Wastewater Treatment & Disposal...
NBU’s existing sewer system consists of over 260,000 feet of sewer lines, ranging from 8 to 27 inches in diameter. With over 800 manholes and 25 lift stations, the system now provides sanitary sewer services to almost all of the developed land within the city.

The Westside Treatment Plant was built in 2003 and has a design capacity to handle 0.499 MGD. The aveage daily load is 130,000 gallons a day. Both treatment facilities operate using the Schreiber Activated Sludge Process.
