Capital Improvement Projects

Studies that are underway and projects that are in the planning/preliminary design stage include the following:

2016:

Digester Inspection and Cleaning

The District is in the planning phase for cleaning and inspecting two digester tanks. Digesters are large holding tanks that heat and circulate sludge (organic solids found in the sewer system) to produce gas and reduce the volume of solids that need to be processed and delivered to landfill. The gas produced is used to heat the digesters without the need for electricity or fossil fuels. The digesters are scheduled to be cleaned every ten (10) years and are currently due. While the tanks are empty an inspection will also be performed to evaluate if seismic reinforcement and/or repairs are needed.

2014:

Treatment and Wet Weather Flow Upgrade Project

The SMCSD Treatment Plant Upgrade Project would implement improvements to the existing treatment operations, including the addition of a headworks, new primary clarifier, secondary upgrades, tertiary polishing, and equalization storage. The project has been developed to address regulatory compliance, plant operation, reliability, performance, and to allow the plant to fully process all flows, even during storms that can fill the sewers with stormwater.

The District has awarded a final design contract for $2.1 million, and design is about 100% complete. The project construction cost is currently estimated at $21 million. The District is currently evaluating firms for a construction management services contract. The final design should be complete by the fall of 2015, followed by bidding, award and construction. The construction phase is estimated to last 16 to 24 months.

The project’s environmental assessment/Initial Study document (EA/IS) is complete. The District has approved the required mitigation and monitoring plan for the state environmental assessment (CEQA). The District is now waiting for approval for the federal environmental assessment (NEPA). Federal approval is necessary because the District treatment facility is located within the National Park Service, Golden Gate National Recreation Area.

The San Francisco Bay Conservation and Development Commission (BCDC) permit No. 1908.024.09 (amendment No. 9) has been issued for the project. The District has submitted to BCDC the required project public signage plan for review and approval. The State Land Commission (SLC) has made a determination the project is not within their jurisdiction and does not require a permit from the SLC.

The District is preparing a new application for project funding under the Clean Water State Revolving Fund Program since the program requirements were changed in 2014.

2014:

Scotties (wet weather) and Whiskey Springs Pump Station Replacement

The District has awarded a contract for $135,000 to start the study and preliminary design phase to replace the Highway Booster sewer pump station and the Scotties wet weather pump station. In partnership with the City of Sausalito, the work includes evaluation of a combined Whiskey Springs (City-owned) sewer and Scotties (District-owned) wet weather pump station. The Final design and construction will follow completion of the pre-design phase.

Treatment Plant Upgrade Project Environmental Study

BACKGROUND:

The Sausalito-Marin City Sanitary District (SMCSD), in coordination with the National Park Service (NPS), is starting the planning process to upgrade the SMCSD’s wastewater treatment facility at Fort Baker, in Golden Gate National Recreation Area (GGNRA). Recently, federal and state regulators instructed the SMCSD to upgrade its facility in response to state and federal water quality requirements. This project would upgrade the wastewater treatment facility, thereby improving the quality of water discharges and improving SMCSD’s ability to prevent sanitary sewage spills into the San Francisco Bay.

THE PROJECT INCLUDES THE FOLLOWING IMPROVEMENTS:

  • Improve Primary Treatment with Addition of Headwords to remove grit and other debris before the effluent is treated by additional processes.
  • Increased secondary treatment capacity refurbishing the treatment towers/pumps to improve treatment when sewage flows are high during rainstorms.
  • Upgraded tertiary treatment systemto increase capacity of the effluent sand filters, thereby ensuring improved water quality discharging into the Bay.
  • Convert an existing on-site residence to meet office space requirementsand to comply with the Americans with Disabilities Act (ADA) without any new construction. - Completed.
