Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a construction contract with Complete General Construction Company for the Noble and Fourth Inflow Redirection project, CIP #650790-100000, in an amount up to $2,168,782.20; 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 $2,170,782.20).
This contract is for the redirection of public sources of inflow of six acres of the Noble / 4th sewer shed. In order to facilitate the redirection of the inflow, this contract includes the construction of 502 feet of 10-inch sanitary sewer along Noble Street between 5th Street and 4th Street. The new 10-inch sanitary sewer will connect to an existing 72-inch combined sewer at the intersection of Noble and 4th. This project will also repurpose the existing 24-inch combined sewer on Noble Street to a dedicated storm sewer by abandoning CSO 510, diverting all flows to the storm 72” storm sewer. By separating the storm and sanitary sewer, the flows in the sanitary can be relieved to reduce overflows into the storm sewer. The project will reduce inflow and infiltration to the City’s sanitary sewer system thus mitigating sanitary sewer overflows to basements and waterways.
The City of Columbus and the State of Ohio entered into a consent order in August of 2002 to resolve sanitary sewer overflow (SSO) related concerns for the City’s sanitary sewer system. The consent order requires the City to develop and implement a program to provide adequate capacity in the collection system, taking all feasible steps to address SSO’s. This is one of the projects implemented to comply with the consent order. The improvements must be completed by July 1, 2025, to comply with the consent order.
The Community Area for this ordinance will be 55, Downtown.
