Dutch ‘rain fences’ store thousands of litres to shield homes from intensifying storms

AI Summary
Housing providers in the Netherlands are piloting rain‑water storage fences that can hold up to 2,160 litres per garden, easing pressure on overloaded drainage systems during heavy downpours and providing water for drought periods. The initiative, driven by climate‑driven temperature rises and more frequent extreme rainfall, showcases a low‑cost, scalable solution for flood‑prone Dutch neighbourhoods.

In the Dutch town of Veldhoven, social‑housing operator Woonstichting ’thuis has installed the first of its “rain fences” – garden fences that double as rain‑water storage units.

Homeowners Theo and Willy Bolder report that the fence’s linked plastic blocks can retain up to 2,160 litres of water, lowering the load on municipal drains during intense rainstorms and supplying the garden when summer droughts hit.

"The rain is getting heavier and heavier nowadays, and if you have a cloudburst the drainage isn’t good and it comes up through the toilet," Willy explained, highlighting the growing problem of surface runoff in a country where average temperatures have risen by 1 °C since 2000 and cities are about 5 °C warmer than surrounding rural areas (KNMI data).

Recent climate events underscore the urgency: the 2021 Limburg floods saw more than 15 cm of rain fall in 48 hours, causing the River Geul to burst its banks, while the historic 1953 North Sea flood claimed at least 1,800 lives and spurred the iconic Delta Works.

Deputy mayor Rik Thijs of nearby Eindhoven stresses that traditional sewage capacity cannot keep pace with these extremes. "We need to capture as much as possible on the surface," he said, pointing to complementary measures such as resurfacing the old Gender river, creating wadi pools, and installing green roofs.

The rain‑fence concept was developed by Harry den Hartigh of SunnyRain Solutions, whose personal connection to the 1953 disaster in Zeeland inspired a design that merges functionality with aesthetics: a fence that stores water while enhancing the garden’s look.

Academic Jannes Willems, an urban‑planning professor at the University of Amsterdam, notes that simple, scalable solutions like rain‑water harvesting can offset the Netherlands’ “water‑shortage” concerns during hot summers, especially as the national water system was originally built to discharge water as quickly as possible.

For property managers, the benefits extend beyond environmental stewardship. Matthijs Hulsbosch, sustainability manager at Woonstichting ’thuis, says the fences help protect the complex’s 11,000 homes from water‑related damage, potentially saving significant repair costs and reducing tenant inconvenience.

Neighbourhood manager David Hearn adds that the pilot also improves community relations, turning a simple fence into a shared asset that residents are eager to adopt.
