Engineering Framework for Water Infrastructure and Flood Defense Systems

Sweco and a consortium of four Dutch water authorities have established a multi-year framework agreement to engineer and optimize regional hydraulic infrastructure. The collaboration focuses on deploying technical advisory services for wastewater management, flood defense systems, and water quality control in the southwestern delta region.

Collaborative Infrastructure Development
The partnership involves Sweco and a Water Board comprising Waterschap Hollandse Delta, Waterschap Brabantse Delta, Hoogheemraadschap van Schieland en de Krimpenerwaard, and Hoogheemraadschap van Delfland. The authorities are responsible for managing water levels, flood protection, and wastewater treatment systems. The complexity of environmental regulations and physical climate factors necessitates specialized engineering cooperation to upgrade existing infrastructure and ensure long-term resilience.

Applications and Use Cases
The target application areas encompass hydraulic engineering, flood risk mitigation, and municipal wastewater processing. Technical use cases involve the structural assessment of flood defenses, the design of climate-adapted water retention systems, and the optimization of wastewater treatment parameters to meet strict environmental compliance requirements. These engineering interventions are designed to maintain process stability, operational safety, and resource efficiency across the regional water networks.

Technical Solution and Responsibilities
Within this framework, Sweco functions as the technical advisor for engineering design and system evaluation, while the water authorities manage the physical infrastructure and operational deployment. The joint effort relies on implementing resilient infrastructure models that integrate climate adaptation data into infrastructure renewal planning. This division of responsibilities ensures that all upgraded facilities adhere to updated European water quality and safety standards.

Implementation Phases and Deployment
The framework covers an implementation period from 2026 to 2030, with a potential extension of two additional years. Engineering frameworks and advisory processes will be integrated directly into the authorities' existing infrastructure planning cycles. Sweco will support the engineering and design phases as individual projects are awarded, ensuring that structural modifications are phased in systematically without disrupting current water management and treatment operations.

Expected Impact and Operational Scale
The collaboration will reinforce the southwestern delta's water infrastructure against physical and regulatory pressures through measurable improvements in flood risk reduction and processing efficiency. The framework agreement has a total maximum value of approximately SEK 988 million for all selected partners, with Sweco's allocated share estimated at approximately SEK 144 million based on the future award of individual projects.

Eugene Grüter, Business Area President at Sweco in the Netherlands, stated: "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."
