This paper reviews the design and properties of the Water Supply System (WSS). It also discusses the water balance and its delivery amounts, as well as it presents diagrams and properties of water recovery system from humidity condensate WRS-CM and regeneration from urine WRS-UM which are the part of WSS. Some results of activities conducted for provision of water intake in a system of WRS-CM from different modules of station are shown and the problems of WSS interaction of Russian segment (RS) and American segment (USOS) of the International Space Station (ISS) are discussed.
