sab approved rainwater downpipe treatment filter unit

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.

Raintaina RWP Filter Cover
RTNA06001

The Raintaina RWP Filter Cover Gold is the first stage of filtration of the Raintaina system. The various range in colours and styles of aggregate makes the cover blend in with the surrounding surface making this system almost invisible. The cover will stop any leaves or unwanted objects entering the system. The indents on the side of the cover make it quick and easy to install and maintain the Raintaina Base unit. If preferred there is an alternative filter cover available which retains a loose gravel to match the gravel margin around a house.
