About our brand

Our Passavant® brand has a long tradition in sewage technology.

The production of the first canal castings in the in-house foundry started an exciting chapter for Passavant. It continued to advance the development of sewage and drainage technology. Our focus is concentrated on the manufacture of reliable, innovative and high quality materials.

Many machines and process technology were already used for the first time in the 19th century by the Passavant Werke AG and revolutionized the sewage treatment. Concentrated on the production of machines and technologies for the treatment of water and the treatment of municipal and industrial wastewater. Since 1994, the company is certified by the quality assurance system DIN ISO 9001.

By visiting trade fairs and exhibitions, the contact with the customers becomes established, maintained and deepened. That is the reason why we participated at the international trade fair for water, sewage, waste and recycling materials (IFAT) in Munich, since 1969.
