Line 1: Line 1:
A sewer area is part of the definition of a [[sewer model (Water Overlay)|system of sewers]] in the specified area. Sewer storage is present in the hydrological model wherever the sewer area intersects with a [[Sewered_(Water_Overlay)| sewered construction]].
Similar to water level areas, sewer areas only define a sewer storage amount in grid cells that are marked as sewered. A grid cell is marked as sewered, if:
* It is covered by a construction with a [[Sewered_(Water_Overlay)|SEWERED]] attribute > 0.
* It is covered by a sewer area with a [[Sewer_storage_(Water_Overlay)|SEWER_STORAGE]] attribute > 0.
A sewer area can also pump stored sewer water to an [[External area (Water Overlay)|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.

* Water pumped out of a sewer cannot be pumped back once it is in the external area.
* Water pumped out of a sewer cannot be pumped back once it has left the hydrological model.
* The sewer pump speed may never be negative, as this would conceptually result in water being pumped into the sewer from outside the project area.

Notes

  • Water pumped out of a sewer cannot be pumped back once it is in the external area.
  • The sewer pump speed may never be negative, as this would conceptually result in water being pumped into the sewer from outside the project area.
