MWH was the CM/GC for this award-winning project, construction of a new 30-mgd plant as an upgrade to the existing facility, with a combined daily average of 60 million gallons per day (MGD) and 120 MGD peak capacity. The project included all new: headworks facility, raw sludge pump station, two primary clarifiers, aeration basin and blower building, four secondary clarifiers with RAS/WAS pump station, chlorine contact basin, utility water pump station, a dichlorination building, two anaerobic digesters and digester control buildings and a sludge thickening building.
MWH was selected by CWSID based upon seasoned expertise and knowledge of the CM/GC delivery method. MWH provided value through identifying solutions to the challenges of constructing within an operational facility. This expanded treatment plant was designed to improve flexibility in treatment and operation to meet the expected changes to the discharge permit requirements in the future. Essentially, a new parallel treatment plant was constructed so that both could be operated independently or together.
"I would like to give my sincere recommendation of the MWH Constructors Team for completing this project on time and under budget. The project team was responsive to our needs and worked in partnership with Central Weber to ensure our goals were met."
This $110M Construction Manager-at-Risk (CMAR) project was awarded to MWH by the North Texas Municipal Water District. It consists of four phases and requires the coordination of three separate design teams (Jacobs, Carollo, and HDR).

MWH is continuing to work uninterrupted on the Biosolids Digester Facilities Project (BDFP). The long-term, largescale project represents a significant overhaul of the Southeast Treatment Plant, San Francisco’s largest wastewater pollution treatment plant. BDFP is set to redefine the way wastewater is treated in the city, aiming to process up to 800 million gallons per day (MGD) and serving about 80% of the city’s population. Implementing state-of-the-art technologies and innovation, the project underscores MWH’s commitment to environmental sustainability and urban rejuvenation. The revamped plant will set new standards in waste management and pollution control, marking a major milestone in San Francisco’s environmental management history.
