You’ll feel the pressure of hydration almost immediately in Green Hell. Water isn’t just a stat to manage—it dictates how far you can explore, how long you can fight, and whether you survive the night. Below is a complete breakdown of every way you can get water safely, starting from day one.
How hydration works in Green Hell
Your hydration meter constantly drops as you move, fight, or work. When it hits zero, stamina drains rapidly, health starts falling, and survival becomes a countdown. While water is everywhere in the jungle, most of it is unsafe and carries parasites unless treated properly.

All water sources in Green Hell
Below is a list of all the water sources in Green Hell. Make sure to note which is safe to drink:
| Method | Clean water | When to use | Risk |
|---|---|---|---|
| Fresh coconut | Yes | Early game | None |
| Rainwater in bowls | Yes | Early–mid game | None |
| Boiled river water | Yes | Early game | None |
| Water filter | Yes | Mid game | None |
| Water collector | Yes | Mid–late game | None |
| River or pond (direct) | No | Emergency only | Parasites |
How to boil unsafe water
Most rivers, ponds, and streams contain unsafe water even though it is readily available. Boiling removes all parasites, thus making it safe to consume and reducing the risk of losing health. Here is how you can boil water:
Step 1
Fill the container with water from a river or pond using a bidon or by interacting directly.

Step 2
Build a small fire using the hand drill and put the dirty water bidon near the fire. Wait for the boiling process to complete.

Drink the now-clean water or pour it into another bidon for storage. This method is essential until you unlock advanced water structures. You can repeat the same process using the Turtle Shell to collect dirty water and then boil it.
Drinking unsafe water and parasite risks
In emergencies, you can drink directly from rivers or ponds. This usually causes parasites, which drain nutrients over time.
Parasites can be treated by consuming specific mushrooms, but relying on this method repeatedly is risky and inefficient. Treat unsafe water as a last resort, not a habit.
