Current Update of the Main Plant Rehabilitation Project: Sanitary District No. 5 awarded the construction contract to low bidder, Auburn Constructors Inc (ACI) of Sacramento, CA. ACI began construction on June 11, 2012, and is expected to complete the rehabilitation project near the end of 2013.
Historic Overview: The District recently conducted a condition assessment that found the District's main wastewater treatment plant well maintained, although considerable signs of aging were apparent. Mechanical and electrical equipment is at or beyond its expected useful life and below efficient energy, environmental, and safety standards. In addition, the close proximity to the ocean and the San Francisco Bay, which is not typical for wastewater treatment plants, creates a very harsh and corrosive environment.
The current main plant was constructed in the early 1980s, with some structures dating to the 1960s. It is anticipated that routine maintenance costs will rise to significant annual expenditures. Therefore, the Board of Directors of Sanitary District No. 5 has authorized a report for the Preliminary Design of the Main Plant Capital Rehabilitation and Replacement Project to be completed in 2011. If the main plant rehabilitation project is deemed appropriate for the District's needs, construction would begin in 2012 and be completed by 2014.
In the event the District moves forward with this project, Tiburon and Belvedere residents will be informed as to its progress at regular intervals during monthly Board meetings and through the District's quarterly newsletter.
