Capital Improvement Program

Alta Heights TankThe 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.
