Alder Construction has worked on this Wastewater Treatment Plan over 25 years ago. We returned in the summer of 2005 to expand the existing plant to be able to handle 10.0 Million Gallon Per Day (MGD). This project included construction of a new pumping station, a new 2.0 MGD oxidation ditch system, two new 80' diameter clarifiers, a new 2-Story, 4,900 square foot sludge processing building with equipment, renovation of the existing 2.2 MGD oxidation ditch and renovation of the existing anaerobic digester complex. The completed work also involved associated piping, electrical, and mechanical work. Total project cost was $9,996,400.00 and was completed in the summer of 2007.
