SDSTA Wastewater Treatment Plant

The SDSTA Wastewater Treatment Plant (WWTP) Rotating Biological Contactor (RBC) Replacement Project involved a variety of essential construction activities aimed at upgrading the wastewater treatment facility. The project included the demolition of portions of the existing RBC units and basins, which were replaced to enhance the treatment process. In place of the existing systems, new Moving Bed Biofilm Reactor (MBBR) aeration basins were constructed to improve biological treatment efficiency.

A new Blower Building was constructed to house the equipment necessary for air delivery, while blowers and a coarse-bubble aeration system were installed to support the aeration process within the basins. The project also included the installation of air piping connections to ensure proper air distribution throughout the treatment system, as well as process water piping to facilitate the flow of treated water throughout the plant.

In addition, the electrical systems for the new components were fully integrated to ensure reliable equipment operation, and an advanced Instrumentation and Control system was installed to effectively monitor and manage the treatment process. Supporting site and utility work was also completed to ensure the successful installation and operation of all new systems. These improvements enhance treatment efficiency, increase system reliability, and support the facility's long-term operational needs.
