Santa Ana 2020 Urban Water Management Plan <br />arcadis.com <br />6-38 <br />6.10.1.1 Operational Control and Reporting Period <br />As described throughout the report, the City is a retail agency that relies on groundwater and imported <br />water. <br />Water supply energy intensity was calculated for the CY 2019. This is a standard for energy and GHG <br />reporting to the Climate Registry, California Air Resources Board and the United States Environmental <br />Protection Agency. Calendar year reporting provides consistency when assessing direct and indirect <br />energy consumption within a larger geographical context, as fiscal year starting dates can vary between <br />utilities and organizations. <br />6.10.1.2 Volume of Water Entering Processes <br />According to the City water audits, the City extracted 25,504 AF of groundwater from the OC Basin and <br />distributed 31,785 AF of both groundwater and imported water. Water volume is based on metered data. <br />6.10.1.3 Energy Consumption and Generation <br />According to Southern California Edison Electricity Bills, groundwater wells consumed 7,142,733 kilowatt <br />hours (kWh) of electricity and booster pumps and MET Connections along the distribution system <br />consumed 8,650,011 kWh of electricity. Currently, the City does not generate renewable energy. In the <br />process of writing this report, the City discovered that the consumption amounts on SCE meters did not <br />match the consumption amounts listed in SCE bills. The City is in the process of establishing why the <br />meters and bills do not match but for this report, the Energy Consumption listed in the tables reflects the <br />consumption noted in SCE bills that the City receives. <br />6.10.2 Wastewater and Recycled Water Energy Intensity <br />In CY 2019, the City consumed 2.8 KWh per AF for wastewater services (Table 6-10). The basis for <br />calculations is provided in more detail in the following subsections.
