Sewer overflow (Water Overlay)

Sewer overflows are points where water is moved from the sewer to the surface water system. A sewer overflow will allow water to flow through if the water in the sewer exceeds the SEWER_OVERFLOW_THRESHOLD, and the water in the connected sewer exceeds the height of the terrain at the location of the sewer overflow. It will then allow water to flow out of all sewers part of that sewer area.

A sewer overflow is a point-based construction. It must intersect with a sewer area and a water level area, but does not need to intersect with an actual sewered construction. Template:Overlay attribute

Note

• At most one overflow can exist per sewer area.
• Water will flow when the water height in the Sewer is larger then the SEWER_OVERFLOW_THRESHOLD.
• Sewer overflows can be generated along with sewer areas in the configuration wizard. They will be generated in the first water terrain which is covered by a sewer area and a water level area.
