Logistics Reduction: Universal Waste Management System

Metadata Updated: February 28, 2019

The objective of the Advanced Exploration Systems (AES) Logistics Reduction (LR) project[HTML_REMOVED]s Universal Waste Management System (UWMS) task is to develop a compact toilet system that can be used across multiple future crewed vehicles and habitats. The UWMS effort will result in a toilet with reduced mass and volume that provides increased crew comfort and performance. A key feature[HTML_REMOVED]of the[HTML_REMOVED]UWMS is[HTML_REMOVED]the[HTML_REMOVED]urine pretreatment dose pump/pretreatment quality indication device which[HTML_REMOVED]enables[HTML_REMOVED]water recovery from urine. The UWMS core hardware is primarily funded by the AES[HTML_REMOVED]LR project, with cost sharing from the Orion (MultiPurpose Crew Vehicle (MPCV)) Program[HTML_REMOVED]for a second flight unit, and the ISS Program for integration hardware for flying the first UWMS unit on ISS.[HTML_REMOVED]Procurement of the UWMS started late in 2015.[HTML_REMOVED] UWMS Integration and ISS planning began in 2015 and will continue through 2019 in collaboration with the ISS Payloads Office and the Orion Program.[HTML_REMOVED]The UWMS will be flown on the ISS as a technology demonstration payload in FY19. The ISS UWMS demonstration will validate the hygienic collection of urine and feces.[HTML_REMOVED] Effective collection is critical to maintain crew health and hygiene for long-duration habitats.[HTML_REMOVED] Additionally, the ISS technology demonstration will demonstrate the ability to pretreat urine and deliver it the ISS urine processor.[HTML_REMOVED] The pretreat pump and pretreat quality sensor are important components of a future long-term space habitat water recovery system. A[HTML_REMOVED]second UWMS unit will be developed to fly on the MPCV[HTML_REMOVED]Exploration Mission-2 (EM-2) mission.The waste management team collaborates[HTML_REMOVED]on a[HTML_REMOVED]Phase 2 SBIR on torrefaction of feces to assess it[HTML_REMOVED]s feasibility for space missions.[HTML_REMOVED] Additionally, the UWMS team[HTML_REMOVED]collaborates with the[HTML_REMOVED]MPCV[HTML_REMOVED]s Launch, Entry, and Abort (LEA) space suit team for contingency urine and fecal waste collection systems.[HTML_REMOVED] The LEA suit waste collection system is used if the MPCV loses cabin pressure but it may be possible to use the LEA contingency system to provide a backup for waste collection if the UWMS became inoperable.
