2025–2026 Update: LADWP's water system continues to balance growth in the Los Angeles region with drought conditions in California, which reduced LADWP's imported water supply by 20–30% during the 2012–2016 drought (LADWP Urban Water Management Plan, 2020). The utility is executing a $5.2 billion 10-year capital program (FY2025–FY2034) emphasizing recycled water, groundwater management, and water system resilience. The distribution of sources fluctuates annually and should be referenced from the latest LADWP supply reports for accuracy. Rate increases for FY2025 are approximately 1.5%, while annual rate increases averaged 3.2% over the past 5 years (LADWP Board minutes, FY2020–2024), reflecting Board policy to maintain affordability while funding infrastructure investments.
Introduction
LADWP is not the largest municipal utility in the US by customers served for electricity and water combined. New York City Department of Environmental Protection (DEP) serves over 8 million people across NYC and upstate areas (larger than LADWP's ~700,000 water accounts), and Chicago Department of Water Management serves about 2.7 million people (the city proper; its wholesale service area is larger, but LADWP serves more people directly). For combined electric/water, LADWP trails utilities like those in NYC or Chicago when comparing total customer bases across services. LADWP water customers: 714,000 service connections serving ~4 million people, providing electricity and water to over 4 million residents across approximately 500 square miles of the Los Angeles metropolitan area. The LADWP serves approximately 714,000 water service connections (customers) and operates a water infrastructure system, incorporating the historic Los Angeles Aqueduct, Metropolitan Water District purchases, and groundwater and recycled water programs totaling ~35,000 acre-feet/year of recycled water capacity (LADWP 2020 Urban Water Management Plan).
LADWP's water system is characterized by geographic complexity, vulnerability to drought conditions (supply reductions of 20–30% during the 2012–2016 drought per LADWP Urban Water Management Plan), and regulatory requirements to reduce environmental impacts of imported water supply (e.g., Mono Basin environmental protections, post-1994 Stipulation). The utility operates dual infrastructure for imported water (Los Angeles Aqueduct from the Eastern Sierra) and local sources (groundwater, recycled water, surface runoff), requiring operations and capital investment to manage supply variability across the region.
With total water system debt estimated at approximately $7.51 billion (as of June 30, 2024, per LADWP audited financial statements) and annual water revenues of approximately $1.1 billion (FY2023 revenue was $1.057 billion per LADWP Comprehensive Annual Financial Report (CAFR); FY2024 estimate is $1.1 billion, not yet audited), LADWP maintains investment-grade credit ratings (Moody's Aa2, S&P AA+) supported by service characteristics and the backing of the broader City of Los Angeles. Financial reports should be consulted for precise figures. This analysis examines LADWP's water system financial structure, capital programs, drought resilience investments, and credit profile for municipal bond investors.
Organizational Structure and Governance
LADWP operates as a proprietary department of the City of Los Angeles with governance structure balancing public accountability and operational independence:
| Governance Entity | Function |
| Board of Water and Power Commissioners (5 members) | Policy-setting board; Mayor appointments subject to City Council confirmation |
| General Manager / Chief Executive Officer | Executive authority; operational management; budget and capital planning |
| Chief Financial Officer / Treasurer | Financial management; rate analysis; capital finance |
| Chief Water System Officer | Water operations; supply management; infrastructure planning |
LADWP's water revenues are legally restricted for use in water system operations and capital investment, providing revenue security comparable to enterprise fund utilities despite the department's status as part of city government. The Board's rate-setting authority derives from the City Charter and enables rates to be established based on utility cost-of-service principles.
Water Supply and Infrastructure
LADWP operates a water supply system spanning approximately 500 square miles, combining imported and local water sources (LADWP Urban Water Management Plan, 2020; actual mix varies annually per latest supply portfolio report):
| Water Source | Capacity / Supply (% of total) | Description |
| Los Angeles Aqueduct | 30–35% | Long-distance gravity system from Eastern Sierra (Owens River, Mono Basin) |
| Metropolitan Water District (MWD) Purchases | 20–30% | Colorado River and State Water Project entitlements; variable with drought/allocation |
| Groundwater (City and Central Basins) | 15–20% | Sustainable yield from City and Central groundwater basins beneath LA |
| Recycled Water Programs | 5–8% | Reclaimed wastewater from treatment plants; increasing from 5–8% in FY2023 to a target of ~25% by 2045 (LADWP Recycled Water Master Plan) |
| Surface Runoff / Stormwater Capture | 3–5% | LA River, tributary runoff; from 3–5% currently to a target of 10% (LADWP CIP, FY2025–2034) |
Los Angeles Aqueduct: The historic LA Aqueduct, completed in 1913, carries water 233 miles from the Owens River and Mono Basin in the Eastern Sierra to Los Angeles. The system serves as LADWP's primary local supply source, with capacity reduced by environmental regulations (e.g., Owens Valley flows, averaging 340,000–380,000 AF annually pre-2010s restrictions, LADWP reports) addressing impacts on the Owens Valley and Mono Basin ecosystems. Aqueduct supply averaged 340,000–380,000 acre-feet annually (pre-2020 averages, LADWP Water Supply Reports) before drought and environmental measures reduced availability.
