File Number: 17-263 <br />Due to the age of the aeration system, there is only one U.S. vendor that can still provide <br />replacement diffusers. Purchasing a different type of diffuser would require a capital <br />improvement project involving the design and engineering of a completely different air delivery <br />system and replacing all existing piping. In 2002, the installation of the existing system for one <br />basin cost $350,000; the anticipated cost would be much greater today. <br />The WPCP currently needs to replace diffusers in both basins. Purchasing replacement <br />diffusers for our system while they are still commercially available is the most economical <br />choice to meet immediate wastewater treatment requirements. It will also provide time to plan <br />and budget for the complete modernization of the aeration system. <br />California Public Contract Code section 3400(c)(3) permits public agencies to make sole <br />source purchases if the product is only available from one source. <br />Current Agency Policies <br />·City Council Goal: Maintain and enhance San Leandro’s infrastructure. <br />Applicable General Plan Policies <br />·Policy CSF-6.4 Wastewater Collection and Treatment.
