Net Zero Water Projects at Fort Riley, Kansas
Located in Kansas, Fort Riley was selected for the Net Zero Water pilot project. Through participation in this project, Ft. Riley aims to reduce water demands and improve operational capabilities to enhance mission effectiveness. Addressing water security and sustainability is operationally necessary, financially prudent, and essential to mission accomplishment. The following are three projects to improve sustainable water use practices:
- Water Reuse - Today, we use drinking water for all of our household water needs; taking showers, washing our cars, watering our lawns, and even flushing our toilets. Traditional water treatment is very expensive and uses a lot of energy. Additionally, towns and municipalities typically use a single water treatment facility. At Ft. Riley, EPA scientists and engineers are installing and testing different “sewer mining” systems for treating and storing water. By tapping into a wastewater collection system, sewer mining siphons some of the sewage to a treatment facility and reuses the reclaimed water for irrigation and other uses not suitable for drinking. Through other tests and comparisons, in partnership with the Department of Defense (DoD) Environmental Security Technology Certification Program (ESTCP), the EPA will be able to share the data with Ft. Riley, DoD facilities, and the general public. This findings from this project will be useful to those who are selecting alternative approaches for reducing water consumption and energy use.
