Rainstream Water Storage & Re-use System

Rainwater management system offering a range of highly-effective solutions for the filtration, storage, attenuation and re-use of rainwater in commercial applications and public buildings.

Up to 80% of the water Commercial and Public buildings consume is used for non-potable applications such as toilet flushing, irrigation and evaporative cooling. Much of this could be provided by harvested rainwater.


Polypipe Rainstream is a bespoke, fully engineered rainwater harvesting system based on the same proven technology as the Ridgistorm-XL large diameter pipe range. It’s a tank of exceptional stiffness and integrity that can be transported quickly and efficiently. It can be installed without the need for a concrete surround or the need to fill the tank with mains water to weigh it down during installation.
