The City of Newport operates a modern and up-to-date wastewater treatment facility. Two treatment facilities serve the needs of industry, business and residential customers. The City of Newport completed renovations to the Airbase Industrial Park treatment facility in 2004 and a 2.3 million dollar renovation project on the main sewer treatment facility in 2010. The City of Newport now has a three million gallon capacity per day system. All of this work was accomplished without an increase in sewer rates, which remain among the lowest in the state.
