ACEC California Member Kennedy/Jenks Consultants has been recognized with an Engineering Excellence Honor Awards for their Central Marin Sanitation Agency project in Marin County. The intent of the Awards is to recognize outstanding achievements in engineering and land surveying projects completed by California firms.
Kennedy/Jenks Consultants – Central Marin Sanitation Agency
Food scraps and Fats, Oil and Grease (FOG) are being converted to renewable energy at the Central Marin Sanitation Agency wastewater treatment plant through an innovative design. This pioneering design upgraded the plant’s anaerobic digesters and included the installation of a new facility to receive and screen food waste/FOG and then feed the blended waste stream to the digesters to produce additional methane biogas and electricity at the plant.
Currently, over twenty tons of food scraps (waste) are diverted from the local landfill per week. Once at the plant, this waste is slurried before being digested to methane biogas by the anaerobic digesters. Additionally, 10,000 gallons per day of FOG are also digested. The current daily average of methane biogas produced has increased by 50% (100,000 ft3). This increase in methane biogas production allows for the plant’s generators to increase their run time from a historical average of 8-9 hours per day to approximately 16 hours per day.
Project entries are accepted into one of 12 project categories. The Honor Award winning projects will have photographic panels on display at the State Capitol, outside of the governor’s office, in early 2015.
“Every day these firms work in collaboration with public and private sectors and state and local agencies to help build a better California,” said Brad Diede ACEC California Executive Director. “It’s with great accolade that we honor their work.”
