Drainage Pipe Lining Project 2025

​Project Description​

The project will rehabilitate the pipe with Cured-In-Place Pipe (CIPP) lining.  CIPP lining installs an inner lining within the existing pipe creating a new pipe without the complications of traditional remove and replace construction.  The project will line 15 pipe sections totaling 1,550 lineal feet to mitigate corrosion, root intrusion, and risk of pipe failure.

During the lining installation, there will be a noticeable odor, often described as plastic or glue-like. The odor is temporary and typically dissipates within hours of installation. ​


Project Updates

The project design was finalized in May 2025 and the Sacramento County Board of Supervisors approved putting the project out to bid on May 13, 2025.  The project received three bids on June 12, 2025.  The project was awarded to the lowest bidder Lamassu Utility Services Inc. on June 26, 2025.
