How Do Attenuation Tanks Work

Stormwater attenuation tanks are ideal if you’re looking for a bespoke and cost-effective solution to control the flow of water back to a watercourse or drainage system. They are commonly used for larger commercial applications.

What is an Attenuation Tank?

Stormwater attenuation tanks provide a storage system for rainwater & surface water. The stored water inside the attenuation tank is released via a flow-control chamber and is either pumped via a pumping chamber or run-off through a gravity stormwater pipe system.

Why use an Attenuation Tank?

This is an alternative to soakaway crates or an elevator.  Where the previous two methods of storm attenuation simply catch water from their surrounding area, a separate tank has the ability to capture water from a very wide area using connected pipes and collect it all together in one huge tank for distribution.

They are generally preferred on larger commercial applications because they can be quicker to install than other stormwater attenuation systems.

How do Attenuation Tanks work?

Attenuation tanks work by collecting the excess rainwater and having a flow-control chamber, this controls the amount of water being pumped out into the drainage system. This reduces the risk of flooding and allows a choice of distribution, and then the pipes can carry the water to various areas – dependent on your needs.
