September 26, 2013
LA’s Water Reliability 2025
One Water Leadership Summit

2. LADWP’s Long, Rich and Proactive Water
History Helped Transform the City of LA

3. LA’s Reliance on MWD Water Has Increased
7-Fold in the Past 30 Years

4. Using Less Water Than 40 Years Ago Despite
Population Increase of 1 Million

5. New Challenges Require Continued Proactive
Planning by LADWP
Local Groundwater Contamination
& Basin Urbanization
Threats to Imported Water
-Environmental
-Competing Demands
-Climate Change
Rising MWD Water Costs

6. LA’s Water Reliability 2025 is Combination of
Two Important LADWP Initiatives
+ =
SFB Groundwater
Remediation Program
Ensuring safe drinking water
that meets all regulations
Local Water Supply

7. Centralized Stormwater Capture Projects

8. Distributed Stormwater Capture Projects
Elmer Avenue Retrofit
Before After
Cistern
Rain Barrel
Rain Garden

9. Stormwater Capture Master Plan
• Evaluate existing stormwater
capture facilities and projects
• Quantify maximum
stormwater capture potential
• Provide potential strategies to
increase stormwater capture
• Recommend stormwater
capture projects, programs,
policies, and incentives
• Determine the economic mix
of centralized vs distributed
stormwater capture projects
