The treatment plant was developed on a 15-acre tract of land with an initial treatment capacity of 3.1 million gallons on an annual average.  
  

In its current configuration, the facility has three primary clarifiers with four aeration basins, three secondary clarifiers and two chlorine disinfection chambers.
