Lift Station Number 2 (LS2), which was constructed in 1953, needs replacement. J.R. Filanc Construction, Inc. (Filanc) won the contract. The project site encompasses approximately 1.2 acres along Country Club Drive in the City of Laguna Beach in Southwestern Orange County. Filanc received the notice to proceed in May 2023, and completion is expected in March 2026.

Together with Trench Shoring’s assistance, Filanc decided to go with a slide rail system. The slide rail system consists of 16-foot by 16-foot shoring box sections, which can be used in conjunction with other sections to protect a trench as needed. The excavation was 16 feet wide and 80 feet in length, with a depth of 16 feet. The City’s 24-inch asbestos concrete pipe was at the bottom of the 16-foot-deep excavation. After the vault and bypass piping was placed, they had to excavate five feet or more below the existing pipe to place anchor blocks for the line stop. To go below the existing pipe, they utilized aluminum manhole boxes in  combination with some sheet piles. Experts from Trench Shoring Company analyzed the excavation and made a recommendation and eventually a designed solution. We were also onsite to supervise the initial installation.
