Report
BACKGROUND
The Water & Sewer Utilities Department manages the Sanitary Sewer Condition Assessment Program (Condition Assessment Program) using the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP) guidelines. The PACP guidelines are used to inspect the sanitary sewer collection system, evaluate defects, and prioritize repairs for approximately 270 miles of pipeline in the City's sanitary sewer collection system. The defects are rated on a scale of 1 to 5 based on the significance of the defect, with 1 being minor and 5 being the most significant. Currently, the City is prioritizing the repair of defects that are rated 5.
While Water & Sewer Utilities Department crews perform spot repair work on sanitary sewer mains, significant repairs that are complex due to factors such as traffic control, repair length, pipe size, and pipe depth, are referred to the Department of Public Works (DPW) to develop design and construction documents for a public works contract.
There are approximately 38 sanitary pipeline segments that are identified for repairs. These segments have been packaged into two construction contracts, Phase 1 and Phase 2. The work was separated into phases to: 1) combine similar work in terms of scope, permitting and environmental impact, 2) obtain competitive pricing and 3) complete the work more quickly.
The Sanitary Sewer Condition Assessment Repairs Project - Phase 1 (Project) will repair defects in the sanitary sewer collection system identified through the Condition Assessment Program. The scope of work for the Project involves replacing or rehabilitating sanitary sewer mains along 26 pipeline segments at various locations citywide. The sewer repairs will be comple...
