WATER ATTENUATION

Water attenuation involves storm water to be temporarily stored for a period of time, normally until the worst of a storm has passed.  The water is then released to the sewer network.

A range of single and connected attenuation tanks form part of a SUDS scheme to provide such attenuation volume.  High volumes of water are controlled during peak or high flows from going through to the mains. Over a period of time this stored water in the attenuation tank exits the system either by gravity or is pumped at a regular rate, thus preventing flooding downstream.

A wide range of tank sizes are available to meet any project requirement. Choice of interior partitions, e.g. with by-pass ducts/weirs, pressure release valves, both load bearing and non load bearing. Choice of access shafts – standard or customised, whether circular, square or rectangular to your height specification.
