Attenuation or Infiltration?
Attenuation is the process of water retention on site, slowly releasing it into a controlled discharge to a surface water drain or watercourse. This in effect slows down the release of Stormwater and alleviates flooding downstream. 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, a more bespoke solution such as large bore Twinwall, or Concrete Culverts, Longwater can help. Don’t forget to ask about the permeable or impermeable geo-textile either!
