North Coast Interceptor Reach 5 Replacement Project

The City of Laguna Beach is planning the replacement of approximately one mile of the North Coast Interceptor Reach 5 pipeline located in Aliso Canyon, extending from Coast Highway to the South Orange County Wastewater Authority Coastal Treatment Plant. This aging infrastructure, originally constructed in the 1970s and owned by SOCWA but operated and maintained by the City of Laguna Beach, consists of a gravity-fed system incorporating force mains and inverted siphons. The replacement will employ a combination of construction methods including open trench excavation, horizontal directional drilling, and slip lining to minimize environmental disruption and ensure long-term durability. The project aims to modernize a critical wastewater conveyance system that serves the region, addressing potential failures and operational inefficiencies of the decades-old pipeline. The initiative is part of a broader effort to maintain reliable utility services and comply with current environmental and infrastructure standards. The project is forecasted to be released in August 2026 and will be carried out within Laguna Beach, California, with the primary point of contact being Ulises Escalona, Senior Project Manager, who can be reached via phone or email for further inquiries. The planned methodology balances engineering effectiveness with environmental stewardship, particularly given the sensitive topography of Aliso Canyon. No set-aside information or NAICS code is currently specified, and formal solicitation details have not yet been published, though the project is anticipated to proceed through standard public procurement processes.