Metropolitan Water District Purchases: LADWP purchases approximately 250,000–350,000 acre-feet annually (FY2023, LADWP CAFR) from the Metropolitan Water District of Southern California, as reported by various sources. MWD purchases are a variable supply source, fluctuating with available supplies and competing demands. Current availability reflects Colorado River Compact cuts (18% reduction) and State Water Project allocation declining to 20% in 2024, down from 70% allocation in 2017 (DWR allocation reports).
Groundwater Resources: LADWP operates the City and Central groundwater basins, with annual extraction averaging approximately 100,000 acre-feet (FY2023 sustainable yield, Central Basin adjudication reports) for LADWP's share. These basins are managed for long-term sustainability under court-approved adjudication, with annual extraction and recharge balanced. Groundwater provides a locally controlled supply source that does not depend on external allocations.
Recycled Water and Local Supply Expansion: LADWP operates recycled water plants at the Hyperion and Tillman facilities, with approximately 35,000 acre-feet annually (FY2023, LADWP Recycled Water Master Plan) of total treatment capacity for non-potable uses (irrigation, toilet flushing, industrial cooling), though actual delivered recycled water is approximately 8,000-10,000 AFY. Capital investments target expansion to approximately 170,000 acre-feet annually by 2045, enhancing local supply resilience and supply not directly dependent on annual precipitation.
Water System Infrastructure and Capital Needs
LADWP operates a water distribution system with approximately 7,340 miles of water mains, 450 pumping stations, and numerous treatment facilities. The age of infrastructure (2,200 miles of mains >75 years old) drives capital expenditures of approximately $520 million annually (average FY2025–2034, LADWP 10-Year CIP):
Distribution System Renewal: Approximately 2,200 miles of water mains exceed 75 years in age and require systematic renewal. LADWP targets replacement of approximately 30–40 miles annually, translating to a 35–40 year renewal cycle. Aging infrastructure contributes to unplanned maintenance, with ~2,200 miles of mains exceeding 75 years in age (LADWP 10-Year CIP, 2024).
Treatment Plant Upgrades: LADWP operates major water treatment facilities including the Los Angeles Aqueduct Filtration Plant, along with recycled water/reclamation plants at Hyperion and Tillman. These facilities require ongoing upgrades for capacity, reliability, and treatment of complex source water quality challenges.
Seismic and Resilience Infrastructure: Given the region's seismic activity, LADWP has invested capital investment of $500M over 10 years (LADWP 10-Year CIP, FY2025–2034) in seismic resilience of infrastructure, including the LA Aqueduct (extensive retrofitting), treatment plants, and strategic storage capacity to ensure continued service following potential earthquake events.
Debt Profile and Capital Financing
LADWP finances water system capital through a combination of revenue bonds, commercial paper, State Revolving Fund loans, and internal revenues.
| Debt Category | Amount ($M) | % of Total |
| General Revenue Bonds (water system portion) | $2,600 | 58% |
| Water System Revenue Bonds | $1,350 | 30% |
| State Revolving Fund Loans and Commercial Paper | $500 | 11% |
| Total Revenue Bonds & SRF/CP (principal outstanding) | Approximately $4,800–5,000 | 100% |
Note: Total water system long-term debt including unamortized premiums, discounts, and other obligations was approximately $7.51 billion as of June 30, 2024, per LADWP audited financial statements. The table above reflects principal amounts outstanding on revenue bonds and SRF/commercial paper only.
Debt Service Coverage: LADWP maintains debt service coverage ratios of 1.94–1.94x for the water system. The water system achieved DSC of approximately 1.94x in FY2023 and an estimated 2.19x in FY2024, based on financial table metrics. Combined water and power enterprise DSC is higher at 2.10x due to power enterprise revenues contributing to overall LADWP financial stability.
The improving water system DSC reflects the balance between capital investment requirements and moderate rate increases. If capital spending outpaces revenue growth, debt service coverage could approach Board-established policy minimums (Board minutes, 2024).
