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, firstname.lastname@example.org
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 October 26th, pipeline installation work will continue on Sycamore Street. Pipeline installation will also take place along Freeway Drive in the area of Old Sonoma Road to Elm Street. Freeway Drive from Old Sonoma Road area to Pine Street will be closed to through traffic, but residents will have access to their driveways. A detour will be in place directing drivers to use Pine Street, Foothill Boulevard, and Old Sonoma Road to avoid the construction area. Pipeline testing will take place along Freeway Drive from the Laurel Street/Kilburn Avenue area to First Street. Tunneling work is anticipated to begin under Highway 29 at Old Sonoma Road. Please plan for traffic delays and parking restrictions in all these areas. If possible, use an alternate route to avoid these construction zones.
During the week of November 2nd, pipeline installation will continue along Sycamore and move to South Jefferson. Pipeline installation will continue along Freeway Drive from vicinity of Elm Street to Pine Street. Freeway Drive will be closed to through traffic, but residents will have access to their properties. Tunneling under Hwy 29 from Old Sonoma Rd will continue. Please plan for traffic delays and parking restrictions in all these areas. If possible, use an alternate route to avoid these construction zones.
Summer 2020 Sewer Rehabilitation Project
Project Manager: Simon Kobayashi, email@example.com
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 October 5th through October 30th, sewer main rehabilitation work will occur on Browns Valley Road between Thompson Avenue and Hudson Lane.
