SECTION 6: POTENTIAL FOR HEAD RECOVERY AT MWD CONNECTIONS 17 <br />III„ s r A riaim SA, <br />The pressure reducing station SA-3 is installed in a vault under the sidewalk at the south east corner of Bristol <br />Street and McFadden Avenue. The configuration is shown in Figure 3, with one PRV and two isolation valves, <br />approximately eight feet below the sidewalk. The SCADA monitoring and associated electrical meter are <br />installed in small cabinets mounted nearby on the sidewalk. The SCE Service Account is 3-035-8796-80 and the <br />Rate Schedule is TOU-GS-1-A. <br />The PRV flow rate is typically controlled to 8 CFS when in use. The observed pressure drop was from 172 to 85 <br />psig, according to the installed pressure gages. <br />Figure 3 <br />WD PRV To Santa, Aria <br />Distribution <br />aUIt U,ride r S i iewaIk <br />6.5 III° "' II[;;; III "' "III III,,,, III°,III Iii:..:..:c r°r S <br />The proposed project at SA-3 is to install a new hydro -turbine generator in parallel with the existing Pressure <br />Reducing Valve. There is no room in the existing vault, so a new vault would be required side by side with the <br />existing vault. This is illustrated in Figure 4. The new vault would contain the new hydro -turbine and generator, <br />a remotely controlled valve on the inlet of the turbine and an isolation valve on the discharge, an electrical panel <br />to control the turbine and take power from it, a new metered connection to deliver the power to SCE, and some <br />additional SCADA points. <br />°Ie�W��coin�ll',9 ,(JCisoi iin �f�,�C('0u,u.m�ii�: " 26 — 77 G II�II" 112 11�.11 N <br />PREVIEW Date: Nov 03, 2021 Workspace ID: WS00800354 Funding Opportunity Number: R22AS00023 <br />
