WATER MANAGEMENT SOLUTIONS

BURIED ATTENUATION TANK

Water pollution solution for buried attenuation tanks

Buried attenuation tanks are alternative stormwater management solutions in urban and suburban dense areas while offering a maintenance-free system to discharge clean hydrocarbon depolluted water directly to the environment thanks to the TenCate GeoClean® aquatextile.

The Benefits of a Buried Attenuation Tank

Buried attenuation tank, interconnected system to reduce floods

Looking at the current economic and environmental climate, stormwater management and flood control are in many people’s minds. Surface water shall be controlled, knowing that the sewer systems are often overloaded. Collection systems can cause floods, pollution and may not be sustainable on a long term, thus damaging our environment. Additionally, dense urbanization and intensive rainfalls led the municipalities to plan and invest in buried systems.

In urban and suburban areas, water is polluted with hydrocarbons due to oil leaks from vehicles on car parks, in urban streets, on logistic areas or construction sites. Polluted water shall be treated before reaching the aquifers.

Storing and slowly releasing is one of the benefits of the buried attenuation tank, rather than letting water go quickly into sewers or watercourses.

Buried attenuation tank acts as buffer and decrease the flood risk while allowing municipalities, developers to use the land above as site amenity or to increase biodiversity, thus creating, a better environment for the citizens.

Runoff water that is stored in the buried attenuation tank is polluted with hydrocarbons from car parks, gardens, landscaped areas, driveways, courtyards or communal spaces. The percolation of this polluted water through the TenCate GeoClean® aquatextile laid at the bottom and at the sides of the attenuation basin into a drainage layer makes possible a direct discharge of clean water to the environment.
