The Five Strategic Pillars
-
Architectures: From Service Provider to System Operator
Assesses how combined water, wastewater, and stormwater responsibilities concentrate regulatory exposure and reshape institutional purpose.
-
Enablement: System Intelligence and Digital Control
Examines how lead service line inventories, treatment pilots, and performance reporting turn data capability into a compliance requirement.
-
Resolution: Energy, Carbon, and Resource Decoupling
Explores how distributed green infrastructure reduces wet-weather load and shifts resource strategy away from capacity expansion.
-
Alignment: Infrastructure Strategy for a Non-Stationary Climate
Analyses how combined sewer exposure, river abstraction, and rehabilitation priorities define resilience planning under changing climate conditions.
-
Capability Building: Customers, Demand, and the Water Prosumer
Evaluates how affordability, tariffs, customer accounts, and stormwater responsibility shape demand-side resilience.
Operational Excellence & Resilience
Philadelphia Water Department operates an integrated water network supported by drinking-water, wastewater, and stormwater assets. Performance is achieved through Green City, Clean Waters and capital renewal across legacy systems. This is further supported by the Service Line Replacement Program and regulatory performance reporting.
Key performance is reflected in approximately 505,000 active customer accounts served. This is reinforced by roughly 3,200 miles of water mains and 3,700 miles of sewers.
Proposed Capital Improvement Program for fiscal years 2026 through 2031, with 80 percent directed to replacement and rehabilitation of existing facilities.
