Trinity River Authority’s (TRA) Central Regional Wastewater System (CRWS) plant began operations in 1959 as the first regional wastewater facility of its kind. The system is now one of the largest in Texas and has expanded to serve approximately 1.2 million people, providing treatment for 162million gallons a day (MGD). The treatment process removes 99% of conventional pollutants from raw wastewater and can handle daily maximum flows of 335 MGD and two-hour peak flow maximums of 405 MGD.
In 2017, MWH was awarded the contract to provide construction and startup and commissioning support for the Phase III-B Solids Management Improvement project for the CRWS. This project will replace the lime stabilization process with the Cambi® Thermal Hydrolysis Process (THP), an innovative solution to wastewater management that produces higher quality biosolids while capturing and treating odors more effectively, and maximizing biogas utilization to produce heat, steam, and energy. MWH has significant expertise in the design, construction, and commissioning and start-up of CambiTHP™ systems. Out of 50 CambiTHP™ systems currently installed worldwide, MWH provided services on more than twenty.
"It is a tremendous privilege to be selected by TRA for this important project. MWH is committed to providing superior service, and we look forward to partnering with TRA for a project that will meet the needs of the community for years to come."

Lance Ota, Project Manager, graciously accepted the award on behalf of the team.
Read MoreMWH is continuing to work uninterrupted on the Biosolids Digester Facilities Project (BDFP). The long-term, large-scale 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.
