Polypipe unveils new rainwater harvesting system

26 Jun 12 Polypipe is responding to the growing need for sustainable rainwater re-use systems with the launch of its Rainstream RXL.

Rainstream RXL high volume water storage tanks are available with an optional anti-bacterial lining and have been engineered using the same technology as Polypipe’s Ridgistorm-XL large diameter pipes.

The Rainstream RXL tank’s modular design allows any storage capacity to be created and features an integral pre-storage filter - eliminating the need to make connections between the chamber and the tank. 

Rainstream RXL offers the functionality of large-scale GRP sub surface tanking and in most cases can be installed using a single sized granular backfill, as opposed to a more costly concrete support structure.

“Although high volume below ground tanks offer enormous flexibility in the planning and provision of water storage for large scale projects, they present big challenges in transport and installation,” said Darren Crane, national sales manager rainwater harvesting at Polypipe.

“Rainstream RXL has been designed and developed to help specifiers, engineers and contractors overcome these challenges and achieve significant cost and environmental savings too. The fact we are able to manufacture the tank to any stiffness classification allows for a broad range of installations, be it below the water table or in heavily trafficked areas.”

The modular construction of the Rainstream RXL allows for easier on-site handling, off-loading and positioning. Assembly is straight forward with Polypipe’s Electro-Fusion jointing technology.

Rainstream RXL also comes with optional Biomaster protection within its polymer lining.  Biomaster is a silver based anti-microbial additive that Polypipe says is proven to reduce the growth of harmful, pathogenic bacteria such as Legionella, Listeria, Campylobacter, MRSA, E.coli and Pseudomonas on the inner surface of the tank by up to 99.9%. The Biomaster-protected parts of the Rainstream RXL have been tested to ISO 22196:2011 standards.
