Graton.Occidental County Sanitation District - Graton Sewer Transfer Pipeline
Occidental County Sanitation District (OCSD) and Graton Community Services District (Graton) both have sewer service charges which are among the highest rates in California.
The high rates are due to the cost associated with operating a small wastewater systems in areas with stringent wastewater treatment requirements. OCSD is currently hauling wastewater from an Occidental lift station to the Airport/Larkfield/Wikiup Sanitation Zone (ALWSZ) treatment plant for treatment and disposal in north Santa Rosa.
In 2021 OCSD and Graton agreed to conduct a feasibility study to assess transporting untreated wastewater from OCSD to Graton for treatment and disposal, to assess the capacity of the Graton wastewater treatment plant to treat and dispose of the total combined flow, and to construct a pipeline from OCSD to Graton to reduce costs and provide Graton with additional income necessary to prevent significant rate increases in the near future.
