The Morena Northern Pipelines and Tunnels project will connect to the Morena Pipelines Middle Alignment to the south and the North City Water Reclamation Plant to the north.
This project includes portions of two 10.5-mile pipelines: one 48-inch wastewater pipeline, which will carry wastewater north to the North City facilities for purification, and one 30-inch brine line that will carry the biproduct from water purification south to the Point Loma Wastewater Treatment Plant. This project begins on Genesee Avenue and Appleton Street and continues on Genesee Avenue, Nobel Drive, Towne Centre Drive and Executive Drive. Tunneling will be completed at Genesee Avenue and State Route 52 (San Clemente Creek), at Genesee Avenue and Rose Creek Canyon, and under Interstate 805.
Project Started: June 2021
Anticipated Completion: 2024
Construction for this project will primarily take place on weekdays on weekdays at night from 7 p.m. to 5 a.m., except on Nobel Drive when construction will occur from 7 a.m. to 4 p.m. Tunneling work will be 24/7 with adherence to noise requirements.
