Title
County of San Diego Sanitation District: Los Coches Sanitary Sewer Improvements from Maintenance Hole LSMH0555 to LSMH0599 Project
Description
The County of San Diego Sanitation District proposes the Los Coches Sanitary Sewer Improvement Project (proposed project) to improve and stabilize a section of an existing sanitary sewer pipeline. The proposed project will rehabilitate approximately 7,300 feet of an existing sewer collection system pipeline located between maintenance holes LSMH0555 to LSMH0599 below a section of Los Coches Creek. The proposed project follows the alignment of the existing sewer line, which is situated just south of Old Hwy 80 between its intersections with Gaucho Lane to the west and Flinn Crest Street to the east. The proposed work includes two main elements: installation of a composite lining within the existing pipe using the Cured-in-Place Pipe (CIPP) method. The CIPP liner serves to reinforce the existing pipe by precluding decay and providing additional structure for the pipeline. The second element includes reinforcement of three sections of pipeline through concrete encasement and a cover of Articulated Concrete Block to strengthen the cover and stability of streambed surfaces above the pipe section. These repairs and improvements would rehabilitate and stabilize the long-term safety and reliability of the sewer pipeline to reduce the likelihood of sewage spills and damage caused by pipe material degradation and erosion.
