Water supply and water resilience

Protection against flooding and accessibility to clean water

With our Dutch roots, we know how to fight against and for water. Global challenges persist in ensuring access to safe drinking water, sanitation, climate-resilient infrastructure, and water management. Cooperation, innovation, and investment are vital to address these societal challenges effectively.


In the Netherlands, we contribute to the High Water Protection Program by designing, constructing, and maintaining flood defenses and dikes. With expertise in hydraulic engineering and innovative technologies, we strengthen the Netherlands against flood risks, making communities safer and enhancing the country's resilience to high water.

With a history in water management, like working on the Afsluitdijk from 1927 to 1932 and the Oosterscheldedam between 1976 and 1986, we gained a good reputation for working with water. This is still relevant when working on today’s projects. Further away from home, in Sri Lanka, we provided 17,000 families in seven villages with clean drinking water. Ballast Nedam was responsible for arranging financing, the management during the entire project and the knowledge and expertise.


In the area of Hemmathagama (Sri Lanka) the river Auphinella rises on top of a mountain. Currently, the inhabitants of seven villages in the area still drink untreated water. The construction of an intake and water treatment, connected to a newly laid out pipeline network, will change that. Clean drinking water means fewer diseases and less pressure on healthcare.

Ballast Nedam handled the project from design up. It includes the connection to 17,000 houses, as well as the placement of water meters. Good community engagement management was essential since the 17,000 houses were spread over seven villages.

Managing water

The Netherlands is a low-lying country with a significant portion of its population and economic activity concentrated in coastal areas. Rising sea levels pose a threat to these areas and require measures such as dike reinforcements and coastal protection. Extreme rainfall and rising sea levels increase the risk of flooding in the Netherlands, particularly in river deltas and low-lying areas such as parts of the provinces of South Holland and North Brabant. More extreme rainfall can lead to waterlogging and flooding, as well as longer periods of drought, affecting agriculture and water supply – resulting in an estimated 3.4 billion people living in water-stressed areas by 2030. If we want to protect ourselves from water and protect water from pollution, collaboration between government agencies, water boards, private sector entities, and research institutions is crucial for addressing water challenges and implementing sustainable solutions in the Netherlands and beyond.

Rijnkade Arnhem

Commissioned by the Rijn and IJssel Water Board and the municipality of Arnhem, we are ensuring that the Rijnkade reinforcement will last for another 100 years and the city will be protected from high water. Nearly all the construction equipment we use on site is electric. Next to that, we supply almost all concrete work by water from our water hub. From our land hub, we make sure to always leave with a full truck. Working from these hubs saves a lot of transport movements.
