Commercial 4" Outlet Vortex Rainwater Filter for Above or Below Grade Application

Figure Number:  RH9518-04
Product Function:
Used in installations where multiple downspouts are connected together to a single pipe into the vortex filter. The vortex rainwater filter can filter up to a 2,200 square foot roof area for site irrigation, toilet and urinal flushing, janitorial use, laundries, fire protection, evaporative cooling tower make-up, process water or other non-potable uses. The vortex fine filter is typically installed in the underground piping system to remove debris from the storm water system and divert 90% of clean rainwater to an underground storage tank. (An above grade application is possible).

Rainwater Harvesting promotes “Green” in the following ways:
  • It lessens demand on the municipal water supply.
  • It makes efficient use of rainwater which would either evaporate or make its way to sewer lines.
  • It diminishes flooding, erosion, and the flow to storm water drains.
  • It reduces the contamination of surface water with sediments, fertilizers and pesticides from rainwater run-off resulting in cleaner lakes, rivers, oceans and other receivers of storm water.
  • It can be used to recharge groundwater.
  • It is good for irrigation and plants thrive because stored rainwater is free from pollutants as well as salts, minerals, and other natural and man-made contaminants.
  • It is good for laundry use as rainwater is soft and lowers the need for detergents.
  • It adds life to equipment dependent on water to operate, as rainwater does not produce corrosion or scale like hard water.
  • Can be used as a potable water supply
  • Ideal for developing  or disaster-impacted areas with limited water
  • It can help achieve LEED® Green Building Credit under Water Use Reduction; Innovative Wastewater Technology; Stormwater Design: quality Control; Stormwater Design: quantity Control; Water Efficiency Landscaping;  and Innovation in Design.
  • Promotes good public relations showing positive environmental concern
