How does flood water disappear?
After a flood, water is tediously removed from basements and other parts of homes and other structures, using pumps. The pumps either put the water in the local sewer system or out onto the ground nearby. The water that flooded streets follows gravity in the natural drainage area or watershed.
How do you drain water in cities skylines?
Drain pipes simply dump raw sewage into the water and can quickly cause massive amounts of water pollution. Water treatment plants process the sewage before dumping the water and can eliminate most of the pollution. The “eco” versions from “Green Cities” operate in the same fashion, but with reduced pollution output.

Where does the water go when a city floods?
Flood control channels are large and empty basins which let water flow in and out (except during flooding) or dry channels that run below the street levels of some larger cities, so that if and when a flood occurs, the water will run into these channels, and eventually drain into a river or other body of water.
How floods can be prevented?
Natural flood management
Measures might include using small barriers in ditches and fields, or notches cut into embankments, to divert the water into open land. Letting pools form outside the main channel of a river means the water is temporarily removed from the main flow – reducing the power of the floodwaters.
Does dredging prevent flooding?
The Environment Agency says that while dredging can improve general land drainage, it cannot prevent rivers from flooding, due to the huge volumes of water involved. In some cases dredging can even make flooding worse.
