    View Meeting Agenda

    The Occidental County Sanitation District Sewer Wastewater Compliance Transport Project would allow Occidental’s wastewater to 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.

    All modifications are needed in the Project in order 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. The deadline for public comments has been extended to 5 p.m., February 24, 2017. In addition, a public hearing will be held on February 16, at 6 p.m. at the Monte Rio Community Center. Comments made at the Public Hearing will be recorded.

    Past Recycled Water Projects

    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. To learn more about the District and the proposed project, please see the following documents:

    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.
