Introducing Intewa, manufacturer of the Purerain hydraulic jump filter. This hydraulic jump technology cleans itself automatically during a heavy storm. The design inspiration comes from nature: you see it in streams. As water flows over large rocks, a swirling eddy forms at the base. The stones are washed clean by the hydraulic force.
During lighter rainfall, the filter is 100% efficient. This is very different from other designs, where the first (only?) rain washes away.
The 4" and 6" sizes are molded plastic, and the larger sizes are fabricated from plastic sheets.
See the chart below for sizes and recommended flow rates:
|SDR 35 Pipe Size||Max. Flow Rate||Rooftop Area (Atlanta)||Above-Ground Model||Inlet Centerline|
to Filter Top
|4"||0 - 90 gpm||1500 s.f.||PR100||3"||1.97"|
|6"||60 - 270 gpm||5000 s.f.||PR150S||4.1"||HD150||5.9"|
|8"||270 - 576 gpm||10,000 s.f.||PR200||5.4"||HD200||6.1"|
|12"||577 - 1684 gpm||30,000 s.f.||PR300||8.75"||HD300||10.7"|
|16"||1685 - 3630 gpm||70,000 s.f.||PR400||10.2"||HD400||13.62"|
* The "Invert" in the chart above is the drop from inlet to outlet. These are some of the lowest in the industry, and allow for filters to be installed inside tanks, out of sight.
The below ground models are suitable for direct burial, and have an access opening for filter cleaning.
There are more expensive downspout filters, but our experience is that this one is the best. . .
THE NEXT GENERATION IN RAIN HEADS
The Leaf Eater Advanced™ is the next generation Rain Head, featuring the new Clean Shield™ (single screen) technology and VH Pivot™ outlet. The Leaf Eater Advanced™ Rain Head prevents debris from entering the Rain Harvesting system, improves water quality and reduces tank/cistern maintenance.
The single screen incorporates Clean Shield™ technology which deflects leaves and debris away from the flow of water. This minimises maintenance and enhances catchment efficiency. This Rain Head incorporates a VH Pivot™ outlet that swivels to suit vertical or horizontal downspouts. The Leaf Eater Advanced™ can also be used as a debris removing device even when rainwater is not being collected.

Residential Water Quality Device
AN IN-GROUND FILTERING SYSTEM, SCREENING LEAVES AND DEBRIS OUT OF YOUR PIPES
Filter Pits handle large volumes of rainwater and enable screening to be done at a central point in the system. In some cases they can be safer and easier to clean than rain heads fitted at roof gutters.
Filter Pits are extremely beneficial when used in conjunction with underground tanks/cisterns or where tanks/cisterns are placed downhill from the building. They are usually placed at a convenient spot in the garden, between the tank and the house. Filter Pits are a ‘junction’ where the various pipes from around the house meet from which the main pipe or pipes then connect to the rainwater tank/cisterns.
