Aqua Engineers upgraded Digester #1 at the Schofield Barracks Wastewater Treatment Plant to increase its efficiency and minimize its environmental impact. The 280,000 gallon digester received a fixed cover and a flexible mixing system to provide operations a variety of suction and discharge configurations.

This project evaluated alternative techonologies including cogeneration using microturbines and the use of a F.O.G. (fats, oils, and grease) receiving station.
