Old water pump

A water pump from the 60s - built between blocks of flats in People's Republic of Poland (when Poland was behind the Iron Curtain). The water is deemed unsafe for humans to drink, but it can be used to water the plants, etc. Mostly the reason for making this kind of water pumps between block of flats was due to cold war - many blocks had an atomic shelter (with air and water purification equipment, heavy steel doors with lead inserts) and those that didn't have shelters still got decent concrete basements, that could withstand great deal of damage. And if not hit directly or really close - people could probably survive hiding in those basements. In general, any survival guide says you should keep away from the fallout for two weeks and minimize leaving shelter/safehouse during that time. Radioactive decay would make it 'survivable' by that time (not perfect, but hey). Now - everything will be contaminated, but groundwater should be pretty ok, so having water pump might have meant survival.
