2. 2015 Urban Water Management Plan (UWMP)
Current Challenges
Historic drought in California
An extended 16-year drought on the Colorado River watershed
Low groundwater and local reservoir levels throughout Southern California due to dry hydrology
Reduction in SWP deliveries due to the restrictions in place to protect endangered Delta smelt and salmon
Drought and environmental mitigation impacting the supply available from the Los Angeles Aqueduct
Mandated conservation under SWRCB emergency regulation
UWMP Provides a Look Ahead at EMWD Reliability
Covers a 25 year planning horizon
Evaluates supplies available to determine if they are adequate to meet existing and future demands under specified conditions
Reports progress on Water Conservation Act of 2009 (SBX7-7)

3. Components of UWMP Introduction and Overview - Why we need UWMPs
Plan Preparation - Coordination and Outreach
System Description - Overview of EMWD, facilities, climate and Population
System Water Use – Sources and uses of water
Baselines and Targets – SBx7-7 (“20 x 2020”) calculations
System Supplies - Overview of existing and proposed projects
Water Supply Reliability - Is supply reliable?
Water Shortage Contingency Planning - Overview of Water Shortage Contingency Plan Stages
Demand Management Measures - Conservation
Plan Adoption, Submittal and Implementation – Dates for adoption and submittal

4. Reduction in imported deliveries due to State Drought Regulations
Recent Supply Sources
Water Received by Source (AF)
Reduction in imported deliveries due to State Drought Regulations
Focus on local supplies
Imported water reduced due to mandatory restrictions
MWD allocation less than a 5% reduction

5. 2015 Retail Potable/Raw Water Use Distribution

6. 2015 Retail Recycled Water Use Distribution

7. Population Growth and Future Projections
EMWD is only 40% built out an has room to grow.
Population projection based on 2015 Empire Economic Absorption Study (using DOPP data)

8. Projected Retail Demands (2020 – 2040)

9. Projected Retail Supplies (2020 – 2040)

10. Projected Wholesale Demands (2020 – 2040)
Includes direct and recharge deliveries

11. Projected Wholesale Supplies (2020 – 2040)

12. Water Conservation - Progress Towards SBX7-7 Target
EMWD’s retail demands were at 130 GPCD in 2015, a 34% reduction from the baseline average
Target calculated using Method 2 (Water Use Efficiency Standards)

13. Continued Investments in Local Supplies
Recycled Water
Full utilization of recycled water
Increases from approximately 45,000 AF annually to over 53,000 AF annually
Brackish Water Desalination
Provides a potable water supply from an otherwise unusable source
Protects basin groundwater quality
Future expansion (Perris II Desalter)
Potable Groundwater
Moreno Valley
North Perris

14. MWD’s 2015 UWMP Key Findings
Meet challenges with proactive planning
Integrated Resources Plan
Water Surplus and Drought Management Plan
Water Supply Allocation Plan
MWD supply planning includes development of diverse portfolio
Investments in local resources
Conservation
Proactive management of Colorado River and State Water Project resources
Supply is sufficient to meet member agency demands (2020 – 2040)
