Bodega Bay Wastewater Treatment Plan Bodega Bay Public Utility District, California Coastland | DCCM provided engineering design services for the addition of a second cloth filter at Bodega Bay’s wastewater treatment plant. The additional filter gives District staff the flexibility to alternate filter units during the lower flow months, as well as use both filters during high flow months. The second filter eliminates a critical flow limitation through the plant and allows the WWTP to operate in conformance with State regulations. Construction plans and specifications were completed to incorporate the new filter into the overall WWTP system. The work included piping, electrical and SCADA integration into the existing control system. Coastland | DCCM also provided construction management and inspection services on the installation of the second cloth filter.
