Strategic Plan <br />Advantages and disadvantages of switching to the Oro Loma plant for treatment are given <br />in Table 6-2. <br />TABLE `6-2.

Currently the plant influent flows average about 63 mgd and <br />have been increasing at only about 1% per year. EBMUD feel that there is plenty of excess <br />capacity and that they could easily accept the City of San Leandro flows. <br />A forcemain and lift station would also be required to transfer flows from San Leandro to <br />EBN=. EBMUD staff has analyzed their existing sewer system and has determined that <br />the 51-inch or 63-inch portion of the EBMLJD South Interceptor could be utilized to deliver <br />raw sewage from San Leandro to the EBMUD plant. Three miles of pipeline are still <br />required to convey sewage from San Leandro to the 51-inch portion of the interceptor. In <br />addition, it will be necessary to equalize peak storm inflows at the San Leandro WWTP site <br />in order to reduce the peak flow to 12 mgd, which can be handled in the existing EBMUD <br />sewer system. The location of the possible new forcemain is shown in Figure 6-2. The costs <br />for the lift station, forcemain, and other facilities are given in Table 6-3. <br />00142.001 6-3 <br />� 114 <br />
