This is a hydraulic profile schematic document for the City of Palo Alto Utilities Department (CPAU) water distribution system, prepared on February 24, 2025. The document presents a comprehensive technical illustration of CPAU's potable water infrastructure across nine pressure zones, depicting the system's complex network of reservoirs, booster pump stations, pressure-regulating stations, wells, and interconnecting water mains ranging from 12 to 36 inches in diameter. Key infrastructure components include the Mayfield Reservoir (4 MG capacity), El Camino Reservoir (2.5 MG), Corte Madera Reservoir (1.5 MG), Boronda Reservoir (1.0 MG), Park Reservoir (1.5 MG), Dahl Reservoir (1.0 MG), and Monte Bello Reservoir (1.5 MG), along with associated pump stations and eight active wells including Matadero, Fernando, Peers Park, Rinconada, Library, Eleanor Pardee Park, Hale, and El Camino. The system incorporates multiple interties with neighboring agencies including Mountain View, Stanford, Purissima Hills, and East Palo Alto, as well as connections to SFPUC Bay Division pipelines, with maximum day demand (MDD) and normal firm flow (NFF) capacity noted for various pressure zones.

The schematic illustrates hydraulic gradeline (HGL) profiles at elevation 310 for external SFPUC connections and depicts the elevation-based operation of the water distribution system across geographically diverse service territory spanning from lowland areas near Embarcadero Road and East Bayshore Road to higher elevation zones in the foothills. Pressure regulation stations are strategically positioned throughout the system, including Charleston, Hillview, Foothills Entrance, Foothills 6, Foothills 7, and Hewlett PR stations, to maintain appropriate pressure across the nine distinct pressure zones. The document serves as a technical reference for CPAU's Water System Master Plan project, which aims to evaluate system adequacy, identify deficiencies and capital improvement needs, and provide hydraulic modeling support for infrastructure planning over a 20-year planning horizon.
