Ridgistorm attenuation solutions feature a tank structure manufactured from large diameter Ridgidrain pipes with welded end plates. Ridgistorm attenuation tanks receive rainwater from roofs, roads or car parks and store water ready to release within a set discharge limit. Tanks are available in a range of diameters up to 6.0 metres in length as standard, however, the length may be increased by joining multiple units together on site.

Largest range of BBA certified pipes and fittings allowing developers to obtain NHBC insurance Tanks of any size fabricated from stock Ridgidrain diameters and lengths Accessible via a secure access cover for inspection and cleaning Lightweight for ease of handling and installation combined with high stiffness and durability

Properly designed Ridgistorm attenuation systems, incorporating suitable catchpits, require no maintenance other than the removal of silt and leaves from the catchpit. On plot attenuation systems are generally privately owned and are not adoptable.

Ridgistorm units are installed in the same tried and tested way as conventional flexible pipe systems. Ridgistorm units are suitable for intallation under car parks or roads. Separators are required only in high risk areas with sustainable drainage systems. Consult Polypipe Civils for further advice.
