New Polypipe concept with built-in Biomaster antimicrobial protection

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 popular Ridgistorm-XL large diameter pipes. The Rainmaster range comes with built-in Biomaster Protection, a safe, effective and permanent antimicrobial additive based on silver ion technology. 

With Biomaster Protection the range has been independently tested to ISO 22196:2011 and has been 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 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. Exceptionally strong, Rainstream RXL offers all 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. And with no need to fill the tanks with water during installation, tens of thousands of litres of water can be saved. 

“Rainstream RXL has been designed and developed to help specifiers, engineers and contractors overcome these challenges and achieve significant cost and environmental savings too,” said Darren Crane, National Sales Manager Rainwater Harvesting at Polypipe.
