A major $13 million upgrade earned the City of Oakdale (California) Wastewater Treatment Plant recognition as the Treatment Plant Upgrade of the Year from the state of California and American Society of Civil Engineers. 

The improvement project added lining to the aeration ponds, a large clarifier, tertiary filtration, UV disinfection and two Huber screw presses for dewatering. It was a bit of overkill, though, as the facility has a 10 mgd capacity with an average flow of 1.5 mgd.
