The Soviet Union's striving for being the first in everything let the country go down in history as the leader in space exploration. It created laboratory complexes which although became outdated are still fit for use. However, many of them will never make it until modernization. This report is about one of such labs, still alive but doomed for "extinction".
In order not to deliver tons of water to space stations, they equipped it with special filtering devices processing cosmonauts’ urine and water vapor found inside the station to turn them into drinking water. In case one of such devices breaks down, the station features a water reservoir. Let’s see where they make water for it.
They filter water with special silver filters which kill harmful bacteria. Silver-filtered water remains fresh for a long time.
There are a bunch of pipes in the lab.
