Navajo Mountain Water Reuse Project

Fully biological & autonomous water reuse system


CleanBlu was chosen by The International Water, Sanitation and Hygiene Foundation (IWSH) together with the IAPMO Group to design and manufacture a low cost, fully autonomous water reuse system for the new Naatsis’áán (Navajo Mountain) Chapter House in Piute Mesa, Arizona. Toilet flushing consumed ~50% of their total water usage and so the challenge was to design a system that could treat and recycle that water inside the septic tank and continuously reuse it. CleanBlu is proud to have provided Navajo Nation with a low maintenance 4-stage aerobic biological treatment system, achieved without sterilization and using only oxygen and microbial management to treat the wastewater for reuse. The system is fully autonomous and is managed via the CleanBlu Connect app.
