What We Do

What We Do

We help owners in new construction save a fortune in water and wastewater costs by reusing the building’s shower, tub, and laundry water in our time-proven, sophisticated yet easy-to-use ReWater® irrigation system.

Each ReWater system consists of a site-specific filter package and our proprietary underground drip irrigation system package.  Our highly evolved systems are found at estate homes, apartment buildings, barracks, and other residences supporting beautiful landscapes. Their owners earn money from water reuse, efficient irrigation, run-off pollution prevention, and wastewater reduction. Return on investment can be as fast as 2-3 years for multi-family systems and profits then add up to tens of thousands of dollars over the life of the system. LEED and Build It Green points are also available.

We’re not offering mysterious black boxes or expensive water purification units that negate savings, as found on other websites. Rather, we help architects, engineers, plumbers, and landscape professionals in new construction with our cost effective, complete multi-family filter packages, backed up by potable water, some of which are also backed up by rain, which all use our proprietary controllers and underground drip irrigation to keep working for decades.

No matter what size system your project’s landscape requires, every ReWater system works on our tried and true principle of using water as it’s produced, keeping it full of oxygen and good for plants, all according to your project’s irrigation needs. No landscape is too complex for our controllers.

Our systems satisfy the US EPA and Bureau of Reclamation’s 20-year life requirement for SRF and other funding, as well as state and local funding criteria.

If you’re building a new multi-family or other high occupancy residence that needs irrigation, or lots of them, please email or call us at (805) 716-0104.


Separate the showers and laundry water from the rest of the wastewater sources, attach our filter system, reuse the water in our highly efficient drip irrigation system, and save a fortune.

All legal sources of greywater/graywater are showers, tubs, bathroom sinks, laundry water, HVAC condensate, and RO discharge. 97% comes from showers and laundry. Once that water is separated indoors, it’s typically brought outdoors, where a surge tank sized for the anticipated peak surge is attached with an overflow back to the sewer.

That tank is vented and captures the water just long enough for the pump, sized per the topography and other factors, to pressurize and send the water through the sand filter and out to the ReWater irrigation network according to irrigation programs on our controller.

Our whole process is backed up with potable water, should the landscape need more water, like when most students go home for summer break, or Marines or soldiers get deployed, or midweek at destination resorts, etc. However, most high occupancy projects have more than enough water for their landscapes year-round.

Data shows the average 3.2-person home produces 46,000 gallons of reusable water, year after year. An average 320-occupant hotel at 100% occupancy produces about 4,600,000 gallons each year. That much water can support a massive, lush landscape.

With that in mind, you must know how much water your landscape actually needs before we can design the correct system.  If a 320-occupant building’s landscape could reuse all its water, over a 30-year period it would reuse 138,000,000 gallons or over 423 acre-feet of water, worth over $650,000 at current retail rates and over $1,500,000 when considering water price increases.

Then there are wastewater savings on top of that. Most sewage treatment districts charge about the same as fresh water, so double your return on investment from metered savings.  The present value of a ReWater system at a high occupancy building with a large irrigated landscape always greatly exceeds the installation and maintenance costs of the system.
