Resposta rápida
Use Treatment Tablets on untreated water. They sit in the bathroom mirror cabinet on Night 0 and turned up again on Day 6 next to the water bottles. Tap water you store on Night 0 shows as clean; the game flags rainwater as untreated. We haven't seen the tablet-use prompt itself on screen yet, so we can't give the exact button.

Where to find Treatment Tablets
In the 7 Tips video the tablets are in the mirror cabinet in the bathroom on Night 0. On Day 6 in a longer run they were picked up again on a shelf next to the water bottles. Grab them early, because the Day 2 objective is to fill every container before the taps stop and the tablets are what you need for water that is not from the tap.
Why rainwater needs treating
The Day 6 objective is Collect rainwater: you set an open bucket on a balcony bracket, and the game adds that rainwater is untreated. That is the only water we have seen the game call untreated, and it is what the tablets are for.
Telling clean water from untreated
The item panel shows the state of what you carry: a Cleaning Bucket picked up on Day 2 read 10.0 L clean, and the Sealed 2 L Bottle is shown as clean and safe to drink. Check the panel before you drink. For the order of storing water on Night 0, see the food and water page.
Tips
- Keep Treatment Tablets with your bucket.
- Fill every container with tap water before the taps stop (the Day 2 objective).
- Read the item panel for clean or untreated before you hold F to drink.
