How the DOE Saves Water

The U.S. Department of Energy’s Moab UMTRA Project in eastern Utah demonstrates a successful water efficiency and conservation initiative by switching to waterless urinals across its Moab and Crescent Junction sites.

Key points:

  • Phased implementation:
    The project gradually transitioned from low-flow toilets (2002) to waterless urinals, starting with a pilot in 2015 and completing full adoption (17 units) by 2021.

  • How the technology works:
    Waterless urinals use a cartridge and biodegradable sealant to direct waste, block odors, and prevent bacterial reactions—eliminating the need for flushing water.

  • Major impact:

    • Over 80,000 gallons of water saved annually

    • Significant wastewater reduction (~76,500 gallons)

    • Low operating cost (under $900/year total)

    • Quick return on investment (within 12–18 months)

  • Efficiency gains:
    Each urinal saves about $875 per year, with minimal maintenance required.

  • Broader significance:
    The project serves as a scalable, cost-effective model for water conservation, especially in water-scarce regions like the American West.

Bottom line:
A simple, low-cost technology shift led to substantial environmental and financial benefits, making it a strong example of practical sustainability in action.  That’s pretty much what waterless urinals are all about.
