A sewer area is part of the definition of a system of sewers in the specified area. A sewer is assumed to be present in all locations where a sewer area intersects with a sewered building.

In other words, a sewer is present if:

A sewer area can also pump stored sewer water to an external area outside the project. However, water that has been pumped out will remain in the external area and cannot be pumped back. By default sewers do not pump water to external areas.

Icon Key Unit Range Description Default value
Waterwizard icon sewer storage.png SEWER_STORAGE m The maximum water height the sewer can store. This value, multiplied by the grid cell size and the amount of grid cells marked as sewered, forms the total amount of water this sewer can store. n/a
Waterwizard icon sewer pump speed.png SEWER_PUMP_SPEED m3/s The amount of water removed from the sewer per second, by pumping it to an external area outside the project. 0