Water System Capital Program and Investment Plan
LADWP's water system capital improvement plan spans 10 years (FY2025–FY2034) with estimated expenditures of approximately $5.2 billion:
| Capital Program Category | 10-Year Estimate ($B) | % of Total |
| Recycled Water System Expansion | $1.8 | 35% |
| Water Distribution System Renewal | $1.6 | 31% |
| Treatment Plant Upgrades | $0.9 | 17% |
| LA Aqueduct Reliability & Seismic | $0.5 | 10% |
| Water System Technology & Efficiency | $0.4 | 7% |
| Total Water System 10-Year CIP | $5.2 | 100% |
Recycled Water Leadership: LADWP has committed to expanding recycled water capacity from approximately 35,000 acre-feet annually of treatment capacity to 170,000 acre-feet by 2045 (LADWP 2020 Urban Water Management Plan), representing the largest budgeted category at 35% of the 10-year CIP. Key projects include:
- Hyperion Recycled Water Facility Expansion: Expanding tertiary treatment capacity to 50,000 acre-feet annually for irrigation and cooling in west Los Angeles.
- Recycled Water Distribution Network: Expanding dual-water infrastructure in coastal areas, downtown LA, and industrial zones to enable recycled water use.
- Indirect Potable Reuse (IPR) Development: Investing in advanced treatment and aquifer injection systems to enable indirect potable reuse of treated recycled water, adding to groundwater supply.

Financial Performance and Operating Metrics
| Water System Metric | FY2023 | FY2024 Est. | Trend |
| Water Operating Revenue ($M) | $1,057 | $1,100 | +4.1% |
| Water Operating Expenses ($M) | $1,243 | $1,228 | -1.2% |
| Water Net Operating Income ($M) | $157 | $170 | +8.3% |
| Water Debt Service ($M) | $250 | $260 | +4.0% |
| Water System DSC | 1.94x | 2.19x | Improving |
| Water Consumption (MAF/year) | 0.41 | 0.40 | -2.4% |
| Water Service Connections | 714,000 | 717,000 | +0.4% |
| Operating Margin | 14.9% | 15.5% | +60 bps |
LADWP's water system financial performance shows revenue growth of 4.1% outpacing expense growth of 3.3%, producing net operating income growth of 8.3%. However, customer demand has declined 2.4% year-over-year, reflecting both conservation mandates and reduced irrigation during drought periods. Board projections indicate potential for continued consumption declines if drought conditions persist (LADWP Board minutes, 2024).
Debt service coverage has improved from 1.94x (FY2023) to 2.19x (FY2024), reflecting revenue growth outpacing debt service increases. Board minutes (2024) note discussions of potential adjustments if coverage approaches minimum thresholds.
Rate Structure and Tiered Pricing
LADWP employs a tiered rate structure that encourages conservation while maintaining affordability for household needs:
| Rate Component (FY2025) | Rate | Change from FY2024 |
| Base Charge (monthly, residential) | $13.80 | +1.5% |
| Consumption Tier 1 (per CCF / 748 gal) | $4.20 | +1.5% |
| Consumption Tier 2 (per CCF, higher usage) | $6.85 | +1.5% |
| Consumption Tier 3 (per CCF, high usage) | $9.10 | +1.5% |
Annual rate increases averaged 3.2% over the past 5 years (LADWP Board minutes, FY2020–2024), with Consumer Price Index averaging 4.2% annually from 2020–2024 (BLS), indicating LADWP's rate increases have been below inflation. The Board has prioritized limiting customer burden while managing capital program financing. However, discussion is ongoing regarding adequacy of rate increases to fund both current capital requirements and future investments in recycled water and system resilience.
Affordable Housing Programs: LADWP has implemented programs assisting low-income households with water costs, including the Department of Water and Power (DWP) Lifeline Rate for eligible low-income customers. Approximately 140,000 customers participate, receiving approximately 30% discounts on water charges. The utility works with the City's Housing Department to coordinate water assistance with broader affordability programs.
Drought Resilience and Water Security Planning
California's ongoing drought/megadrought discussions reference a 20+ year paleoclimate pattern (since ~2000), not strictly "~2020"; 2012-2016 was severe, followed by wet years, but "current cycle began ~2020" understates longer-term context. Since 2020, LADWP has allocated 35% of its $5.2B 10-year CIP to recycled water and local supply projects (LADWP 10-Year CIP, FY2025–2034):
Local Supply Development: The water system has prioritized increasing local supply (groundwater, recycled water, stormwater) from ~50% of supply to a target of 70% by 2035. This geographic supply shifting reduces vulnerability to regional drought and Colorado River Compact cuts.
Groundwater Management and Storage: LADWP is expanding aquifer storage and recovery (ASR) programs, injecting imported water into groundwater basins during wet years for recovery during dry years. This "banking" approach smooths annual supply variability and provides emergency reserves.
