Raintaina Filter Chamber
The best way to protect an underground drainage system from blockage is to install measures at source which prevent silts and
other detritus from entering an underground network.
Raintaina RWP Filter Chambers provide pre-treatment to downpipe run-off, presenting an effective barrier to harmful elements flowing from roofs.
Rainwater discharges on to the top of the chamber such that any silts, leaves, windfall, etc... is retained on top of the filter cover. The cover is easily removed for cleaning.
