SINCE 1972

Wastewater technology made in Germany. HAMANN AG is a worldwide recognized manufacturer of sewage treatment technology for the maritime industry. Since being founded in 1972, we serve our clients helping them to meet ever stricter regulation on sewage discharge and thus to rise to our joint responsibility to protect the marine environment.

Our commitment to quality goes far beyond the R&D, engineering and manufacturing processes. The same amount of effort and attention to detail goes into every step that follows; from sales to engineering consultancy to commissioning and technical support many years later. We document that in our ISO 9001 accredited quality management system as well.

We offer a high level of customization and extensive consulting services to ensure the best possible solution for every project.

From there on, we make sure with excellent technical service that our clients have all the backup they need to operate their HAMANN plant during its entire lifespan. We do so with our highly qualified and experienced staff at HAMANN headquarters near Hamburg, Germany and with our global network of over 40 sales agents and service partners.

All that accounts for the fact that HAMANN plants ensure continuous high effluent quality, reliability in day-to-day operation and low maintenance to the benefit of our clients and the oceans.

HAMANN AG is a privately held company with founder Knud Hamann acting as Chairman of the Supervisory Board. All HAMANN sewage treatment plants are designed and manufactured at our facility in Hollenstedt, Germany.
