NBU's wastewater (sewer) distribution and collection 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 provides sanitary sewer services to almost all of the developed land within the city. The distribution system's number one goal is to get any sewer and even rain runoff from the roads to a facility for treatment. Wastewater treatment is the process of cleaning used water and sewage so it can be returned to the envi­ronment. The process is crucial to protect public health by eliminating bacteria and viruses from wastewater. This also protects our water supplies like oceans, lakes, streams and rivers.
