Hi, I am new at this mod and I have a small problem. I thought it is best to place it as a comment instead of a discussion: I just have built some structures from this mod. I already have laid out my toilet/bath room, all is done except the toilet/bathes itself (already installed the pipes to the sewage output). Now, I have built a water well + electric pump and a water tower. These are NOT connected to the bathroom yet. I started to fill the water tower. However, it reads "Quality: untreated - small disease risk". But there is no pollution around?

The sewage outlet is way past this screenshot, somewhere in the west (also goes out in the river). but that does not matter because the water tower is not connected to my facilities yet.

So, how can I fix it?
