||“Stockpile supplies before the water shut-off.”
|— In-game description
A rain collector barrel is a craftable water container.
Rain Collector Barrels are used to collect rainwater, and take up one tile space. When it is raining, they will convert the rain into usable water. They are an alternative to the well or a body of water, such as a river or lake, in gathering water after the waterworks shut down. The collected rainwater will be tainted and unsafe to drink and must be purified by boiling it in a heat source but can be used to water plants without needing purification. The lesser collector requires level four Carpentry to build, and the bigger collector requires level seven Carpentry. The smaller collector stores 160 units of water and the larger stores 400. There is also a metal drum barrel which can currently be found at the camp site around Louisville which holds 800 units. It is not (yet) possible to craft the Metal Drum without installing mods.
A rain collector barrel can supply water to up to 8 plumbable entities (such as sinks, showers, baths) on the floor below it providing they are situated directly under the tiles around the water barrel. Anything placed directly underneath the barrel will not be plumbable. Note that the room in which the plumbable entity is placed must be fully enclosed with walls before the option to plumb becomes available, i.e. you can't just build a "roof" above a sink and place barrels on it.
Before build 41 the Wrench was needed instead of the pipe wrench for Plumbing a sink, which effectively rendered the pipe wrench redundant. However, this was resolved in build 41.
