Water Sieve uses a Filtration Medium to pollute Water and Crushed Water. It needs to be supplied with Polluted Dirt and receive Water in a Liquid Pipe on its Input port to function. It will output Polluted Water to the Liquid Pipe on its output slot if Water is input, and Crushed Polluted Water if Crushed Water is input. It will drop Sand on the floor when its internal storage is full.

The Water Sieve does not change the temperature of the water.

Usage[]

The Water Sieve is a very helpful building as Polluted Water is a very important resource. It allows a colony to operate structures like the Carbon Skimmer or the Lavatory without consuming polluted water by instead consuming polluted dirt which is far more abundant. Water Sieve is required to make use of the Water found in any of the starting Biomes.

Ratios[]

  • 1 constantly running Water Sieve can process up to 3 tons of water per cycle. This can supply 300 combined Lavatory and Sink uses per cycle, or 100 Shower uses.
  • 2 Water Sieves are needed to pollute a full pipe of Water.
  • 1 Sieve can filter 5 active Carbon Skimmers.
  • 2 Compost piles are needed to purify the Sand from 1 active Sieve.

Tips[]

  • If a Water Sieve is out of Polluted Dirt, it will stop receiving any liquid from its Intake Pipe.
  • A Water Sieve will not be damaged by Polluted Water, Salt Water, or Brine. It will simply pass it along and does not change its temperature.
  • Luckily, polluting Water does not remove any germs contained in it. So be sure not to filter your main water supply and waste water using separate Sieves. Germs in a Water Sieve will proliferate and spread to any future water filtered.
  • Polluted Water contaminated with Slimelung will override Food Poisoning when combined in the same storage. This can be achieved using an Algae Distiller with Slime, or by having a Duplicant covered in Slimelung use a Sink.
