The Wastewater Treatment is the sole machine which can process Waste Water. Upon initially being unlocked it can only use Sand as a filter, but with the subsequent Wastewaste Treatment II research it can also use Filter Media as a filter for improved Water recuperation. Later it gains the ability to process Toxic Slurry. The Sludge output can be reprocessed into Fuel Gas and Compost or burned away.
Below are all the recipes, which this building is capable of producing. Note, that some of them may be locked behind Research, and not immediately available in your game.
