Rainwater Harvesting Products

  High capacity strainer filter that requires 7″ of vertical drop to function.
 Single filter will clean water from 2,000 SF (186m2) of roof catchment area to 250 microns.
 Water must be pre-cleaned before the filters.
 Easy clean mesh screens last 5 years.
 Can be installed outdoors if mounted horizontally.

Maintenance – Clean every 1-2 months. If filters are not cleaned water backs up in catchment piping.

  Milk filter fabric fashioned into a coffee filter shaped liner for a standard tank top basket.
 Operates with dirty water, but pre-cleaning of larger debris recommended.
 Zero water loss at flow rates of 10GPM which equates to 1/2″ rain per hour from 2,500SF (232m2) of roof area.
 Requires 6″ (150mm) vertical drop at tank top.
 Filters water to 40 microns.

Maintenance – Clean basket and filter every 2 months if water is pre-cleaned. Every month if water is not pre-cleaned. Filters can be cleaned 2-4 times and then replaced.

  Basket style gravity flow rainwater filter for mounting underground. No water loss if operating properly.
 Requires 10″ (255mm) vertical drop.
 Filters water to 350 microns.
 Rated to process water flows from roof areas up to 3,770 SF (350m2) when fed by a 4″(100mm) pipe.
 Equipped with its own overflow, if the basket cannot process peak water flows or becomes clogged with debris.

Maintenance – Clean out basket every 2-3 months if water is pre-cleaned. Every month if water is not pre-cleaned. Note: Other models of Graf filters clean water to similar standards with less vertical drop requirements.

  Vortex style filter for installation above or below ground. Clean water flows out the sides of the stainless steel cylinder, and excess water and debris drop down into the drain exit.
 Minimum 10% water loss increases dramatically if vertical vortex surface collects debris or gets dirty.
 Requires 10.2″ (260mm) vertical drop.
 Filters water to 500 microns.
 WFF 100 rated for roof areas up to 2,153 SF (200m2). WFF 150 rated for roof areas up to 5,380 SF (500m2)
 Designed to be self-cleaning but water should be free of fir needles.

Maintenance – Remove and clean internal Stainless Steel cylinder every 1-2 months to prevent filter from rejecting more than 10% of water flow. Note: smaller “downspout” WISY filters are rated for 1,614 SF (150m2), and a larger one is rated for roof areas to 32,000 SF (3,000m2)

  Basket style gravity flow rainwater filter for mounting above grade or partly underground. No water loss if operating properly.
 Requires 10″ (255mm) vertical drop.
 Filters water to either 200 or 750 microns (depending on filter basket used).
 Combines basket filter with small pump chamber to transport water to storage tank(s).
 Rated to process water flows up to 80GPM when fed by a 4″(100mm) pipe. Roof area serviced depends on pumping capacity.
 Equipped with its own overflow, if the basket cannot process peak water flows or becomes clogged with debris.

Maintenance – Clean out basket every 2-3 months if water is pre-cleaned. Every month if water is not pre-cleaned. Add chlorine to trapped water every 1-2 months. Clean pump chamber every 6 months.

  A small version of a commercial water cleaning box used in pulp mills and wineries.
 Water flows over a concave shaped piece of stainless steel “Wedgewire” material that draws clean water through it.
 Virtually self-cleaning as debris and excess water flow over wedgewire and out a drain.
 Operates with dirty water. No pre-cleaning required.
 Zero water loss at flow rates of 20GPM (92LPM) which equates to 1/2″ rain per hour from 5,000SF (1,525m2) of roof area.
 Installs above ground or partly underground. Requires 17″ (430mm) vertical drop.
 Filters water to 500 microns.

Maintenance – Brush wedgewire surface with SS brush every 2-3 months. Remove and pressure wash wedgewire panel every 1-2 years.

  The ultimate gutter cover.
 A robust aluminum frame covered with a 316 SS screen mesh that cleans the water to 200 microns before it gets to the gutter.
 Sits on angle to help it self-clean.
 Eliminates requirement for debris traps. Almost eliminates gutter maintenance.

Maintenance – If water flows over the top of accumulated debris brush with a brush head on an extender pole. In spring after pollen season brush or pressure wash top surface to dislodge pollen build up. In extreme environments it may be necessary to remove and pressure wash both sides every 2-3 years.

  Locally made, lightweight aluminum frame covered with 40/40 surgical stainless steel mesh that cleans the water to 380 microns on the way into the gutter.
 Sits flat on gutter hangers.
 Removes most debris including roof granules.

Maintenance – Water can still run over the top of built up debris requiring periodic brushing of top surface. Most pollen runs through it witch simplifies spring cleaning.

  Similar to the All-in-one debris box, but equipped with a stainless steel cover to deflect larger debris.
 Cover reduces roof area capacities by approx. 20%. Some splashing (water loss) can occur in heavy rains.

Maintenance – Clean every 2-4 months.

  Attractive, 8 inch semi circular design constructed of heavy gauge coated aluminum.
 2 stage cleaning like the All-in-one debris box.
 Mounts on two screws on the wall for easy removal.
 For roof areas up to 1,400 SF (130m2)

Maintenance – Clean every 1-2 months.

  Made by Rain Harvesting Pty Ltd.
 Angled leaf screen designed to partially self-clean.
 No secondary water cleaning.
 For roof areas up to 1,200 SF (112m2).
 Minor splashing and water loss in heavy rains.

Maintenance – Clean every 1-2 months

  Inexpensive 2 piece system that diverts larger debris in top leaf trap, and collects finer material in the blue fabric & grate under it.
 Minimum 10% water loss increases dramatically if vertical vortex surface collects debris or gets dirty.
 No secondary cleaning.
 For roof areas up to 700 SF (65m2)

Maintenance – Clean every month – more often in areas with many fir needles.

  Inexpensive screen basket that mounts in the downspout. Removable for cleaning.
 No secondary cleaning, but traps fir needles.
 For roof areas up to 700 SF (65m2)

Maintenance – Clean every month, and as often as weekly if gutters are uncovered in wooded areas.
