The Cliffside Bay map provides access only to a small stretch of water in a bay at the start of the game. How can I deal with water pollution here? I'm relatively new to the game.
Originally I put the drain pipe on one extreme of the bay and the pumping station on the other extreme. Of course the pollution keeps spreading in the bay, threatening to reach the water pump. Later when I could buy more land, I bought two squares to the west, built a long pipe, and drained the sewage by the beach on the other side of the map. I removed the original drain pipe, hoping that the pollution will eventually just go away. But it doesn't go away. I keep watching it as it slowly slowly inches towards my water pump and will probably eventually kill the city.
I remember reading somewhere that water pumps can be used to remove polluted water. So I built one with a corresponding drain pipe and a separate pipe circuit far from any buildings. But the new circuit is not operating. It has electricity but it seems it won't do anything unless some buildings are connected.
So what's the solution here? Will it be necessary to use water towers exclusively and put up with the main waterfront being all brown?
