TUD Begins Sewer Pipeline Rehabilitation Project in Sonora

The Tuolumne Utilities District (TUD or District) will begin the 2021 Cured-In-Place-Pipe (CIPP) Sewer Rehabilitation Project next week in Sonora. This high priority project was identified in the District’s Capital Improvement Plan (CIP) and consists of the installation of 4,517 lineal feet of cured-in-place-pipe ranging from 8” to 16” diameters at various locations within the District’s service area.

In October 2020, the District’s Board of Directors awarded the CIPP contract to Southwest Pipeline and Trenchless Corporation in the amount of $208,192. The Cured-In-Place-Pipe project will start next week on Monday, March 1st through Friday, March 5th in Sonora at the locations listed below:

March 1-3, 2021 – On Snell Street from the intersection of School Street to Bonanza Road. One-way traffic controls will be in place on Snell Street. Project work hours: 7:00 AM to 5:00 PM.

March 3-4, 2021 – At the intersection of School Street to Snell Street. One-way traffic controls will be in place on School Street. Nighttime project work hours: 10:00 PM to 7:00 AM.

Motorists can expect 10-minute traffic delays with one-way traffic controls in place but are asked to avoid these areas if possible.

The District owns and operates over 140 miles of collection sewer pipeline. Using the CIPP technique has proven to be a cost-effective alternative to dig and replace pipeline methods. TUD appreciates the community’s cooperation and support as it works to improvement the District’s collection sewer system and asks motorists to drive with caution through the project construction zone.
