Memorandum

To: The Honorable Lake County Board of Supervisors
From: Robin Borre, Special Districts Administrator
Subject: (Sitting as the Lake County Sanitation District, Board of Directors) Consideration of Agreement between the County of Lake on behalf of Lake County Sanitation District (LACOSAN), and Jacobs Engineering Group Inc. for LACOSAN Full Circle Effluent Pipeline Project Update to the 2004 Preliminary Design Report for an Amount not to Exceed Three Hundred Twenty Thousand Six Hundred Eleven Dollars and No Cents ($320,611.00) and Authorize the Chair to Sign
Executive Summary: The LACOSAN Full Circle Effluent Pipeline Project, Update to the 2004 Preliminary Design Report (PDR) will update the PDR that was prepared for the full circle project in 2004. Lake County has a long history of beneficial wastewater recycling and reuse. In 1997 the first phase of a project between the Lake County Sanitation District (LACOSAN), Northern California Power Agency (NCPA), and Calpine Corporation saw the completion of a treated effluent pipeline between the Southeast Regional Wastewater Treatment Plant, the Middletown Treatment Plant and the two geothermal power producing partners operating in a known geothermal resource area referred to as the Geysers. This first phase was followed closely by a second phase of construction which gathered treated effluent from the Northwest Regional Wastewater Treatment Plant and the Clearlake Oaks County Waterworks District Treatment Plant and conveyed it to the SETP and ultimately on to the Geysers. This project known as the Basin 2000 project collected treated effluent from ten communities along the northern and eastern shores of Clear Lake and transported it to the Geysers for injection into the steam fields.
In 2004 a Preliminary Design Report was completed for a project which would provide the same collection of treated effluent from wastewater treatment plants located on the western and southern shores of Clear Lake. This work has been given the name “Full Circle” because it continues and completes the reuse of treated wastewater from wastewater treatment plants encircling Clear Lake. The goal of the Full Circle Effluent Pipeline is to convey treated wastewater from existing wastewater treatment plants (WWTPs) at Lakeport and Kelseyville around the south side of Clear Lake to inject this into the stream fields.
There is renewed interest in the Full Circle project and preliminary discussions with the multiple partners previously involved indicate support for the project. There is a need to review and revise the former Preliminary Design Report, which was completed in November 2004 to account for changes. New technologies have emerged, new pipeline alignments may need to be considered as the highway has shifted, and new partners may want to participate in the potential for beneficial reuse of the treated effluent.
The project has a seventy-five percent federal cost share authorized by the Congressionally Directed Spending (CDS) / Community Project Funding (CPF) (Community Grants) Water Infrastructure Project Pursuant to the FY2022 Consolidated Appropriations Act (P. L. 117-103), to capitalize LACOSAN’s funding to support the planning and design of water improvement projects and activities to protect human health; through a grant agreement with the United States Environmental Protection Agency (U.S. EPA). A Request for Proposals (RFP No. 24-21) was published in the local record-bee and submitted by the Lake County Purchasing Agent through a government website platform CivicPlus for nearly (60) days, and we received one (1) proposal, Jacobs Engineering, Inc. of Redding, CA. A Consultant Selection Board (CSB) was convened in accordance with County policy and the recommendation of the CSB was to begin negotiations with the one firm that submitted a proposal, Jacobs. Negotiations were completed and an agreeable scope and price have been identified and incorporated into the proposed agreement for services. Attached for your consideration is an agreement for the Engineering and Design Services for the project.
