Water Utility of the Future: Seattle Public Utilities

This report evaluates how Seattle Public Utilities manages separate enterprise funds, federal consent-decree obligations, aging networks, source-water protection, and long-term capital investment.

Summary Insight: Seattle Public Utilities manages distinct water and drainage-wastewater enterprises with separate financial and infrastructure obligations. The utility must coordinate source-water protection, aging network renewal, combined sewer overflow compliance, seismic resilience, wholesale supply, revenue bonds, and rate affordability across long-term capital programmes.

This Our Future Water Intelligence report provides an independent assessment of Seattle Public Utilities’ enterprise governance, consent-decree delivery, asset renewal, watershed protection, financial resilience, and capital sequencing.

The Five Strategic Pillars

Architectures: Water and drainage-wastewater enterprises

Examines how Seattle Public Utilities separates enterprise finances, capital obligations, revenue requirements, and operating responsibilities across water and drainage-wastewater services.
Enablement: Asset intelligence and digital control

Evaluates how Seattle Public Utilities uses asset-condition data, district metering, predictive maintenance, telemetry, and treatment controls to improve network performance.
Resolution: Combined sewer overflow compliance

Assesses how Seattle Public Utilities combines storage tunnels, treatment upgrades, conveyance improvements, and green infrastructure to meet federal overflow-reduction obligations.
Alignment: Climate, seismic, and source-water resilience

Reviews how Seattle Public Utilities aligns seismic hardening, watershed protection, wet-weather capacity, pipeline renewal, and emergency planning with long-term service reliability.
Capability Building: Revenue bonds and rate design

Explains how Seattle Public Utilities uses revenue bonds, wholesale agreements, reserves, user charges, and long-term rate planning to finance infrastructure while managing affordability.

Operational Excellence & Resilience

Seattle Public Utilities must coordinate concurrent investment across drinking-water and drainage-wastewater systems while meeting federal consent-decree obligations. The Ship Canal Water Quality Project, combined sewer overflow controls, pipeline renewal, facility upgrades, and watershed protection compete for capital within distinct enterprise structures.

Operational resilience depends on maintaining Cedar and Tolt source-water reliability while upgrading urban drainage, wastewater conveyance, and aging distribution assets. The report evaluates how asset planning, revenue bonds, wholesale income, rate design, seismic hardening, and regulatory schedules shape long-term service and financial performance.
