Clean water sources

[Falcon9a]

So far I've found the sinks and heard there's a clean water fountain in Flathill. Anyone found other sources of clean water yet?

you can boil the tainted water in an cooking pot to get clean water.

In later areas there are large water tanks, you can bring a barrel and bucket to fill up and take back to base. There's also an antejuice pool that (for now) acts like clean water - get a barrel of that when you can. I'm not aware of any other renewable clean water (until you get a filter)

Sinks (very) slowly refill water, but definitely don't rely on this, as it's more of an edge-case mechanic.

Boiling is your primary source of potable drinking water until containment labs, unless you're willing to do your refills at the antejuice pool in manufacturing.

Antejuice (see above) is clean by default and always safe to drink from, but is a bit annoying to get and is inaccessible in offices.

In containment labs, you will learn a recipe for a purifier barrel (assuming you remembered to pick up a barrel from manufacturing) which will make the prior two sources largely irrelevant. This is currently the best way so far, but it is towards the end of the content currently available.

One large water tank (12 L) in Manufacturing nearing the blast door entrance to the radioactive area, the other one in Science is also 12 L (but by that point water shouldn't be a problem anymore)
