Executive Summary:
State of California (State) Department of General Services (State General Services) and Sonoma Valley County Sanitation District (District) desire to reduce the amount of storm water and inflow and infiltration into District’s collection system and treatment plant from Sonoma Developmental Center (Center). District will accomplish this by addressing issues with downspouts, sump pumps, roof drains, sewer mainlines, and manholes that contribute to inflow and infiltration. In addition, sewer cleanouts for buildings that were demolished as a result of the Sonoma Complex Fires will be capped to eliminate surface runoff from entering the District’s collection system. State General Services will pay District up to $300,000, over the next three years (up to $100,000 per year), under the proposed agreement to complete this work.
Discussion:
The Center is owned by State and managed by State General Services. During storm events, District’s collection system is subject to sanitary sewer overflows by increased inflow and infiltration from various sources. As part of collection system maintenance and inspection, District endeavors to identify sources of inflow and infiltration in order to reduce sewer overflows.
During summer 2019, District was granted access to Center’s property for the purpose of assessing Center’s collection system. As a result of this assessment, Center was identified as a source of inflow and infiltration to District’s collection system. Additionally, the assessment identified building downspouts and basement sump pumps that are connected to District’s collection system rather than diverted to the storm drain system.
State General Services and District desire to reduce the amount of storm water and inflow and infiltration into District’s collection system and treatment plant.
Sonoma County Water Agency (Sonoma Water) operates and manages District under contract with District.
WORK UNDER THIS AGREEMENT
Under the proposed agreement, District will perform work to address issues with downspouts, sump pumps, roof drains, sewer mainlines, and manholes that are either connected to District’s collection system or contribute to inflow and infiltration. In addition, sewer cleanouts for buildings that were demolished as a result of the Sonoma Complex Fires will be capped to eliminate surface runoff from entering District’s collection system.
Under the proposed agreement, District will invoice State General Services at the same rates District allocates to its internal projects and programs up to a maximum of $300,000 (up to $100,000 per year for three years). District is recovering its actual costs with no markup. The agreement will terminate on June 30, 2022.
REQUEST FOR SONOMA WATER GENERAL MANAGER EXECUTION, AMENDMENT AND TERMINATION AUTHORITY
Staff recommends that the Board authorize Sonoma Water’s General Manager to execute an agreement to perform work to reduce storm water and inflow and infiltration through June 30, 2022, in the amount of $300,000 in a form approved by County Counsel, and, consistent with other agreements, to amend or terminate the agreement with approval of County Counsel. County Counsel and State General Services are in the process of preparing the agreement. Delegated authority is recommended in order to finalize and have the agreement executed as soon as possible to allow for work before the rainy season begins.
