Grey Water Harvesting Systems
Wahaso Grey Water Harvesting Systems
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.
Greywater is gently used water from sinks and showers. It may also include washing machine water. Greywater contains fewer contaminants than domestic wastewater, making it safer to handle and easier to treat and use in irrigation, toilet flushing, cooling tower make-up and other non-potable applications. Once greywater is properly treated and processed with a greywater harvesting system it is called on-site treated non-potable water.
Grey Water Recycling Systems Design
IAPMO 324 and NSF/ANSI 350 Certified
GW-UF35-50, GW-UF70-100, GW-UF140-150 and GW-UF210-210 are certified by IAPMO R&T against NSF/ANSI 350 and IAPMO IGC 324.
- Fully Automatic Processing. Raw grey water is treated as it is generated to minimize the growth of harmful pathogens.
- Low Maintenance. The system has been designed to run reliably for long intervals, with minimal maintenance required.
- Scalable. The Wahaso greywater system can be scaled to treat from 2,000 to 200,000 gallons per day or more.
- Robust Controls. Wahaso’s proprietary control system is custom programmed to monitor and track all system activity.
- Integrated System Design. Wahaso’s greywater processing skids are pre-assembled and integrated into comprehensive system designs that include all pumps, storage, filtration, sanitation, and controls.
Wahaso’s greywater system is fully scalable and able to process 2,000 – 200,000 gallons per day. Each standardized system includes filtration and sanitation equipment. The customizable equipment includes tanks, pressurization, and controls.

Ultra Violet Sanitation
All storage systems have a connection to a municipal source so that toilet flushing and other uses can occur even if there is not an adequate supply source of greywater. An air gap inlet can automatically be turned on to make-up water in the treated tank should a supply problem develop in the greywater harvesting system. In typical applications of a greywater system for toilet flushing, there is more than enough supply of greywater from showers and baths to meet flushing requirements.
Wahaso tank systems can be pre-mounted on skids for ease of installation with all internal piping manifolds and sensors mounted and pre-tested at our fabrication center. All of our polyethylene tanks are rated for potable water even though we are not using this water for drinking purposes.
Application of Greywater
We work closely with building engineers to properly size the pumps so that adequate pressure (PSI) and volume (GPM) is available at the farthest – and highest altitude – end point in the system.
Greywater System Monitoring And Control
In addition to monitoring the system mechanicals, the control system can track the amount of water in each tank and track and display the monthly amount of water harvested. An interface allows remote monitoring via a web page for maintenance or educational purposes. Wahaso can use the remote access to help a building maintenance staff diagnose potential system problems.
