Carolina Trunk Sewer Work Zone 02 Rehabilitation

The Carolina Sewer Repair Project involved the rehabilitation of over 750 feet of 51” cast-in-place monolithic concrete sewer located along S Macadam Avenue between S Mitchell Street and S Sweeny Street in the City of Portland, Oregon. SEKISUI SPR Americas worked with the City of Portland and their consultant Brown and Caldwell during the design phase to review the project scope, project challenges, and the key objectives of the rehabilitation method to be specified. This involved the review of CCTV and other condition assessment reports, understanding the various constructability challenges including flow conditions and radius bends within the host pipe. The key drivers for the project were to verify that hydraulic capacity would be maintained post-rehabilitation and that the liner would provide a fully structural repair solution.

San Marcos Interceptor Replacement – Phase 1

The San Marcos Interceptor Sewer is a major sanitary sewer transport line which combines with other lines to convey flows to the Encina Water Pollution Control Facility in Carlsbad for treatment. The replacement of the San Marcos Interceptor provides additional capacity for development projections expected in the areas. The project was initially designed in 1999, but was put on hold over environmental impact concerns. More recently, improvements along San Marcos Creek and the economic downturn caused additional delays. The project was designed in two phases - Phase 1 consisted of replacement of the existing 21-inch diameter sewer tunnel with two tunnel portions and cut and cover installation of new pipelines. Phase 2 will extend the work of Phase 1.
