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.

Special pages have been created to highlight some recent projects of significance. Just view the following page for detailed descriptions, photos, and videos:
In the second half of 2013, the City of Napa replaced several aged, leaking, and undersized freeway crossings with new mains to improve circulation within the water system.
In the first half of 2012, the City of Napa replaced a 7.400-foot section of water main on the west side of Highway 221 from Napa Valley College south to Kaiser Road, resulting in a major improvement in how water moves through our distribution system.
The Edward I. Barwick Jamieson Canyon Water Treatment Plant (WTP) has been improved and can now take beneficial use of the City's existing State Water Project entitlements, meet daily water demands alone for longer periods throughout the year, and comply with increasingly stringent water quality regulations.
