1 City of Los Angeles High Efficiency Plumbing Fixtures Ordinance No : Nexus Among Energy, Water & Sustainability David Wright- General Manager Nancy Sutley- Asst. General Manager of Office of Sustainability David Jacot, P.E., Director of Efficiency Solutions and Amir Tabakh P.E., Chief of Efficiency Solutions Group & La Kretz Labs Sixth Emerging Water Technology Symposium May 15-16, 2018

2 Putting Customers First: Next Century Water and Power: Why Energy Efficiency? Why Energy Efficiency for LA?

3 Total California Electricity Use = 250,494 GWH Next Century Water and Power: Water-Related Energy Use In California Water-Related Use Source: CEC, 2005 Integrated Energy Policy Report 3

4 LA s Sources of Supply Bay Delta State Water Project Castaic Power Plant Sierra Mountains LA Aqueduct Colorado River Aqueduct Local Groundwater, Stormwater, Conservation & 4 Recycling 4

5 Next Century Water and Power: Why Water Conservation and Efficiency? Drivers: Most water used in Southern California is not locally obtained Imported sources Sierra snowmelt (SWP) Colorado River (CWA) ALL imported sources are under pressure: climate, population, water quality criteria Options: Stormwater capture Recycling Conservation and efficiency 5

6 Next Century Water and Power: Energy Intensity Within Service Area A High-Resolution Assessment of Water Utility Energy Intensity, UC Davis CWEE (for LADWP), 2016 Average energy intensity values for the LADWP Service Area and per pressure zone from year 2008 to LADWP Service Area Energy Intensity Includes Treatment and Distribution, Wastewater Collection and Treatment (Outdoor and Indoor) within the Service Area Does not include energy intensity attributed to Extraction and Conveyance outside the Service Area Does not include groundwater sources Source: UC Davis CWEE,

7 Benefits of Water Conservation Cumulative water conserved from FY 2007/08 to FY 2013/14 by LADWP customers is 578,141 acre-feet. Equivalent to: Powering over 308,000 homes in L.A. for 1 year Eliminating 1.48 billion pounds of CO 2 emissions Eliminating 134,772 passenger vehicle emissions for 1 year Avoiding GHG emissions by recycling over 244,000 tons of waste instead of sending it to the landfill 7 7
