Attenuation Storage Tanks
Any structure that creates a below ground void that may be used to temporarily provide surface water storage prior to infiltration, whether reused or discharged in a controlled manner, are generally termed as attenuation storage tanks. They have significantly higher storage volume capacity than granular-filled structures and can be used beneath areas with a primary purpose other than drainage, including amenity, roads and parking areas.
