Uniwater grows in Denmark – enters into agreement to acquire Danish WASYS and ACOWA

Uniwater continues its growth journey and enters into an agreement to acquire Danish WASYS and ACOWA, specialists in electricity and automation for water and sewage. The acquisitions increase Uniwater's presence in Denmark and strengthen the group's expertise and offering in automation solutions for water infrastructure.

Wasys and Acowa are two sister companies based in Roskilde, Denmark. The companies offer complete solutions, products and services, for control and monitoring of the water cycle in society. The companies have special expertise in pumping stations and their base of installed pump controls and instrumentation constitutes a loyal and returning customer base. The customer base is typically within public sector, but also in industry, real estate and the construction sector. Following the acquisitions, Wasys and Acowa will be integrated into Uniwater’s business area Flow.

– The acquisition of Wasys and Acowa is an important step for Uniwater. We strengthen our position as specialists in water infrastructure and gain access to unique expertise in automation and metering in the Danish market. Together with Wasys, Acowa and our other companies, we see great opportunities for product development and synergies,” says Martin Evertsson, Director of Business Area Flow at Uniwater.

Wasys and Acowa were founded in 2014 and are led by CEO Christian Poulsen

– We look forward to becoming part of Uniwater and together further developing solutions for the water infrastructure of the future. Through the collaboration, we gain access to new contacts and skills, and can offer our customers an even broader and stronger offering, says Christian Poulsen, CEO of Wasys and Acowa.

The transaction is expected to close in the fourth quarter of 2025 following customary regulatory approvals.
