Water is one of the most important Resources in the game. Water is necessary for making food and supplying Oxygen, but does not need to be directly consumed by Duplicants for survival (despite its description).

Production[]

Fresh Water can be obtained by filtering Polluted Water using a Water Sieve, melting Snow or Ice or cooling Steam. It can also be generated by boiling Polluted Water or Salt Water and then collecting and cooling down the steam.

  • Duplicants with the Ugly Crier stress response will produce copious amounts of clean water during their mental break.

Usage[]

  • Pitcher Pump bottles water from open water source to be used in certain buildings.
  • Farming:
    • Bristle Blossom domestic growth requires 20 kg/cycle Water irrigation.
    • Sleet Wheat domestic growth requires 20 kg/cycle Water irrigation.
    • Oxyfern domestic growth requires 19 kg/cycle Water irrigation.
  • Inside the Apothecary, Duplicants with Medicine Compounding skill can produce Curative Tablet from Coal and Water.
    1 kg Coal + 1 kg Water = 1 unit Curative Tablet.

Tips[]

  • Too much water in an area can damage tiles with high pressure which can cause flooding or escape of the liquid.
  • In most asteroid types, if there is a frozen biome it starts well below the salt water/brine conversion temperature. Piping salt water in is a good way to generate ice from the SW/Brine conversion, as well as cold water/polluted water from the biome's own meltwater. Both the solid and liquid water can then be carried/piped away and used for early game ("Plumbing" is the only required tech) temperature regulation. The brine can be used to create salt or as low-freezing temperature coolant once more advanced technology is researched.
