SUDS - Polystorm


Polystorm is designed to provide a range of modular build tank attenuation systems specifically for loaded applications.

Each Polystorm unit is light enough to carry which gives excellent health and safety and installation benefits.

Installations can be built up to form a load bearing tank structure capable of accomodating the majority of site constraints to receive rainwater collected from roofs or car park areas.

Polystorm integrates with other solutions in the Stormwater Management range including Ridgidrain, Stormcheck flow control chamber, silt traps and gullies to provide a range of attenuation solutions to suit many applications on or off plot.
