Adopt a Resolution approving plans and specifications and authorization for the City Clerk to advertise to receive bids for rehabilitation of wastewater pipelines in the Carlsbad Village area, Project No. 5503. Executive Summary Many of the wastewater pipelines in the Carlsbad Village area have reached the end of their useful life and are in need of rehabilitation. The defects in these locations include cracked and broken pipe, root intrusion, and groundwater infiltration which increase the risk of sewage blockage and overflow spills. Trenchless methods for pipeline repair will be used to minimize disruption to the community. Staff recommends approval of the project plans and specifications, and authorization to advertise for construction bids of Project No. 5503. Discussion Inspection of the wastewater pipelines by closed circuit television has shown many of the pipelines in the Carlsbad Village area have reached the end of their useful life. This project includes the rehabilitation of approximately 7,000 lineal feet of 6-inch and 8-inch diameter gravity wastewater pipelines now in disrepair, located in the Carlsbad Village Barrio and beach area (Exhibit 2). The project includes the installation of cured-in-place pipe liner (CIPP) which will result in a full structural restoration of those pipelines. The pipelines' useful life will be extended an additional 30 to 50 years. The CIPP method of rehabilitation is a trenchless method of construction. The application of trench less rehabilitation methods in this project reduces construction cost, construction duration and impacts to the community when compared to the alternative, conventional dig and replace methods of repair. The CIPP method will significantly reduce traffic and pedestrian impacts, minimize or eliminate pavement damage, as well as damage to adjacent utilities and structures.
