Home Products Technical About Us


  • photosThe home metal roof does not shed itself, only the stuff that comes with the rain events, the wind debris, and the birds. So the roof can not flavor the rain water.

  • The gutters have screens that prevent the large debris, such as leaves and bones (birds) from going any farther.

  • At the bottom of each downspout is a debris diverter. This is a collection pipe that allows the first flush (of which is typically the most contaminated) to enter into a semi-closed pipe. This pipe fills till the rainwater overflows to an alternate path that goes to the cistern.

  • At the cistern, the incoming stormwater goes into the smaller squared holding tanks. These tanks are called stratifiers. The rainwater enters into these stilling basins – allowing whatever that can sink to sink and whatever that can float to float. Only the middle portion of the water column which is the cleanest can continue into the main 5,000 gallon holding tank.

  • The holding tank has a graveled maintenance area around it. It is under the main house floor with the floor joists all painted with a bio-inhibitor. This dark space has passive vents to allow for open air circulation.

  • The pump intake is located away from the 3 stratifiers and mounted about 2” off of the floor.

  • The Repressurization Pump is a self priming end suction sump pump with on/off pressure controls.

  • The rainwater is pumped through a 5 micron filter prior to supplying the home toilets, the laundry areas, and the hose bibs with water.

  • A float switch is located of the bottom of the main 5,000-gallon holding tank. The float switch closes when this tank is empty. The signal will switch off the recirculation pump and open up a second pressure sensor circuit that will allow city water pressure to supply the toilets, laundries, and hose bibs until adequate rain has started to fill the tank back up.

  • When the 5,000 gallon holding tank is about to overflow, the collected rainwater in the stratifiers will overflow into a standing pipe along with all of the floating debris (typically organic) and down to an outside french drain.
