The Benefits of Buried Infiltration Tanks
Buried infiltration tanks avoid saturation of the sewer networks
Buried Infiltration tanks can be located below roads, parking lots, service stations, logistic platforms or other landscaped areas. In urban and suburban areas, the land value is very high and thus opting for a buried system is a real advantage for owners.
Buried infiltration tanks aim at storing temporarily the runoff water below the ground. Runoff water arrives through inlets and pipes connected to the other stormwater conveyances. If there are heavy rainfalls, the overflow goes to an adjacent drainage system like the municipal storm sewer. Municipalities may face the saturation of the networks, building buried infiltration tanks is one of the best stormwater management practice.
A buried infiltration tank eases the process of infiltrating water locally.
Buried infiltration tank acts as buffer and decrease the flood risk, discharge water slowly into the ground depending on the soil permeability while allowing municipalities, developers to use the land above as site amenity or to increase biodiversity, creating thus, a better environment for the citizens.
However, in urban and suburban areas, runoff water is polluted with hydrocarbons from vehicles oil leaks on car parks, in urban streets, on logistic areas, construction site driveways, courtyards or communal spaces. Polluted water shall be treated before reaching the aquifers.
Designing infiltration tanks with the TenCate GeoClean® aquatextile is a means of ensuring systematic treatment of hydrocarbons in all configurations.
The added value of aquatextiles
Why use our TenCate GeoClean® aquatextile in buried Infiltration tanks?
- High oil retention capacity over the whole infiltration surface covered by the aquatextile, bottom and sides
- Direct infiltration of oil depolluted water
- Economical water treatment solution
- Ease of installation
Installing TenCate GeoClean® aquatextile
Installing TenCate GeoClean® aquatextile in the buried infiltration tank is a time and cost-efficient solution to secure the water depollution
Case study
Buried infiltration tank made with crates below townhall place
France, Bruay-sur-l’Escaut (59)
Two buried attenuation and infiltration tanks were built in front of and behind the town hall.
Buried infiltration tanks are one of the best stormwater management practices for the following applications:
