There we have a laboratory, an assembly hall, stainless steel processing, an electrical workshop, and small-scale production-in short, everything we need to make our enthusiasm for the purest water known far beyond the borders of the country.

When it comes to high demands on water quality or special water treatment problems, we are your contact people. Dedicated employees advise on problems related to water quality and find individual solutions.

Plant construction and planning services as well as product and process development around the topic of water are "our thing". Whether it's plant construction, planning services, process and product development or aquarium [and] household products, our team of engineers, technicians, and fitters is at your disposal with innovative and customized solutions. We have had extensive experience and first-class references since 1986.
