Over time satisfying thirst and hunger of Stationeers will cause them to need to relieve themselves. The ODA recommends that Stationeers set up a Modern Toilet within their base after landing, requiring an atmosphere and Water to operate. This will output Polluted Water which can be recycled using a Water Purifier and then used for other purposes, such as farming or drinking. The Waste Bag can be used as a portable alternative to the toilet but the contents are not recoverable.
