Occidental County Sanitation District

    Occidental County Sanitation District to Airport-Larkfield-Wikiup Sanitation Zone Wastewater Transport Project

    In December 2017, the Board of Directors of the Sonoma County Water Agency (Water Agency), which operates the Occidental County Sanitation District’s (District) Wastewater Treatment Facility, approved a project for transporting untreated wastewater from the OCSD to the Airport-Larkfield-Wikiup Sanitation Zone (ALWSZ) for treatment, storage, and reuse to avoid future discharges into Dutch Bill Creek and potential violations of the District’s operating permit.

    The Project, which is currently under construction, will allow the Occidental County Sanitation District (District) to comply with conditions set forth by the North Coast Regional Water Quality Control Board in Order No. R1-2012-0101 (Order). This order requires the OCSD to cease discharging secondary treated recycled water to Dutch Bill Creek by January 31, 2018. The Project includes transporting untreated wastewater to the ALWSZ wastewater treatment facility for treatment, storage, and disposal. The ALWSZ wastewater treatment facility currently treats wastewater to secondary and tertiary standards and utilizes irrigation of agricultural lands for disposal of secondary and tertiary-treated recycled water.

     

    Past Project Proposals (These proposals are no longer being considered)

    Occidental County Sanitation District Sewer Wastewater Compliance Transport Project

    The Occidental County Sanitation District Sewer Wastewater Compliance Transport Project proposed Occidental’s wastewater be transported, treated and discharged at treatment plants near Guerneville and Airport Business Park by making minor modifications to the District's wastewater treatment facility on Lu Dan Road, lift station on Bohemian Highway, and the Russian River County Sanitation District's main lift station and an adjacent parcel of land.

    The Project was needed to bring the District into compliance with the North Coast Regional Water Quality Control Board's law to protect the habitat for endangered coho salmon that live in the watershed where recycled water is discharged.

    A Draft Initial Study/Negative Declaration (IS/ND), in compliance with the California Environmental Quality Act, was released on December 21.  A public hearing was held on February 16, at 6 p.m. at the Monte Rio Community Center. Comments made at the Public Hearing were recorded.

    Occidental Wastewater Treatment Facility Recycled Water Project

    The Occidental County Sanitation District conducted a study for the Occidental Wastewater Treatment Facility Recycled Water Project to upgrade the treatment plant and change how the recycled water is managed. The Initial Study is a preliminary analysis of the project’s potential environmental impacts, and is used to determine whether a Negative Declaration or an Environmental Impact Report will be prepared. The Project proposes beneficially re-using recycled water for agricultural irrigation on farms near the District. California has among the strictest laws on recycled water in the United States. Disinfected tertiary treated recycled water can be used for everything except drinking. Learn more about recycled water.

    Public Meetings

    The Occidental County Sanitation District’s (District) regularly holds community meetings to inform, educate and seek input from ratepayers and surrounding residents on possible solutions for treating, storing, and disposing of wastewater generated in Occidental. The District currently discharges recycled water into a pond located at the headwaters of Dutch Bill Creek during the summer and to Dutch Bill Creek during the winter. The District is required by the North Coast Regional Water Quality Control Board to stop releasing recycled water into the pond. The District is currently examining feasible projects that meet the unique requirements of Occidental.
