Cleaning up water pollution (SC3)

Contributor/author(s): Ian

I recently discovered a way to make all that scummy black water near building-polluted shorelines to go away. Here are the steps:

1. Turn the area of polluted water into land via the "level terrain" tool.
2. Build water treatment plants on that land. Attach them to your water system.
3. Go into the chart window and open the pollution window, which shows you where pollution is, and select to display water pollution.
4. Press the "Use as map" button. Now instead of having zones in the lower right hand corner, you have where water pollution is.
5. Wait until you have no white or red in the area you are cleaning up.

You may destroy the water treatment plants and build whatever you like but if you go back to water, the water will be blue, not black.
