Schofield Barracks Wastewater Treatment Plant Digester Rehabilitation



In 2011, Aqua Engineers was awarded this $3 million contract by the US Army Garrison Hawai‘i DPW.  The goal was to provide ongoing equipment repair and replacement at the Schofield Barracks Wastewater Treatment Plant Digester in order to increase its efficiency and minimize its environmental impact. 
The project also includes researching potential additive alternative waste to energy projects. These alternative energy projects include cogeneration using Combined Heat and Power System technology and a F.O.G. (fats, oils, and grease) receiving station.  
In addition to job creation, this project will result in alternative energy sources.  The cogeneration system uses waste gas to produce electricity, which will reduce emissions associated with fuel oil, and cut back on electrical consumption.
The second alternative energy project—F.O.G.—will retain oils, greases, and fats from the digester and use them to create methane gas production that can be used to make additional electricity.
