Water
From The Forever Winter Wiki and Guides
The Scav's secondary goal, in addition to the current mission that Scavs have set for themselves, is to acquire water, which occupies a large item slot.
This type of barrel is designed based on existing plastic barrels used for various substances.
Water can be obtained either through missions or randomly found in various locations across different maps.
As of the 2024 October Update, water can be stolen from other players from their Innards
