Because Unidirectional Flushing is more effective at getting the pipes clean, we're able to flush less often. And because the pressure and velocity used in UDF is so much higher than traditional flushing, we actually run the water for a shorter duration. Our flushing schedule is also designed to ensure that we never unnecessarily flush an area.
Any water that is discharged is returned back to the river through our storm systems. To that end, the water is returned to the water cycle.
