What is an attenuation tank?
An attenuation tank collects and stores surface water run-off from large storm events or heavy rainfall. They are usually used for larger municipal or commercial applications.
The stored water inside the attenuation tank is released at a controlled rate to slow down the level of excess run-off before being released into a local water course such as a river, lake or reservoir. This minimises the risk of localised flooding - an increasing issue in the UK where sporadic torrential rain events are becoming more and more common.
Example applications
- areas under threat of stormwater
- areas prone to surface water flooding
- municipal
- commercial
- industrial
- protection of infrastructure from floodwater
- railways
- underground car parks
How does a stormwater attenuation tank work?
Attenuation tanks work by collecting excess rainwater and retaining the overflow until it can be safely discharged into the environment.
By incorporating a flow-control chamber within the tank, the amount and velocity of rainwater / stormwater being pumped out into the drainage system can be controlled, thus greatly reducing the risk of flooding to the local area.
Pipes can then carry the water to various locations depending upon the needs of the site and local planning authorities.
Attenuation tank maintenance
Protect your investment in your Rewatec attenuation tank by having it regularly inspected by a qualified service professional.
When your service provider visits your property to inspect your system, they should:
- check for cracks and leaks in the tank
- clean filters
- keep and update maintenance records for your system
- explain any areas of concern and recommend next steps
