Product Information
In Situ Attenuation Tanks
In situ tanks are ideal for retention, attenuation or infiltration applications when used with a suitable geomembrane or geotextile. Their modular nature allows flexibility of shape - ideal for shallow excavation systems, narrow strips or use in restricted areas. They can be used as part of a SuDS system. The system is suitable beneath asphaltic, block-paved or concrete pavements and for the full range of traffic conditions from domestic driveways to highways.
Prefabricated Tanks
Prefabricated attenuation tanks provide an ideal solution for sites with limited space or smaller developments with lower stormwater storage requirements. The tanks are available in sizes up to 6.5m long x 2.5m wide x 1.2m high which provides 18.5m³ of storage. Smaller tanks can be provided to specific site requirements. All tanks
are provided with integral pipe connection spigots in a range of diameters that suit standard UPVc push-fit drainage.
Prefabricated Liners
Prefabricated attenuation tank encapsulation often referred to as ‘Shoe Box’ liners are ideal for smaller attenuation tanks allowing self installation. Guidance can be provided on the installation. The liners can be manufactured in a variety of membrane types such as PP or LLDPE and sized to suit your project specific requirements. Pipe connections can be also be supplied, and are available in a range of diameters.
