Sweco has been awarded a framework agreement by a Water Board consisting of four water authorities in the southwestern delta region of the Netherlands. The agreement will run from 2026 to 2030, with options for a further two years, and an estimated value of approximately SEK 144 million for Sweco. 

The Water Board consists of the regional water authorities Waterschap Hollandse Delta, Waterschap Brabantse Delta, Hoogheemraadschap van Schieland en de Krimpenerwaard and Hoogheemraadschap van Delfland. They are responsible for flood protection, water levels, water quality and wastewater treatment in the southwestern delta region.

Under the framework agreement, Sweco will collaborate with the four water authorities and provide technical advisory services in hydraulic engineering, flood defence, wastewater and water area management. The services will support the authorities’ efforts to strengthen critical water infrastructure in the southwestern delta region, where climate adaptation, flood risk and water quality are key priorities.

“Sweco has built a longstanding relationship with these water authorities through a series of wastewater and climate adaptation projects, and we are pleased to continue contributing our expertise. As Dutch water authorities face growing environmental and regulatory pressures, we are noting increasing demand for specialist engineering and consultancy services that support infrastructure renewal and long-term resilience,” says Eugene Grüter, Business Area President, Sweco in the Netherlands. 

The total maximum value of the framework agreement for all selected partners is approximately SEK 988 million. Sweco’s estimated share is estimated at approximately SEK 144 million, subject to the award of individual projects under the agreement.

The new agreement reflects the growing focus on climate resilience across Europe. Moreover, it is in line with Sweco’s recent report, Too much, too little, too polluted, which draws on European data and Sweco’s water-sector expertise from several markets.
