Wahaso’s Greywater (Gray Water) Systems
Wahaso’s patent-pending greywater harvesting system is explained in detail. This is the system currently in NSF-350 certification for safety and effectiveness in processing gray water. Download Wahaso’s Greywater System Info Sheet.
Wahaso Control Systems
All functions of a rainwater or greywater harvesting system must be monitored and managed by a smart central controller. Learn more about how Wahaso designs and builds custom control systems that also record and graphically report system activity. Download Wahaso Controls Information Sheet.
Wahaso Pressurization Skids
Critical to any rainwater or gray water harvesting system is the pressurization system that will provide the correct amount of GPM and PSI to deliver harvested water to the point of use. Wahaso designs and builds custom pressurization skids that come pre-tested with complete controls, warranty and on-site commissioning. Download information sheet on Wahaso’s Pressurization Skids.
Wahaso’s Atlantis Tank System
Wahaso recommends the Atlantis D-Raintank system for rainwater harvesting systems. The system is infinitely scalable and flexible, uses recycled polypropylene and passively protects water quality in the tank. And it is less expensive than fiberglass or concrete storage systems. Download Info on the Atlantis System.
CorGal Steel Tanks from Wahaso
For above-ground storage of harvested rainwater or stormwater, CorGal tanks offer unlimited options and sizes in attractive, long-lasting corrugated steel. Download information on CorGal tanks from Wahaso.

RESOURCE LINKS FOR HOMEOWNERS
Water Harvesting Solutions only provides services for commercial and institutional buildings. Homeowners interested in harvesting rainwater or greywater are encouraged to review the following links:
Residential Rainwater Harvesting
The American Rainwater Catchment Systems Association is the official rainwater harvesting association. Their website offers resources for homeowners and has lists of suppliers for small systems. http://www.arcsa.org/
The two most popular books on rainwater harvesting are from Brad Lancaster. Rainwater Harvesting for Drylands and Beyond, Volumes 1 & 2, show you how to turn water scarcity into water abundance by creating an integrated, multifunctional water-harvesting plan specific to your site. Volume one covers Guiding Principles and Volume 2 focuses on Water-Harvesting Earthworks. Visit Rainwater Harvesting for Drylands and Beyond.
Georgia also recently published guidelines for rainwater harvesting. Georgia Rainwater Harvesting Guide.
Residential Greywater Harvesting
Greywater (gray water) Reuse: Recent legislation in California has changed building codes so that homeowners can capture greywater from washing machines and apply it directly to subsurface irrigation without treatment. Simple systems can be built by homeowners and installed without permits. This is a great starting point to begin to shift the reuse of water in California. If you wish to use shower and sink water for irrigation, you will need a permit. Please check your local municipality for restrictions and guidelines in your are.
For more information on subsurface irrigation, you can download an instructional document from Greywater Action or visit Greywater Action.Org. Oasis Design, http://www.oasisdesign.net, offers a wide range of books and references on greywater, rainwater and other sustainable practices.
