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.

Shallow flooding dust mitigation
Gravel dust mitigation
Water System Priority:Regulatory Compliance
Owens Lake Dust Mitigation Project
• 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)
• 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 reliabilityOur 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
SupplyThe 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 Capture2)Water Conservation2)Water Recycling3)San Fernando Basin Groundwater Remediation
