Network Efficiency and Water Losses: San Francisco Public Utilities Commission
Network Efficiency and Water Losses: San Francisco Public Utilities Commission
The San Francisco Public Utilities Commission manages network efficiency across a regional conveyance system and a separate in-City distribution estate, both carrying advanced age rather than published leakage benchmarks as their defining condition.
This report frames SFPUC network efficiency as a renewal-led and data-led operating challenge, with leakage exposure shaped by asset age, metering coverage, capital sequencing, and rate affordability rather than a single published non-revenue water benchmark.
Target Audience
- Utility Executives & System Operators: Understand how Hetch Hetchy asset age shapes leakage exposure and renewal priorities.
- Regulators & Policymakers: Examine how the Affordability Policy disciplines capital pacing and efficiency commitments.
- Infrastructure Investors & Financiers: Assess how the $11.8 billion capital plan reframes delivery and debt risk.
Report Deliverables
- Network Loss Context: Provides analysis of leakage exposure across regional conveyance and in-City distribution assets.
- Metering Intelligence: Delivers insight into advanced metering coverage and customer-side leak detection capability.
- Capital Risk View: Enables evaluation of renewal financing, debt exposure, and delivery sequencing.
- Governance Assessment: Provides assessment of affordability, charter planning, and environmental justice commitments.
- Operational Framework: Delivers frameworks for comparing asset age, monitoring maturity, and resilience investment.
The Five Strategic Pillars
-
Architectures: Leakage Profile and Trends
Assesses how ageing regional conveyance and local distribution assets define leakage exposure where published loss benchmarks are limited.
-
Enablement: Non-Revenue Water and Loss Drivers
Examines how metering precision, consumption monitoring, and supply diversification influence apparent and real-loss management.
-
Resolution: Network Condition and Asset Age
Evaluates the renewal burden created by long-lived water, wastewater, storage, and treatment infrastructure.
-
Alignment: Pressure Management and Operational Controls
Reviews operational control through combined-system flow management, treatment commissioning, and stormwater resilience investment.
-
Capability Building: Metering and Monitoring Infrastructure
Analyses the Aclara fixed-network metering base and its role in hourly consumption visibility and leak detection.
Operational Excellence & Resilience
San Francisco Public Utilities Commission operates an integrated water network supported by regional conveyance, in-City distribution, and combined wastewater infrastructure. Performance is achieved through asset renewal, advanced metering, and sequenced capital delivery. This is further supported by the Aclara fixed-network advanced metering infrastructure. Key performance is reflected in nearly 178,000 water accounts with meter transmission units in place. This is reinforced by the $11.8 billion ten-year capital plan across Water, Wastewater, Hetch Hetchy Water, and Power systems.
The adopted FY 2024-25 to FY 2033-34 ten-year capital plan funds renewal, regulatory compliance, climate adaptation, and multi-enterprise resilience across SFPUC systems.
About the Author
Expert Briefing: FAQs
It assesses SFPUC network efficiency, water losses, asset condition, metering maturity, and investment risk. This is supported by more than 1,250 miles of in-City distribution pipelines. This is delivered through analysis of the Hetch Hetchy Regional Water System and the in-City distribution estate.
Asset age is the defining condition variable behind SFPUC leakage and reliability exposure. This is supported by the Hetch Hetchy Regional Water System operating at approximately 135% of anticipated useful life. This is delivered through the Water System Improvement Program and related renewal planning.
Metering improves customer-side visibility and supports faster leak detection. This is supported by hourly meter readings across nearly all of San Francisco's approximately 178,000 water accounts. This is delivered through the Aclara Fixed Network Advanced Metering Infrastructure STAR System.
The main investment signal is the scale and debt intensity of SFPUC renewal funding. This is supported by the $11.8 billion ten-year capital plan. This is delivered through the multi-enterprise capital programme covering Water, Wastewater, Hetch Hetchy Water, and Power systems.
