Infiltration systems are an efficient solution for absorbing storm water directly at its place of origin. Storm water cassettes are suitable for large sites, and storm water tunnels for smaller sites.
Uponor storm water cassettes are ready-to-install modules. The cassette system can be inspected and maintained using an inspection cassette installed on the lowest level. Storm water cassettes can be installed as layers of ten and at depths of up to 5 metres.
Cassettes coated with welded PE-film can be used to delay storm water. If required, Weholite tanks can be used as retention tanks–these are tailor-made for each site and can be equipped with voiding pumps if required.
Storm water infiltration is typically used in commercial centres, car parks and traffic areas, terminals, and depots. The structure of the cassettes enables flexible installation in accordance with the available space. There are several options for connecting the cassettes to storm water pipes, and they are always designed specifically for each project. The material is polypropylene (PP).
The Uponor storm water tunnel is suitable for storing and infiltrating storm water on small sites, such as single-family homes. The material is polypropylene (PP). Connection sizes are 110–315. Also see our drainage solutions.
