Wahaso Services in California


Wahaso – Water Harvesting Solutions has designed, built, and installed hundreds of water collection and reuse systems across the United States and Canada, including many in California amid the current drought. Wahaso evaluates each individual project and environmental factors in order to provide the optimal solution for each building, resulting in more sustainable and environmentally sound water use.

The result of our efforts is lower costs for municipal water use, less impact on community stormwater and sewer systems, and a more sustainable source of water for toilet flushing, irrigation, and other uses. We work closely with architects and engineers in the process of designing buildings to provide the scoping, engineering support, and manufacturing of turn-key systems. Our clients feel better about how their buildings impact the environment, and that they are part of the solution for a greener, more sustainable world.

Wahaso is a leader in supplying custom water harvesting systems for commercial properties in California, where recently-passed regulations require new building projects to include stormwater management. These regulations are outlined on the following pages:

Water Harvesting Systems from Wahaso

With 25+ years experience in water harvesting system design and implementation, we are experts in systems for large buildings. It is our core competencies in system design, filtration, control systems, our experience, and our focus on only the commercial and institutional building market that set us apart from other rainwater or greywater system suppliers.

Wahaso is an approved vendor in the state of California that can combine stormwater management and greywater reuse into an integrated commercial water harvesting system. Wahaso’s systems comply with the NSF/ANSI Standard 350 and all local codes, including all new regulations. As members of the U.S. Green Building Council (USGBC), we understand the broader goals and concerns of clients interested in achieving LEED certification for their building, and we can actively support the design and documentation of a water harvesting approach to maximize LEED points in this area.
