Water Harvesting Solutions for Commercial Projects by Wahaso
Commercial buildings can save millions of gallons of potable water each year by harvesting rainwater, greywater, stormwater, and condensate for non-potable applications such as toilet flushing, irrigation, and cooling tower make-up.
Wahaso provides complete design/build water harvesting solutions services, consulting with engineers to determine the best strategy for a project and fabricating a fully integrated system.

Unlocking Retrofit Potential: A Framework for Water Reuse in Existing Buildings
While new construction projects often dominate the conversation around water harvesting, the built environment tells a different story.
Legionella Control in Cooling Towers: Manage Risk and Push Higher Cycles of Concentration
Cooling towers sit at the intersection of building health, energy performance, and water efficiency. They also represent one of the most common environmental sources of Legionella risk. Legionnaires’ disease outbreaks are frequently traced back to poorly maintained towers where warm, stagnant water, nutrients, and biofilms allow bacteria to thrive.
Stormwater Detention Systems and Reuse Opportunities for Commercial Projects
Detention temporarily stores runoff and then releases it at a controlled rate so post-development peak flows approximate pre-development conditions (mitigating flooding/erosion).
