Atlanta Cogeneration Facility Design/Build Wins Project of the Year
(ATLANTA, GA – Nov. 27 2012) – The Georgia Chapter of the American Society of Civil Engineers has bestowed the 2012 Small Project of the Year award to the City of Atlanta Cogeneration Facility Design/Build Project.
Hazen and Sawyer was the design engineer for the project, which was focused on energy-efficient upgrades to the R.M. Clayton Wastewater Treatment Plant, one of the largest wastewater treatment facilities in the Southeast with a permitted capacity of 120 million gallons per day (MGD) and current average flow of 80 mgd.
The design-build co-generation project provides equipment and systems to beneficially utilize digester gas to operate an engine generator in a combined heat and power (CHP) system. The electrical power produced is used to offset the plant’s purchased power usage, which decreases purchased power costs, decreases the plant’s carbon footprint, and helps the City reach their renewable energy goals. The thermal energy recovered from the engine generator jacket and exhaust gas heat recovery equipment is used to heat water and provide process heating for the anaerobic digesters.
Our design/build team developed an innovative approach to repurpose an abandoned gas control building to house the new generator, saving the City significant capital costs and improving access and maintainability of the new equipment.
The project was delivered on schedule and on-budget and was completed in March 2012.
Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
