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.

Rainwater System

The practice of harvesting rainwater dates back centuries and is still the most common type of water harvesting system. Wahaso specializes in designing and building rainwater harvesting systems for large-scale applications. Unlike the simple systems installed by other rainwater harvesting companies for homeowners, our rooftop 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. The Wahaso commercial rainwater harvesting systems produce treated water that is safe and suitable for non-potable applications such as toilet flushing, irrigation and cooling tower make-up

Greywater System

Greywater (also referred to as graywater, grey water, and gray water) is “gently used” water captured from showers, lavatory sinks, laundry, and light commercial processes. It can often be an excellent source of water, saving thousands or even millions of gallons of water per year. Given the contaminants inherent in greywater, it is important that any grey water systems are designed properly. Wahaso’s grey water recycling systems for commercial properties has been certified to meet both IAPMO 324 and NSF/ANSI 350 standards. The Wahaso greywater harvesting system has been tested and proven to provide a safe, treated supply of water that can be used for a variety of non-potable applications.

Condensate System

Commercial buildings with forced-air cooling systems have the potential to generate condensate, a steady source of water that can be harvested for reuse. In air handling units (AHUs), as air passes over the cooling coils, moisture in the air condenses and drips into a pan below the AHU. In many cases, that water is sent to the sewer system, wasting a valuable source that can be treated and used for non-potable applications. A Condensate Water Recovery System can turn that wasted source into a usable source. Wahaso’s condensate system is compact, pre-assembled and designed for
easy installation.
