Clean water is not free. This mod adds three tiers of natural water processing recipes to Krastorio2. The processing requires water filters, which has mechanisms similar to air purificator.
This small mod is intended to add some flavor to your factory. It shouldn't be difficult to integrate water processing plant with your normal K2 gameplay. It is tested with and without Space Exploration installation.
This mod makes the offshore pumps to produce "raw water" instead of normal water. It is advised that you remove all the offshore pumps before applying this mod to an existing save data.
