Upper Northwest Interceptor Manholes

Location: North Highlands, CA

Start Date: August 2007

End Date: January 2009

Working as a Subcontractor on a major interceptor project for Sacramento County, our portion of work consists of constructing 18 closure manholes after the pipeline/tunnel work is completed. We also have two major "turning" structure to construct. All structures are protected with a "T-Lock" lining system.

A unique feature of this project is the structure will be constructed in the confines of a sheet-pile shoring system and averages approximately 30' deep.
