2022 Collection System Rehabilitation Project

Project Manager: Karl Ono, kono@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.
