Explanation
1. BACKGROUND:
This legislation authorizes the Director of Public Utilities to enter into a professional engineering services contract with URS Corporation-Ohio, Inc., in connection with the Southerly Wastewater Treatment Plant Primary and Aeration Tank Improvements 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.

This project will add two additional aeration tanks and two additional primary settling tanks. The new aeration tanks will provide the train with the biological treatment capacity equal to the West or East Trains. The new aeration tanks will have step feed piping and control system that will match the West and Center Train systems. In addition, it will provide the addition of a common primary effluent channel to be located north of the East Train aeration tanks and step feed piping. The influent channel and utility tunnel will be extended for the aeration tank influent feed and effluent discharge to the mixed liquor channel.

The new settling tanks will have sludge pumps and piping connecting to the existing primary sludge line.
