The Montezuma/Mid-City Pipeline Phase 2 project represents a major investment in regional water infrastructure, with construction scheduled to run from April 2025 through October 2027.
The project includes the installation of a 66-inch diameter redundant water transmission main extending from the Alvarado Water Treatment Plant to the intersection of 69th Street and Mohawk Street.
A key technical component involves a specialized tunneling operation beneath Interstate 8. Crews are using a boring pit near Alvarado Road and a receiving pit at Lake Murray Boulevard and Wisconsin Avenue to safely complete the underground crossing.
The pipeline utilizes cement-lined and coated steel pipe designed for long-term durability, ensuring reliable water delivery for decades.
“This project represents an important investment in long-term water reliability for the region,” said Len Kody, marketing and communications manager at W.A. Rasic Construction. “Our team is focused on delivering complex infrastructure safely and efficiently while maintaining strong coordination with local agencies and the surrounding community.”
In addition to pipeline installation, the project extends into the city of La Mesa, where crews are replacing sections of an existing 8-inch concrete sewer main and completing roadway rehabilitation along key corridors, including 70th Street and Lake Murray Boulevard.
Construction activities are being carefully coordinated to manage traffic impacts, with detours and temporary closures implemented to ensure safety and minimize disruption.
The project builds on the company’s broader portfolio of infrastructure work across California, including recent tunneling and utility projects in Los Angeles County.

Founded in 1978, W.A. Rasic Construction specializes in underground utilities and heavy civil infrastructure, serving both public agencies and private clients across the western United States.
The San Diego pipeline project underscores the company’s continued focus on delivering critical infrastructure that supports system resilience, regional growth and environmental sustainability.
As climate pressures and population growth increase demand on water systems, projects like the Montezuma/Mid-City Pipeline are expected to play a key role in ensuring long-term reliability for communities across Southern California.
