Frequently Asked Questions

What is an attenuation tank?

Attenuation controls the flow of water as it goes back to the water course or drainage system, which is valuable if tackling flooding downstream or an overwhelmed infrastructure. Attenuation consists of the temporary storage of surface water in a suitable chamber below ground level.
