NASA is advancing its plans for sustainable human presence on the Moon and Mars with the testing of the Divergent Deployable Wastewater Treatment Facility. This mobile system, developed at NASA’s Kennedy Space Center in Florida, is designed to convert crew wastewater into valuable resources necessary for long-duration missions.
On April 21, 2026, the facility was transported to the University of North Dakota in Grand Forks, where graduate students will evaluate its performance under conditions that simulate the challenges of extraterrestrial environments. The facility will be integrated with the university’s Integrated Lunar/Martian Analog Habitat, allowing researchers to observe how it operates in a habitat-like setting.
How Treatment System Works
The facility is housed within an 8.5-by-24-foot trailer and incorporates multiple components: three biological reactor systems, a vertical garden, water-polishing hardware, environmental monitoring, autonomous control software, and safety systems. This setup is crucial for facilitating the treatment of wastewater from small crews, which can be highly concentrated.
By separating waste streams—such as urine, hygiene water, laundry water, fecal waste, and food waste—the facility employs three distinct bioreactors tailored for specific waste types. The Anaerobic Phototrophic Membrane Bioreactor processes fecal and food waste, converting it into nutrient-rich wastewater suitable for plant growth. The Suspended Aerobic Membrane Bioreactor handles urine and flush water, while the Membrane Aerated Biological Reactor treats graywater from hygiene and laundry activities. Together, these systems will support the vertical garden, where crops will be grown hydroponically using nutrient solutions derived from the bioreactors.
Testing and Future Integration
At the University of North Dakota, the facility will be connected to the habitat through a bathroom interface featuring a urine-diverting toilet. This setup enables the separation of waste streams at the source, directing them to the appropriate treatment systems. Additionally, researchers are developing novel membrane-based separation technologies to enhance water recovery efficiency and system resilience.
“The tests will help NASA evaluate real-world operation, crew training needs, system reliability, and how wastewater simulants compare with actual human metabolic waste in an analog mission environment,” stated Ali Alshami, a key researcher in the project.
Implications for Lunar and Martian Habitats
This initiative is part of NASA’s broader Bioregenerative Life Support Systems effort, which aims to reduce reliance on Earth-supplied consumables. The wastewater treatment facility could play a vital role in closing life support loops by recovering water, recycling nutrients, and supporting crop production in future lunar or Martian habitats.
NASA’s ongoing research indicates that bioregenerative life support systems may offer enhanced effectiveness for space travel compared to current technologies. The agency is also exploring how resources recovered from wastewater could facilitate in-space manufacturing, including the production of materials like polylactic acid for 3D printing.
“By moving this facility from NASA Kennedy to North Dakota, we are transitioning a crucial component of our circular economy from the lab to real-world testing,” remarked J.J. Edelmann, surface systems domain lead for the Mars Campaign Office. This work not only focuses on wastewater but aims to enable future crews to live sustainably on the Moon and beyond.
