Water System Priority:
Regulatory Compliance
Safety of the water we provide to our customers is
LADWP’s #1 Priority
Drinking Water Regulations Require Major Investment in
Water Infrastructure – two major water initiatives:
1) Open Reservoirs: cover, replace, or provide add. treatment
Regulation: Long Term 2 Surface Water Treatment Rule (LT2, April 1, 2014)
2) Chloramine Disinfection: system-wide change will reduce harmful
disinfection byproducts
Regulation: Stage 2 Disinfection By-Products Rule (DBP2, June 30, 2021)
Failure to comply with regulatory requirements is NOT an option.

Water System Priority:
Regulatory Compliance
Owens Lake Dust Mitigation Project
Gravel dust mitigation
• 90% of dust is controlled and Owens
Lake is no longer in the top 10 list of
PM10 (dust) emissions
• 42 square miles of dust control in
operation
• Over $1.2 billion spent to date in
capital (since Sep. 2000);
$72 million in annual O&M (including
cost of replacement water)
Shallow flooding dust mitigation
• Using up to 95,000 acre-feet per year
of water from Los Angeles Aqueduct

Water System Priority:
Infrastructure Reliability
LADWP’s Water System is large and complex
Continually aging (233 miles of pipe are over a century old and 70% of pipes
are more than 50 years old)
Maintenance and replacement is an ongoing and continuous effort
Water System Annual Leak Rate
15 leaks per 100-miles is below N. America
average of 25 leaks per 100-miles of pipe
Current 315-year Pipe Replacement
Cycle - severely deficient of frequency
required for continued reliability
Our 7,200 miles of water distribution pipeline is the backbone of our
delivery infrastructure – we work very hard to keep its service reliability

Water System Priority:
Sustainable Water Supply
The City of Los Angeles plans to meet all new water
demands through local resource development.
Environmental regulatory challenges and impacts of climate
change requires continued focus on four major water initiatives:
1)Stormwater Capture
2)Water Conservation
2)Water Recycling
3)San Fernando Basin Groundwater Remediation
