Wastewater Treatment

Shelby Wastewater Treatment Plant

The Shelby Wastewater Treatment Plant is a Class 3 facility and processes about 1.9 million gallons of wastewater per day with an annual volume of 800 million gallons. The city has over 70 miles of sewer lines and 1,300 manholes that make up the collection system. The Shelby Wastewater Treatment Plant uses an activated sludge process, in which micro-organisms and oxygen are combined to break down solids. Only two chemicals are used in the process. Chlorine gas kills a disease-causing bacteria, and sodium bisulfate is used to remove all chlorine before the final product is released to the Black Fork River. In many ways, the treated water is cleaner and healthier than what flows in the river today.
