NapaSan Construction Zones
NapaSan conducts a regular sewer system maintenance program. You may see us on the streets, repairing, replacing, or cleaning sewer lines or recycled water pipes. We apologize for any inconvenience and appreciate your patience while we work to keep our system operating effectively!
Refer to the information below to find out where our current construction projects are happening. If you have any questions or concerns, please call NapaSan at (707) 258-6000.
Browns Valley Trunk Sewer Project
Project Manager: Andrew Damron, email@example.com
Project Background: The Browns Valley Trunk Project is designed to intercept wastewater from Browns Valley and Southwest Napa and divert the flow away from sewer lines that are over capacity via a new 3-mile pipeline that will deliver the wastewater to NapaSan for treatment. For additional background information, visit our Browns Valley Trunk Project page.
Current Construction Location: During the week of January 25th, centerline staking will take place along First Street and Browns Valley Road. Tunneling activities under Highway 29 will continue this week. Manholes will be installed at the Highway 29 under crossings. Work in the medians will take place at various locations.
During the week of February 1st, centerline staking will continue along First Street and Browns Valley Road. Pipeline installation will occur near the Old Sonoma Road and Freeway Drive intersection. Potholing and median work will take place at various locations. Tunneling activities under Highway 29 will continue this week.
Summer 2020 Sewer Rehabilitation Project
Project Manager: Simon Kobayashi, firstname.lastname@example.org
Project Background: The Summer 2020 Sewer Rehabilitation Project project is essential to reduce the amount of maintenance calls and the potential for sewer overflows in your area and is necessary for the operation of our sewer system.
Nu-Line Technologies, Inc. will begin construction in April and continue through October. All work will be done in compliance with the Construction Site Requirements set forth in the Napa County Shelter-in-Place Order to ensure worker safety.
The five primary project areas are: Pear Tree Lane, Redwood Road, Jefferson Street, the Old Sonoma Road Highway Crossing, and Browns Valley Road. The project areas were selected due to the deteriorated condition of aging sewer pipes. NapaSan will be repairing or replacing these aging sewer pipelines that allow stormwater and groundwater to infiltrate into the sewer system. Reducing this infiltration helps to decrease the possibility of sewer overflows and spills. Approximately 340 sewer laterals will be repaired or replaced as part of this project. Through this project, 5.6 miles of pipeline (approximately 2.1% of the total sewer system) will be rehabilitated or replaced.
As always, NapaSan will work to minimize negative impacts to pavement conditions whenever possible throughout this project. Wherever possible, pipelines will be rehabilitated using cured-in-place pipe, which is less invasive to streets than pipe bursting or open cut methods. Trenchless methods also minimize costs, construction time, and traffic disruptions compared to traditional open-cut trenching.
Current Construction Location: From January 19th through January 29th, sewer main rehabilitation work will take place in the following locations:
- Freeway Drive
- Robinson Lane
- Pueblo Avenue between Trotter Lane and Soscol Avenue
- Redwood Road
- Browns Valley Road near Thompson Avenue, and between Westview Drive and McCormick Lane
- Hudson Lane
