Waterketen

Waterketen is a Dutch concept describing the integrated chain of activities, institutions and infrastructure responsible for the management of water from source to user and beyond. It encompasses the production and distribution of drinking water, the collection and treatment of wastewater, drainage and flood protection, and the management of surface and groundwater ecosystems. The aim is to ensure safe, reliable and affordable water services while protecting public health, the environment and climate resilience.

The waterketen comprises several interlinked components. The drinking water supply chain includes intake, treatment, pumping and distribution. The wastewater system covers sewer networks, transport to treatment plants, and the discharge or reuse of treated water. Drainage and flood-protection systems manage stormwater and river basins to prevent flooding. In addition, surface water and groundwater management safeguards water quality and ecological status, supporting sustainable use of water resources. Key actors include drinking water companies, regional water boards (waterschappen) responsible for water safety and flood risk, municipalities and provinces for planning and local implementation, and the private sector for construction and operation. National authorities set overarching policy and EU directives guide standards.

Governance in the waterketen relies on integrated planning and coordination across sectors through long-term programs, shared data and risk-based investment decisions. This approach seeks to optimize cost efficiency, resilience to climate change, and environmental protection. Challenges include aging infrastructure, leakage, funding and coordination across many organizations and jurisdictions, and balancing reliability with long-term investments.
