Storm/Rainwater Attenuation

Storm/Rainwater Attenuation

An attenuation system works when the peak inflow rate in a storm exceeds the allowed discharge into the watercourse. The excess flow has to be 'attenuated' by storing the water on the site for the duration of the storm. This is then released at, or less than, the allowed discharge rate after the storm.
