Naperville's Wastewater
Wastewater from Naperville and Warrenville flows through sanitary sewers to the Springbrook Water Reclamation Center located south of 95th Street along Plainfield Naperville Road. At Springbrook, wastewater is taken through a series of steps to treat, filter and disinfect the water. The treated water goes into the DuPage River and the solids are recycled into a nutrient rich fertilizer called biosolids. Springbrook processes over seven billion gallons of water each year and produces about 2,000 dry tons of biosolids.
