Rainwater Interception, Storage & Control

Roof and Podium Rainwater Interception, storage and control for Commercial and Public Buildings
Traditionally, rainwater has been collected within a below ground storage tank and released into the sewer in a controlled fashion. In recent years this has become more difficult because of the space limitations within urban environments.


To get around this problem Polypipe has developed our Rainwater Interception System which intercepts the rainwater at source at roof and podium level of commercial and public buildings using geocellular storage cells and controls the water flow, using our Terrain variable flow outlet and trusted terrain drainage pipe systems, to the underground drain.

For further information, please see our Rainwater Interception System and Rainwater Interception Outlet product pages.
