1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a construction contract with Performance Pipelining, Inc., for public sanitary sewers for the Blueprint Hilltop 1 - Palmetto/Westgate Lateral Lining Project 2 project, CIP #650872-153002, in an amount up to $8,273,325.55; and to encumber funds with the Department of Public Service for construction administration and inspection services in an amount up to $2,000.00, for a total expenditure of $8,275,325.55.
This project is a Consent Order project. A Consent order is a negotiated agreement entered as a court order that is enforceable by the court. In 2005, the City of Columbus submitted its Wet Weather Management Plan to the Ohio EPA to bring the City in compliance with consent orders regarding the City’s sewer overflows. This project is an improvement identified in the Integrated Plan and in the 2015 Wet Weather Management Plan Update Report.
The work will include cleaning, televising, and lining sewer lateral lines in the Hilltop neighborhood (specifically in the Palmetto/Westgate sub-area). A sewer lateral line is an underground pipe, typically 4 to 6 inches in diameter that connects a private property’s plumbing system to the main public sanitary sewer line in the street. This work is needed to mitigate water in basement events and sanitary sewer overflows to the goal of a 10-year Level of Service (LOS). Over time, sewer lateral lines can develop cracks and leaks, allowing rainwater to get into the City’s sanitary sewers. The sanitary sewer system was not meant to hold rainwater, so when rainwater does get in, the pipes fill beyond their capacity. This overwhelms the system, potentially leading to sewage overflowing into rivers or backing up into basements. Lateral lining of sewer lateral lines places a resin-filled liner in the pipe, which is then hardened by filling it with hot water. This hardened liner then replaces the old pipe and prevents ra...
