Capital Improvement Program

The City of Napa Water Division maintains a significant number of facilities needed to deliver high-quality drinking water to local homes and businesses. Treatment plants, pipelines, pump stations, storage tanks, valves, hydrants, and meters all play a role. Much of the system has been in service for 60 years or more. A 20-year capital improvement plan now prioritizes the system improvements that are needed to maintain a high level of service and avoid the disruptions and large costs associated with failing infrastructure.

Current and Upcoming Projects:

2020 Upper Alta Heights Water System Improvements Project

The Upper Alta Heights Water System Improvements Project (PDF) involves water tank and pump station improvements which primarily impact water customers at 527-707 Montecito Blvd., 262-286 Monte Vista Drive, Monte Vista Court, and 75-81 El Cortez Drive.

2019 Water Main Freeway Crossings Project (FEMA-Funded)

In the summer of 2019, the City of Napa began replacing several Highway 29 freeway crossings that broke during the 2014 South Napa Earthquake with new mains to reestablish circulation within the water system.

Conn Dam Water Spillway Repairs - Phase II

In November 2018, the City addressed damage requiring immediate repair to Conn Dam Spillway (Phase I).  The work performed under Phase I involved the repair of edge spalling and crack sealing and was completed in December 2018; the repairs completed as part of Phase I withstood subsequent heavy winter rains, prompting the City to continue with Phase II repairs.

On September 27, 2019, the City received the below proposals for Design-Build project delivery of Phase II repairs.
