A wastewater treatment plant cleans the water we use (sewage) so that it goes back into the water cycle without pollutants. Water we use to flush, bath, shower, and wash vegetables, clothes and dishes goes down the drain to the wastewater main in front of our homes and buildings. From there it travels through a series of other pipes to the wastewater treatment plant.  Some treatment plants are mechanical while others such as the Environmental Department's are natural.

The Environmental Department operates a regional wastewater treatment plant which consists of 460 acres of lagoons, and 240 acres of wetlands to treat and polish the wastewater. The annual average flow through the headworks is approximately 14 MGD.

This system services the communities of:

  • Logan

  • Hyde Park
  • North Logan
