Water Purifier are one of the building structures that is mainly used to collect Clean Water and Dirty Water. It is an upgraded version of the Draw Well capable of gathering huge amount of water in a single go. However, the materials needed to fuel up the purifier is rather costly so its best to have enough inhand to avoid losing possible profits when mass crafting items.

The building is also a pre-requisite for constructing Greenhouses.


Water Purifier's schematics is available once survivors reach level 75. Its crafting recipe could then be unlocked in-exchange for 3 Research Points.

Note: When building the furnace with Welder and Generator, it is recommended to keep the generator's use down to 10%. By doing this, survivors can maximise their use and save more resources compared when assembling new Generators.


Once the Water Purifier is built, survivors can finally start collecting either Dirty Water or Clean Water. The structure has 100% durability before it needs to be refuelled again. At maximum, survivors can get more dirty water compared to clean water.
