What is a stormwater attenuation tank?
A stormwater attenuation tank collects and temporarily holds surface water runoff from large storm events. It is most often used for commercial, municipal, and industrial applications.
As urban sprawl continues, permeable ground is being covered with hard surfaces like buildings, roadways, and car parks. This transformation increases surface water runoff and the risk of flooding, especially in areas prone to torrential rains.
Rewatec stormwater attenuation tanks minimize this risk. Made with glass reinforced plastic (GRP) and quality-controlled components, our solutions control the flow of runoff so that stormwater can be safely discharged into a river, lake, or reservoir.
Where are our stormwater attenuation tanks used?
Rewatec stormwater attenuation tanks are most often solutions for:
- underground car parks
- rail yards
- areas prone to flooding
- properties with critical infrastructure
How do our stormwater attenuation tanks work?
A drainage system diverts surface runoff into the stormwater attenuation tank.
The tank temporarily retains runoff in a chamber that controls the volume and velocity of water sent downstream. This controlled release — by way of pumped or gravity discharge — reduces the burden on infrastructure and prevents flooding.
The outlet pipe can direct stormwater to a lake, river, reservoir, or another suitable location, depending on the needs of the site and local environmental regulations.
Stormwater attenuation tank maintenance
Protect your investment in your Rewatec stormwater attenuation tank by having it regularly inspected by a service professional.
When your service provider visits your property, they should:
- check for cracks and leaks in the tank
- clean filters
- update maintenance records for your system
- explain any areas of concern and recommend next steps
