Save money and enjoy peace of mind

Our self-cleaning greywater sand filter, easy to use proprietary controller, and underground drip irrigation system conserves water and saves you money!

Rain or shine, drought or not, the average 3.2 person single-family home produces about 46,000 gallons of greywater every year, and our system uses that water at least 30% more efficiently in precise underground drip (up to 60% in hot, windy climes).

Reuse the water you’ve already paid for and keep your landscape green and blooming all year. Plants love it!

And enjoy long, guilt-free showers knowing this good water isn’t becoming a downstream problem.

Evolution at your fingertips

Now with our 5th generation of controllers, the ReWater system has all the unique features you want and need to automatically reuse your water in any type of landscape you design. It can even control sprinklers using city water on a separate program!

Time-proven reliability

The ReWater® System has been in use at single-family homes for nearly four decades. It’s the original Showers-to-Flowers™ system and it’s the only greywater system proven by a long track record.

But what about NSF-350 systems?

“NSF-350 Certified” doesn’t mean it works in the real world.

The greywater irrigation industry is littered with now defunct companies that had the “latest and greatest” NSF-350 certified greywater irrigation system that didn’t work long outside the lab.

Plumbing officials know NSF-350 certified systems fail due to normal laundry processes like heavy lint days, chlorine bleach surges, and detergent surfactant overloads. That’s why they contractually force you to pay a factory technician to go maintain NSF-350 certified systems at least annually and re-certify that they’re still working.

The new April 2026 State of California regulations are even more draconian. They completely remove NSF-350 as an approved standard for legal compliance and require systems to undergo far more stringent initial testing, continual testing, and annual re-certification by a professional, which the system owner must pay or risk fines. And these state regulations are even retroactive!
