It can be further purified by boiling and distillation, which can also be accomplished with fire and simple tools. Your autarky is better off than some rural African villages if you can source clean water locally without having to physically retrieve giant, heavy vessels of surface water. The entire society revolves around this most fundamental resource. It's used for survival, hygeine, cooking, raising animals, primitive crafts, and much more.

Picrel is a simple water filter. It's just charcoal, gravel, and sand, which is free. You can expand this on a larger scale for rainwater and storage, which is safe when boiled/distilled, but much better when purified as well. Gets out any chlorophyll or sediments, so it's just clear, pure fresh water. A lot of people use an underground or above ground tanks and a pump to have an independent water system that is off the grid, or as free water to save money.
