Abstract
The ISS Water Recovery System (WRS) includes the Water Processor Assembly (WPA) and the Urine Processor Assembly (UPA). The WRS produces potable water from a combination of crew urine (first processed through the UPA), crew latent, and Sabatier product water. The WRS has been operational on ISS since November 2008, producing over 21,000 L of potable water during that time. Though the WRS has performed well during this time, several modifications have been identified to improve the overall system performance. These modifications can reduce resupply and improve overall system reliability, which is beneficial for the ongoing ISS mission as well as for future NASA manned missions. The following paper lists these modifications, how they improve WRS performance, and a status on the ongoing development effort.
