This is a hydraulic profile schematic document for the City of Palo Alto Utilities (CPAU) water distribution system, dated February 24, 2025, depicting the comprehensive water infrastructure network across nine pressure zones. The schematic illustrates the system's seven reservoirs with capacities ranging from 1.0 to 4.0 million gallons (Mayfield, El Camino, Corte Madera, Boronda, Park, Dahl, and Monte Bello), eight active wells (Matadero, Fernando, Peers Park, Rinconada, Library, Eleanor Pardee Park, Hale, and El Camino), multiple booster pump stations, and pressure regulating stations distributed across elevations spanning from 45 feet to 2,406 feet. The distribution system encompasses 232 miles of water mains ranging from 6 inches to 36 inches in diameter, with interconnections to external water sources including the SFPUC Bay Division pipelines (HGL = 310), Mountain View interties, Stanford interties, East Palo Alto intertie, and Purissima Hills interties. Key demand parameters are documented for each pressure zone, with Maximum Day Demand (MDD) values ranging from 21 to 11,000 gallons per minute and Normal Full Flow (NFF) values from 1,500 to 7,500 gallons per minute across the various zones.

The hydraulic profile serves as baseline infrastructure documentation for the Water System Master Plan Update RFP anticipated for release in May 2026. This technical schematic establishes the existing system configuration against which prospective municipal water master planning consultants will evaluate aging infrastructure conditions, seismic vulnerabilities, system interconnections, and capital improvement requirements. The document reflects the current operational status of CPAU's water delivery infrastructure and will inform the comprehensive master plan update that builds upon the 2015 Water System Pipe Replacement Plan, which previously recommended a $19 million seismic improvement program (SIP-3 option) over ten years.
