When the $4.3 billion California aqueduct was finished in 1963, few thought it would be overdrafted by 1990, but it was. Since then, over 4.5 million housing units have been built.

ReWater® started up across and down the street from the birthplace of Silicon Valley on Addison Avenue in Palo Alto in 1990 to help California meet its water needs through robust, cost-effective, environmentally helpful “greywater” recycling irrigation systems.

ReWater worked tirelessly with California’s then bipartisan legislature, building and environmental health officials, builders, architects, engineers, contractors, and landscapers to create a code that would result in greywater irrigation systems that meet everyone’s needs for beautiful, sustainable landscapes.

In 1996 ReWater, moved to San Diego to help that thirsty city satisfy its one-of-a-kind federal water reuse mandate.

In 2000, using US EPA’s long-established State Revolving Fund (SRF) criteria for funding water systems, California’s State Water Resources Control Board’s SRF Branch determined that the ReWater system qualifies for US EPA SRF loans. The SRF program requires a system to last 20 years.

In 2009, we moved up to Thousand Oaks to better serve all southern California.

ReWater’s systems evolved to integrate rain and other types of water in 2010.

We don’t offer cheap internet systems that break down or clog, or expensive wastewater disposal systems that leave you needing a real irrigation system. If you want the real deal, you’re at the right place.

Early on, we crunched the number and determined that if every new residence in California used a ReWater system over the next 30 years, collectively those systems would provide, drought or not, the equivalent of any one of the multi-billion dollar water projects that bring water to southern California, but at a fraction of the cost and with less environmental downsides.