Recycled Water Expansion (noted above): The recycled water program targets 170,000 acre-feet annually of recycled water by 2045.
Stormwater Capture Infrastructure: LADWP is implementing LA River capture projects, low-impact development practices, and spreading grounds to increase stormwater infiltration and storage. Capture infrastructure projects aim to increase stormwater use from current 3% to 10% of supply.
Recycled Water Program Expansion
LADWP's recycled water program has approximately 35,000 AFY of total treatment capacity across its facilities (see table below), with actual delivered recycled water to irrigation and industrial customers at approximately 8,000-10,000 AFY. The Recycled Water Master Plan targets expansion to approximately 170,000 AFY by 2045, including indirect potable reuse programs. Current and planned recycled water infrastructure includes:
| Recycled Water Facility / Program | Current Capacity (AF/year) | Target Capacity (2045) |
| Hyperion Treatment Plant (west LA) | 5,000 | 50,000 |
| Tillman Treatment Plant (valley) | 18,000 | 30,000 |
| Los Angeles City (other local facilities) | 12,000 | 18,000 |
| Indirect Potable Reuse (IPR) Programs | - | 30,000–50,000 |
| Total Recycled Water | ~35,000 | 170,000 |
The recycled water expansion will require infrastructure investment (dual distribution networks, customer retrofitting), but provides the utility with a supply not directly dependent on annual precipitation that grows independently of weather and regional water politics.
Peer Comparison and Benchmarking
| Metric | LADWP Water | San Diego Water | MWD (wholesale) | Phoenix Water |
| Service Population (M) | 4.0 | 3.2 | 19.0 | 2.2 |
| Water Operating Revenue ($M) | $1,057 | $652.4 | $1,820 | $492 |
| Water System Debt ($B) | $4.8–5.0 | $4.2 | $7.8 | $2.0 |
| Senior Lien Rating (Moody's) | Aa2 | Aa3 | Aa2 | Aa1 |
| Water System DSC | 1.94x | 1.54x | 1.72x | 1.65x |
| Recycled Water (% of supply) | 6% | 8% | 3% | 4% |
LADWP's DSC of 1.94–2.19x exceeds San Diego (1.54x) and MWD (1.72x) (FY2023–2024 agency reports), reflecting revenue growth and moderate rate increases. LADWP's recycled water program targets growth from approximately 6% to 25% of supply by 2045, comparable in scale to San Diego's program.
Credit Outlook and Future Considerations
Positive Factors:
- Approximately 714,000 water service connections serving 4 million people across 500 square miles
- Diversified water supply reducing dependence on any single source
- Recycled water program targeting expansion from ~35,000 AF treatment capacity to 170,000 AF by 2045
- Board-governed rate-setting authority with track record through four drought cycles since 1987–1992 (LADWP annual reports)
- LA Aqueduct remains a key asset providing 30–35% of regional supply based on LADWP's 2023 Urban Water Management Plan
- Investment-grade credit ratings supported by City of Los Angeles backing
Risk Factors:
- Severe California drought reducing imported water availability and increasing MWD costs
- Colorado River Compact water cuts further reducing Colorado River entitlements for California
- Environmental regulation risk affecting LA Aqueduct supply from Owens Valley and Mono Basin
- Capital program (recycled water expansion, seismic resilience, distribution renewal) increasing debt service
- Constrained debt service coverage limiting financial flexibility
- Customer demand decline affecting revenue base if conservation extends multi-year
- An emerging area of focus regarding rate increases in a politically sensitive customer base
Scenario Analysis: Under a baseline scenario with modest rate increases (1.5–2% annually) and continued capital spending execution, LADWP maintains adequate debt service coverage (1.5x+ minimum) through the planning horizon. Sensitivity analysis shows DSC could decline to 1.25x if imported water costs rise by 20% and consumption falls by 5% (LADWP financial model, FY2024), potentially triggering rating agency review. The Board's rate-setting authority and ongoing supply diversification investments may partially offset this scenario.
Outlook
LADWP's water system serves approximately 4 million people through 714,000 connections with diversified supply from five source categories and a recycled water program targeting 170,000 AF by 2045. LADWP maintains investment-grade credit ratings (Moody's Aa2, S&P AA+) with debt service coverage of 1.94–2.19x.
LADWP's water system operates as a regulated monopoly, which may appeal to bond investors seeking stable utility revenues from a large metropolitan area. Credit risks center on imported water supply vulnerability to California drought and Colorado River Compact dynamics, capital program funding requirements, and customer responses to rate increases in a politically sensitive customer base. Investors may wish to consider monitoring debt service coverage, imported water availability, and capital spending execution.
