Central sewage treatment plant
Big, efficient and clean – this sewage treatment facility can handle up to 600 000 m3 a week, and creates no water pollution. I think it is more realistic than having to build a dozen small plants. In real life (as far as I know), even quite big cities have only one sewage treatment facility.
Requires road, electricity, and pipe connections.
The game lets you place it on land, but please place it on a shore. When running on full capacity, it spits out huge amounts of water, capable of flooding your city. (You could create an artificial river if you like…)
If the water underneath is not deep enough, the game draws a weird water pyramid next to the outlet pipe. The water somehow bounces back up from the bottom of the sea/river (?). The pyramid disappears if you make the bottom of sea deeper undeneath the pipe with terraforming tools.
Here is some comparison to the basic, small sewage treatment building:
No land or water pollution, only some noise.
Footprint: 10×10, partly on water
Cost: 25 000 (= 10 x the normal small sewage plant)
Maintenance: 5000 (= only 2x)
Sewage treatment capacity: 5x the small normal sewage plant, and almost 4x the larger one
It produces some garbage and requires two workers.
As you can see in 3rd screenshot, it could handle all the sewage of my test city with 35 000 inhabitants. The water budget was set to 100%, and there were no other sewage treatment buildings.
It doesn’t require any mods, props, or DLCs.
