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. 

2022 Collection System Rehabilitation Project

Project Manager: Gavin Glascott, GGlascott@napasan.com

Project Background: NapaSan 2022 Collection System Rehabilitation Project will begin this spring.   The project is essential to reduce the amount of maintenance calls, decrease the potential for sewer overflows in the project area, and improve the operation of our sewer system.

NapaSan’s contractor, Southwest Pipeline and Trenchless Corporation, Inc., has started work and work is expected to continue through October 2022. The project area was selected due to the deteriorated condition of aging sewer pipes and the high amount of inflow and infiltration of water into the sewer system during the winter months. The majority of the sewer pipelines in the project area are between 40 and 60 years old.  Reducing infiltration into the sewer system helps to decrease the possibility of sewer overflows and stops clean rain and groundwater from flowing to NapaSan for unnecessary treatment.  

Current Construction Location:      

During the week of September 26:  No sewer mainline rehabilitation will be performed this week.  Sewer cleanout installations and lateral rehabilitation will occur on Trower Avenue west of Highway 29, and Solano Avenue north of Trower Avenue. 

Sewer lateral rehabilitation will occur on El Centro Avenue west of Jefferson Street, Jefferson Court, and Jefferson Street north of El Centro Avenue.
