Treatment Process

Wastewater is reclaimed through natural processes, which are accelerated using electrical power and computer-controlled equipment.

  1. Wastewater is simply placed into a large tank so grit and heavy particles can settle out by gravity, leaving dissolved materials in the water.
  2. Settled wastewater is mixed with bacteria that are able to remove dissolved materials from the water. The bacteria convert dissolved materials into more bacterial cells.
  3. The bacterial cells are removed from the water by gravity settling and by disinfection.

The reclaimed water is discharged to the Arkansas River, where it supports a variety of beneficial uses such as aquatic life and agricultural irrigation.
