Wastewater Services

The City of Modesto owns and operates two wastewater treatment facilities. The facility Located at 1221 Sutter Avenue provides primary treatment by removing solids from an average of 20 million gallons of wastewater per day.  Flow from the Sutter Avenue Plant travels about six miles through two pipelines to the treatment facility located at 7007 Jennings road. The Jennings Road facility provides secondary and biological nutrient removal (BNR)/Tertiary Treatment to an average of 15 million gallons per day.  After Secondary treatment the safe water is delivered to the almost 2500 acre ranch to be used as irrigation water. The water treated at the Tertiary facility is deposited in the San Joaquin River, and soon a portion will be delivered to the Del Puerto Water District via the Delta Mendota Canal.
