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.

Design Build Services

For Architects

When a building is being designed, we scope the harvesting system by thinking through the best sources and uses for on-site treated water. We recommend the size and type of system and provide a rough estimate of the project's cost.

For Engineers

We team up to provide the detailed system designs, drawings and specifications.

For Installing Contractors

We serve as the manufacturer of the specified system. We pre-assemble and test all components at our facility and then ship them on skids ready to be installed as an integrated system by the local contractor.

For Property Owners

We provide training and support for operating and maintaining the installed system and warrant the entire system for a year.
