1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a professional engineering services agreement with Hazen and Sawyer, for the Residuals Management Plan Update, in an amount up to $1,120,100.00, for Division of Water Contract No. 2061.

Water treatment residuals from the City’s three water treatment plants are sent to the McKinley Avenue quarry for disposal. At some future point, the storage capacity of the quarry will be exhausted and alternative methods of disposal or reuse will be needed to meet the City’s residuals handling needs. This project will update the Division’s 1995 Residuals Management Plan.

The primary objective of the update is to identify long-term solutions for handling and disposal/reuse of treatment residuals generated at the City’s three water treatment plants. Work to be conducted includes engineering planning and study services to: characterize existing residual streams; estimate remaining useful life of current residuals handling methods; identify handling / disposal / reuse options; perform market analysis for beneficial reuse options; develop conceptual designs for selected options to assess suitability and support cost estimating; perform life cycle cost analysis for selected options; develop an implementation roadmap for recommended solutions; and other engineering services as outlined in the scope of services.

The Community Planning Area for this project is “City wide” because the study is related to all three water plants that serve the greater Columbus area.

2. ECONOMIC IMPACT/ADVANTAGES; COMMUNITY OUTREACH; PROJECT DEVELOPMENT; ENVIRONMENTAL FACTORS/ADVANTAGES OF PROJECT: Water treatment facilities produce large volumes of residuals on a daily basis that must be continuously disposed of or reused. Any disruption to the residuals handling operation can result in a shutdown to the water treatment system; thus, residuals handling is a critical component of the City’s...
