1. BACKGROUND:
This legislation authorizes the Director of Public Utilities to enter into a professional engineering services agreement with CH2M Hill, Inc., in connection with the Southerly Wastewater Treatment Plant Sludge Thickening Improvements and Additional Renovations Project.
The City of Columbus has developed a Wet Weather Management Plan that identifies the preliminary sewer system and wastewater treatment facility capital improvements needed to fully address the city's wet weather overflows and many basement backup problems across the city.

The existing gravity thickeners have reached their treatment capacity, with no ability for future capacity and the thickening centrifuges are at the end of their useful life. With the evaluation of sludge thickening processes and technologies, a reliable, cost effective system will be selected.

The committee ranked the proposals on quality, feasibility and cost. After careful consideration, the committee recommended that CH2M Hill, Inc., be selected to provide the engineering services for this project, a recommendation in which the Director of Public Utilities has concurred.
