Martinez IV Collection System CIP – Project 29

Martinez IV Collection System CIP – Project 29

This project is for the design and construction of a large diameter gravity sewer line that will connect the Millican Grove Lift Station to the Martinez IV Wastewater Treatment Plant. This line was identified as Project 29 in the original Martinez IV Service Area Master Plan completed in FY 2017-18. Construction of this line is necessary to accommodate existing and planned development within the service area. Additionally, this line enables more connections in the service area north of Interstate 10 (I-10). Decommissioning of the Graytown Road and Millican Grove Lift Stations will also be part of this project.
