Welcome to Water Harvesting Solutions!

Commercial buildings can save millions of gallons of potable water each year by harvesting rainwater, grey water, condensate and other on-site sources for non-potable uses like toilet flushing, irrigation and cooling tower make-up. Wahaso provides complete design/build systems custom-tailored to each building.

Rainwater harvesting is the most common system type, and Wahaso specializes in commercial rainwater harvesting systems. Unlike the more simple systems installed for homeowners, our rainwater harvesting systems are designed with the commercial-grade components and sophisticated controls required in commercial buildings for reliability, automated functions and connectivity to BAS systems.

In geographies where rainwater is less abundant, greywater (gray water) can be an excellent source for harvesting. Greywater harvesting systems collect water from showers and sinks and other
“gentle” uses that can be safely and effectively treated for many non-potable uses.

In residential buildings, greywater systems can be less expensive than rainwater harvesting systems because daily supply and demand are in synch, eliminating the need for large storage tanks. Wahaso’s greywater processing system design has been field-tested and proven to be compliant with the tough NSF-350 water quality standards for commercial greywater harvesting systems.

Many of our systems are multi-source and multi-use which can help to maximize water savings and optimize a system’s ROI. One system might collect rainwater, cooling condensate and groundwater to flush toilets and irrigate landscaping. Is rainwater harvesting, greywater harvesting, stormwater harvesting or a combination of these best for your project? Contact us and let us Scope your project. Our process begins with Scoping, where we quantify potential sources and uses of non-potable water and recommend a system design and budget. There is no charge for our evaluation and recommendations.
