Transportation Planning for Southeast Plant Biosolids Digester Facilities Project

San Francisco, CA

Southeast Plant Biosolids Digester Facilities Project is one of the largest and most complex projects in the San Francisco Public Utilities Commission’s Sewer System Improvement Program (SSIP). The objective of this project is to fully replace the existing aged and failing facility with new biosolids digester facilities that reliably meet the SSIP goals and Levels of Service and provide continued compliance with present and anticipated future regulations. The project minimizes plant impacts to the neighborhood with respect to aesthetics, odors, noise and traffic, and is a positive enhancement to the local community. New biosolids handling treatment processes include solids thickening, anaerobic digestion, gas handling, energy generation/recovery, dewatering, odor control, control systems and related ancillary processes. The new facility will be designed to promote energy recovery, onsite/offsite use for sustainability, and economic and environmental benefits.

Cordoba Corp is part of the Brown and Caldwell team selected to provide planning and preliminary engineering detailed design, and procurement and engineering construction support for the Biosolids Digester Facilities Project. The overall scope of work included providing specialized expertise, detailed design, contract management, pre-construction services, construction support, land needs and property acquisitions, training and technology transfer, and communication, public outreach, traffic analysis and CAD services.
