Drainage active (Water Overlay)
|DRAINAGE_ACTIVE||boolean||Whether the drainage is actively pumped.||False|
An actively pumped drainage will be able to move groundwater into the open water, even if the surface water level is higher than the ground water level. A passive drainage effectively just allows water flow based on water head differences.
