Based on experience obtained in operation of the water and oxygen recovery systems installed onboard the Russian space stations Salut, Mir and the International Space Station ISS, data on the water and oxygen balance for a space station are presented as well as operational parameters and performance data of the systems. Using the data obtained design analysis of an integrated life support system for water and oxygen recovery based on physical/chemical means to be installed on a promising space station is carried out. Mandatory verification tests of new process (technologies) and recovery systems are to be conducted on ISS.

The paper summarizes the experience gained on the ISS water management system during the missions of ISS-1 through ISS-16 (since November 2 2000, through December 31, 2007). The water supply sources and structure, consumption and supply balance at various phases of space station operation are reviewed. The performance data of the system for water recovery from humidity condensate SRV-K and urine feed and pretreatment system SPK-U in the Russian orbital segment are presented. The key role of water recovery on a board the ISS and the need to supplement the station's water supply hardware with a system for water reclamation from urine, water from a carbon dioxide reduction system and hygiene water is shown.
