Explanation
1.0 BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a construction contract with Kenmore Construction Co., Inc. for the Hap Cremean Water Plant (HCWP) Sludge Disposal Line Improvements - Part III Project; in an amount up to $3,220,144.90; for Division of Water Contract Number 1149.
Work on this project consists of various improvements along the Hap Cremean sludge line to improve line performance. Improvements include the removal and/or rehabilitation of air release vaults and valves, installation of new sludge force main piping and other such work as may be necessary to complete the contract, in accordance with the plans and specifications.
Planning area: “99-Citywide”; HCWP provides service to several Columbus communities.
2.0 ECONOMIC IMPACT/ADVANTAGES; COMMUNITY OUTREACH; PROJECT DEVELOPMENT; ENVIRONMENTAL FACTORS/ADVANTAGES OF PROJECT:
The HCWP Sludge Disposal Line was constructed in 1979 and transports process residuals (lime and alum sludge) from HCWP to the McKinley Quarry for disposal. The sludge line has experienced recent lime slurry releases from various valves on the line. The 17.4 miles - 12 inch ductile iron pipe was originally constructed outside paved road areas but due to various road widening projects during the life of the line much of it is now within pavement and many of the valve vaults have been covered by pavement and are inaccessible. This project will allow the City to better identify the line location and to provide appropriate preventative maintenance to reduce releases to the environment. Without the ability to transport or store process residuals HCWP will be unable to continue to treat water.
