How It Works

How it Works

A basic ReWater® filter package consists of a surge tank that can stand alone or be buried, a bolt-on lid that can be sealed and walked on, water-proof grommets, wastewater backflow valve, heavy-duty high pressure submersible pump, float switch, and bag filter.

Our more advanced filter packages also have an outdoor-rated fiberglass sand filter system that can be fully automated, with a fresh water valve to backwash the filter vessel, a pressure-reduced valve to provide supplemental irrigation when needed, and a reduced pressure principle device to protect the fresh water supply from a reverse flow of greywater.

Larger automated filter systems for multi-family and commercial buildings are also available.  All our filter systems deliver filtered greywater to our proprietary subsurface drip irrigation network.

Filter and irrigation operations can be controlled by ReWater’s Complete Control™ controller, which comes with every ReWater irrigation package.  Our controller starts when water is available, sends water out to irrigation as programmed, and stops when the tank empties, holding its place in the program until more water becomes available.  This process keeps the water fresh and full of oxygen, which is good for the filter, irrigation infrastructure, and plants.

Our outdoor rated 6, 9, 12, 15, 18, and 21-station controllers have 156 features, including 4 independently operating programs, to make sophisticated irrigation easy yet highly efficient under real-world conditions.  Our 33 and 45 station models have a heavy steel cabinet for more demanding neighborhoods.  All our controllers have the ability to automatically supplement, after midnight, any shortage of recycled water with fresh water.

Our irrigation packages come with practically all the valves, tubing, emitters, and hundreds of little fittings you need for a landscape approximately the size you’re planning, and you can customize each package.  Each component has been tested over time to deliver an optimal irrigation experience over the long haul.

ReWater’s systems have been chosen by discriminating homeowners for over two decades because our components and methods for their assembly have been carefully selected and evolved from our extensive experience.  We guarantee our systems will give you many years of trustworthy service.

The most economic way to install a ReWater system is by plumbing only the regularly-used showers, tubs, and clothes washer into our surge tank: about 95% of the reusable water comes from these few sources.  Bathroom sinks produce another 3%, and guest showers, tubs, and bathroom sinks contribute the remaining small portion.
