The data used in this section comes from the City’s Utility Billing system, invoices for <br />services provided by the Wastewater Management Division, data bases with customer discharge data <br />and operating data for the City’s Water Pollution Control Plant. Customer data is used for the allocation <br />of costs, development of rates, and analysis of the impact on customer bills. <br />2.1 Residential Wastewater Charges Tax Roll Assessment Data <br />Wastewater charges for residential dwelling units (houses, apartments, condominiums and the like) for <br />the period of July 1 to and including June 30 of each fiscal year are filed with the County Auditor of the <br />County of Alameda who then enters such charges as an assessment of the tax roll against the respective <br />premises. The City provided a list of assessments of residential wastewater charges for Fiscal Year July <br />1, 2017 – June 30, 2018. The data is summarized in Appendix A, Table A-1. This data is used to project <br />the number of residential accounts. <br />2.2 EBMUD Metered Water Use Data <br />At the City’s request, EBMUD (East Bay Municipal Utility District) provided monthly water meter reading <br />data for accounts within San Leandro. The data is used to estimate the projected number of commercial <br />and institutional accounts and the amount of wastewater discharge to the sanitary sewer by the City’s <br />residential, commercial and institutional customer classes. The data provided by EBMUD is summarized <br />in tables in Appendix A: Table A-2 (number of meters), Table A-3 (monthly metered water use) and Table <br />A-4 (monthly average metered water use per meter). Table A-5 shows the estimated amount of <br />wastewater discharge to the sanitary sewer by the City’s residential, commercial and institutional <br />customer classes. <br />The City’s residential customer class has two categories: single family and multiple family.1 Because <br />EBMUD and the City define the multiple family customer class differently is was not possible to calculate <br />precisely the average wastewater discharge per multiple family billing unit. Estimates of the average <br />number of multiple family billing units in the tax roll assessment data and multiple family accounts in the <br />EBMUD data were developed and support the current rate structure estimate of the percent difference <br />between average single family wastewater discharge and average multiple family billing unit wastewater <br />discharge. The current rate structure uses an average multiple family billing unit wastewater discharge <br />difference that is 16 percent less than that for single family customers. <br />2.3 Industrial Wastewater Discharge Data <br />The City monitors and analyzes the wastewater discharge for 20 Industrial User customers. The <br />wastewater discharge monitoring and analysis data is summarized in Appendix A, Table A-6. This data is <br />used to project the wastewater discharge of Industrial User accounts. <br /> <br />1 Note that the EBMUD multiple family category is defined differently than the City’s multiple family category. The EBMUD <br />multiple family category is split into accounts with 5+ units (Apartments) and accounts with 2, 3 or four units. Section <br />12.5.100(m) of the San Leandro Administrative Code defines multiple family as “Any residential unit designed to house one <br />family in a building containing more than two such units, including triplexes, quadplexes, and apartments. For the purpose of <br />this Code, mobile homes located in a mobile home park shall be considered multiple-family dwellings.” <br />97
