The Sewer Rehabilitation Plan Phase 1, Sewer Main Replacement Project 1 (at Euclid Street, Pinehurst Court, Nelson Street, Pine Street, Pearl Street, Allen Drive, Stanford Avenue, Euclid Park, Trask Avenue, and Wilson Street) is one of many projects designed to address defective sewer pipe throughout the City under the GGSD System Evaluation and Capacity Assurance Plan of 2012. The condition of the pipe is categorized, severe, major, moderate, minor and no defect and the Plan prioritizes pipes in severe and major condition. The GGSD System Evaluation and Capacity Assurance Plan identified Project No. 7840 as one of the high priority projects. The rehabilitation plan complies with the Regional Water Quality Control Board’s Waste Discharge requirements.  A location map is attached identifying this project.

The scope of work also includes replacing sections of existing asbestos cement pipe (ACP) water mains with PVC C-900 pipe.
