ACO facts and figures – expansion with a clear focus

As a family enterprise under the direction of Hans-Julius Ahlmann and his son Iver Ahlmann, ACO can develop and implement long term strategies without bending to external pressure. Our success proves us right. Thanks to internationalisation and diversification we can balance out large fluctuations in local construction sector markets, and stabilise our expansion course.
The ACO Group is a world market leader in drainage technology. Climate change sets us a challenge to react effectively with innovative solutions to new environmental conditions. With its integrated approach, ACO stands for professional drainage, efficient cleaning, and the controlled discharge or reuse of water. Products include drainage channels and drains, oil and grease separators, backflow stop systems, pumps and pressure-water-tight cellar windows and light shafts.
The family-owned company headquartered in Rendsburg/Büdelsdorf, Germany, was founded in 1946 on the site of the Carlshütte foundry – Schleswig-Holstein’s first industrial company. It still has very strong roots in the region. The innovation strength of the ACO Group is built on intense research and development, and its technical expertise in processing polymer concrete, plastic, cast iron, stainless steel and reinforced concrete.
