Street level gullies feed into Hydrorock infiltration units
BD 340 blocks, standard gullies with sand traps
000m2
Hydrorock natural aquifer blocks have been used to mitigate water pooling and flooding in this large, paved municipal area.
Large areas around the museum have been paved which impedes smooth drainage of rainwater in times of heavy downpour. This results in large puddles creating damage and flooding.
Locally placed Hydrorock street vents channel excess surface water to the connected natural aquifer infiltration blocks via gullies and sand traps, preventing flooding. The street vents are equipped with sand-traps with foliage separators to prevent blockage. Once the water has been absorbed by the Hydrorock blocks, water is gradually released into the surrounding soil.
Sustainable and ecologically responsible
An additional advantage is that, thanks to the Hydrorock buffering zones, the rainwater processing demands on the sewage system is much reduced, allowing it to maintain sufficient drainage capacity. A further advantage is that, because of the infiltration of the rainwater into the soil, the groundwater is replenished in a natural way, which prevents desiccation and keeps the soil in a better condition.
