Pump area (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	PUMP_AREA	boolean	0 to 1	When true the Pump is spread across the entire building surface.	0

• 
  A pump consisting of one line area, with one entry point for the lower and one for the upper Water level areas. It uses a single cell to subtract water, which may be insufficient for high flow rates.
• 
  The base type overlay indicating that only one cell is used to subtract water from.
• 
  A pump consisting of two separate areas, one for the lower and one for the upper Water level areas. It uses a lower level threshold and requires multiple grid cells to subtract enough water. It is configured as a PUMP_AREA.
• 
  The base type overlay indicating that this pump now uses multiple cells to subtract water from.

Notes

• Selecting this option is useful when the PUMP_Q value is too large for a single cell.
• This requires the pump to consist of 2 discrete polygons. This can either be as a single section with 2 seperate polygons, or as 2 seperate sections with 1 polygon each.

Troubleshooting

• Troubleshooting lower threshold for pump is not reached
