In Once Human, polluted water is a resource you can find in specific areas. It’s not suitable for drinking, but it has its uses. It’s a key ingredient for making Acid, which is used in many crafting recipes. With the Stardust Water Pump, you can turn polluted water into Stardust Source. But where can you find polluted water? Here’s where to look.

Once Human – Polluted Water Location

If you want to set up an Acid or Stardust farm, you’ll need a lot of Polluted Water. Therefore, your Territory should be in a polluted zone. Here are several locations where you can find it:

1. Blackfell in Red Sands: There’s a huge lake on the east side of the city containing contaminated water.
2. Blackfell Oil Fields in Red Sands: The whole fields are contaminated.
3. Evergreen in Iron Red Sands: There’s a polluted river on the west side of this town.
4. East from the White Cliff in Blackheart Region: The whole area surrounding the hill is polluted.
5. The area north from the Alternate Reality Research Institute: Shoreline is filled with polluted water.
6. The north-west zone in Chalk Peak: All water reservoir at that corner is polluted.

Once you’ll see a notification on the screen that says, ‘The Stardust pollution is getting worse…’, you’re in the right place. To extract polluted water from the ground, you’ll need a Water Pump, which can be unlocked through the Memetic System. To build it, you need to gather the following materials:

1. Steel Ingo x25
2. Carbon Fiber Fabric x20
3. Refined Parts x20
4. Standard Parts x20
5. Electronic Accessory x20

Remember to build the Water Pump directly on the ground, not on a foundation.
