Climate changes cause increasing flooding issues in the Dutch cities. Prolonged or brief and intense downpours increasingly cause the streets to become flooded as the drainage capacity is insufficient for this excess of water. This also applies to the situation around the Amsterdam Rijksmuseum which has been housed in the Rijksmuseum building since 1885. The Municipality of Amsterdam has chosen the smart Hydrorock solution and has placed the Hydrorock infiltration system at multiple locations around the Museum. Local solution against flooding also relieves the sewerage system Around the museum large areas have been metalled which forms an impediment for smooth drainage of rainwater in times of heavy downpours. The result: large puddles which create damage and flooding. Via locally placed Hydrorock street vents the connected infiltration blocks are fed with excess water and thus flooding is prevented. Subsequently the infiltration blocks partially release the rainwater into the soil. The street vents are equipped with a sand-trap with foliage separator to prevent blockage. Sustainable and ecologically responsible An additional advantage is that, thanks to the Hydrorock buffering zones, the sewerage system needs to process less rainwater and thus it maintains sufficient drainage capacity. Another advantage is that because of the infiltration of the rainwater in the soil, the groundwater is replenished in a natural way, which prevents desiccation and keeps the soil in a better condition.
