Capital Improvement Projects

Sausalito-Marin City Sanitary District continually maintains and upgrades their wastewater system to meet stringent water quality regulatory requirements and to assure reliable wastewater conveyance and treatment for our communities protecting public health, the environment and the San Francisco Bay.  

Construction projects undertaken by the District include on-going annual maintenance and long-range capital improvements of the system.


Ten Year Infrastructure Renewal Program (CIP)

Following an extensive evaluation of the District’s operations and infrastructure, in 2010 the District adopted a comprehensive financial and 4-year sewer service rate plan to provide revenue for needed collection system, pump station, pipeline and treatment plant renewal and upgrades. The work included a 10-year capital improvement plan (CIP) through 2020/21 which identified $53 million of needed sewer infrastructure improvements.

To date, approximately $14 million of CIP improvements have been completed. Of the remaining $39 million, approximately $33 million is programmed for the treatment plant and $6 million for sewer collection projects. At the conclusion of the current 10-year capital improvement program, new expenditures on capital improvements will continue due to additional treatment requirements by changing State and Federal water quality regulations.  The financing of current projects will span over the next 20 to 30 years.

In 2013, the District completed another extensive financial and sewer rate analysis. Out of this work, the District has adopted a 5-year sewer rate plan to ensure adequate revenue is available in support of the District’s operations and 10-year CIP through completion.
