LEE & RO provided process analysis, engineering, design and construction management & resident engineering services for a $25 million plant upgrading project for the 5.9 mgd WWTP.  Prepared project reports, which led the City to successfully obtain $15 million from the CWSRF and a $10 million ARRA grant.  Project components included an activated sludge complete with nitrogen removal, UV disinfection, and sludge dewatering / drying.  The solids train consists of gravity thickening, centrifuge dewatering, and solar greenhouse drying.  The ARRA grant was partly based on the energy-saving, solar greenhouse for production of Class A Biosolids.  This project received “Project of the Year” award from the San Diego / Imperial County Chapters of the American Public Works Association in 2012.
