Water Management


Attenuation or Infiltration? Attenuation is the process of water retention on site and slowly releasing it in a controlled discharge to a surface water drain or watercourse. This in effect slows down the release of Stormwater into the watercourse and alleviates flooding lower down the system. Infiltration or soak-away is the temporary storage of water to allow it to naturally soak away into the ground.

So if you need “Attenuation Crates” from stock, or a more bespoke solution such as large bore twinwall, or concrete culverts Longwater can help.
