NSD Construction Zones

The District 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 the District at (707) 258-6000.

2017 Collection System Rehabilitation Project

 
Project Manager: Matt Lemmon

 

NapaSan has awarded the construction contract to K.J. Woods Construction to rehabilitate and replace aging pipelines in the Broadmoor Drive/Karen Drive, Foothill Blvd/Laurel Street, and South Minahen neighborhoods. The project will also include work on Rose Lane, Legion Avenue, and Jomar Drive. The general project areas are shown on the Project Map. The project will rehabilitate or replace over 2 percent of the sewer system which equates to roughly 5.7 miles of pipeline and 600 sewer laterals.  
Construction is expected to take place between May 2017 and October 2017 for the project as a whole, but different neighborhoods will be impacted at different times. Notifications have been mailed to residents in and near the project areas, and weekly project updates will be available on this webpage. 

 

The sewer pipelines will be rehabilitated by utilizing a combination of trenchless and open cut methods. Trenchless methods are utilized whenever possible because they minimize costs, construction time, and traffic disruptions compared to traditional open cut trenching.  The contractor will provide notice to residents and businesses whose sewer services are directly affected by the work both 48 hours and directly prior to the work. “No Parking” zones and traffic control will be implemented for safety reasons, however, access to properties will be maintained at all times for local residents and emergency services.  

 

Napa Sanitation District will make every effort to minimize the disruption caused by these construction activities.  If you have any questions or concerns please feel free to contact the Napa Sanitation District at (707) 258-6000.

 


Current Construction Location:

Work during the week of 9/11/17 will include Pine Street (west of Foothill) and Roosevelt Street (Pine Street to Laurel Street). The contractor will be conducting sewer main and sewer lateral rehabilitations in the project area.

MST Recycled Water Expansion Project

 

Project Manager: Andrew Damron

 

NapaSan has awarded the construction contract to TerraCon Constructors to construct the MST Recycled Water Expansion Project on Coombsville Road between Terrace Drive and Second Avenue.  The project consists of 1.4 miles of 8-inch and 18-inch pipeline in the westbound lane of Coombsville Road.  Construction will occur between June 9th and September 30th, 2017.  In order to minimize impacts to the public, the project has been scheduled to complete work in the vicinities of Silverado Middle School and Mount George Elementary School during the summer break period.  One-way controlled traffic with delays up to 15 minutes should be anticipated.

Soscol Avenue/Sousa Lane Trunk Sewer Rehabilitation Project


Project Manager: Andrew Damron

NapaSan will be rehabilitating a sewer pipeline on Eighth Street, Sousa Lane, and the stretch of Soscol between those two streets. This stretch of pipeline serves a large portion of NapaSan’s customers and conveys the majority of the dry weather flow through the sewer system. Camera footage of the pipeline has shown significant wear, and NapaSan wants to perform preventative maintenance since this pipeline is a crucial piece of the sewer system. Construction is scheduled to begin at the end of August when flow through this large diameter main will be low. NapaSan will be installing a new manhole, cleaning the sewer lines, and lining the sewer pipes as part of this project.

NapaSan will work hard to minimize traffic impacts, including keeping all lanes of Soscol Avenue open during commute hours and performing work on weekends. Message boards will be placed in the area prior to and during work to update residents about any traffic impacts and construction plans. Notifications have been mailed to residents in and near the project areas, and weekly project updates will be available on this webpage.

The sewer pipelines will be rehabilitated by utilizing a combination of trenchless and open cut methods. Trenchless methods are utilized whenever possible because they minimize costs, construction time, and traffic disruptions compared to traditional open cut trenching. The contractor will provide notice to residents and businesses whose sewer services are directly affected by the work both 48 hours and directly prior to the work. “No Parking” zones and traffic control will be implemented for safety reasons, however, access to properties will be maintained at all times for local residents and emergency services.

Napa Sanitation District will make every effort to minimize the disruption caused by these construction activities. If you have any questions or concerns please feel free to contact the Napa Sanitation District at (707) 258-6000.

Current Construction Location:

Work will be done on Soscol Avenue between Sousa Lane and Eighth Street. This will result in a lane closure on Soscol Avenue, but all lanes will be open during commute hours. Sewer line cleaning, lining, and manhole work will occur between September 5th and September 21st, which will result in a lane closure along Soscol Avenue that will not be in effect during the morning or evening commute.
