Commercial buildings can save millions of gallons of potable water each year through harvesting rainwater, grey water, cooling condensate and other on-site sources for non-potable uses such as toilet flushing, irrigation, cooling tower make-up, and vehicle wash. We provides complete design/build systems custom-tailored to buildings and sites. While providing free design and system sizing at a project’s front end, Wahaso ensures their systems are fully customized to accomodate the particular suppy and demand variability in place.
The primary driver for water harvesting is typically not ROI. The LEED rating system, local stormwater code and the value of green marketing can all present important incentives for building owners to pursue water harvesting and reuse. That said, depending on the project, ROI may be as low as 1 year. A variety of variables influence this, including local water costs, size of cistern storage and amount of annual rainfall, graywater, etc.
Water harvesting provides a holistic approach to reusing water that would normally travel to the sewer. By harvesting rainwater, stormwater, cooling condensate and other sources, the amount of water annually used in a building can be dramatically reduced. In fact, in some building types, over 90% of the water for flushing toilets, irrigation and cooling tower make-up, could come from a non-potable source.
