MUNICH: Sweco has signed an agreement to acquire STEIN Ingenieure GmbH, an engineering consultancy with about 60 experts across several locations in Germany, the company announced. The deal will expand Sweco’s presence in the water sector and position it to capture more business in a growing segment.
STEIN Ingenieure specializes in sewer rehabilitation, wastewater and drinking water infrastructure, structural engineering, pipe jacking and inspections of engineering structures. The company’s experts will join the more than 1,800 professionals already working for Sweco Germany as soon as possible.
“I am excited to welcome the experts from STEIN Ingenieure to Sweco,” said Julia Zantke, Business Area President for Sweco in Germany. “Germany’s water sector is entering a period of major transition, with modernisation, climate resilience, ageing infrastructure and stricter EU requirements driving urgent action. Together with our new colleagues from STEIN Ingenieure, Sweco will continue to support German water utilities, municipalities and other clients with the delivery of secure, efficient and future-proof water and wastewater solutions.”
STEIN Ingenieure reported turnover of approximately 6.5 million euros in 2025. Sweco’s Business Area of Germany & Central Europe reported turnover of approximately 271 million euros for the same year.
“The acquisition of STEIN Ingenieure marks a clear next step for Sweco in Germany,” Zantke said. “Going forward, we will focus on expansion in selected areas. This includes the water market, where needed modernisation is driving good demand.”
Germany is one of Europe’s largest and most advanced water and wastewater markets, where climate pressures, aging infrastructure and increasingly strict regulations are fueling demand for investment and innovation. Severe flooding in western Germany in 2021, along with recurring drought and low-water periods since 2018, has underscored the need for greater resilience in the sector. National and regional priorities continue to drive investment in water security, network upgrades and more efficient wastewater solutions, according to Sweco.
Sweco’s water management experts work with public and private clients on issues ranging from access to clean water to flood protection, offering services in water and wastewater engineering, water resource planning, urban water management and the design of flood protection structures.
The acquisition is part of Sweco’s broader growth strategy, which combines acquisitions with organic growth to expand the skills and reach of its roughly 23,000 experts across Europe. The company describes itself as Europe’s leading architecture and engineering consultancy. Sweco has completed close to 170 acquisitions over the past 20 years, including 13 in 2025 alone, which added approximately 2.1 billion Swedish kronor in annual net sales and more than 1,500 experts to the company.
