Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an engineering agreement with Andover Associates for professional engineering services for the Southerly Wastewater Treatment Plant (SWWTP) Post Aeration Diffuser Replacement project, CIP 650354-100000. Andover Associates will provide Preliminary Design Services (Step 1), Detailed Design and Bidding Services (Step 2), and Services During Construction (Step 3) during this contract.
Two future renewals are anticipated. The scope of work for this project generally includes replacing the PVC pipe and post aeration diffusers. Due to age and exposure to UV, this equipment is failing and is no longer supported by the original equipment manufacturer. This project will also provide a comprehensive analysis of the post aeration system as a whole, including blowers, provide a structural analysis of the former mixing pads over the chlorination tanks, and provide an analysis and solution to issues with the effluent sample pump.
2. PROCUREMENT: The Division advertised for a Request for Proposals (RFP’s) for the subject services on the City’s Vendor Services website and in the City Bulletin in accordance with the overall provisions of Section 329 of the Columbus City Code. The Division of Sewerage and Drainage received five (5) proposals on May 11, 2018 from the following companies:

6. ECONOMIC IMPACT: The SWWTP post aeration process provides dissolved oxygen to the treated wastewater in order to meet the daily minimum dissolved oxygen requirement of 7.0 mg/L set forth in the Plant’s NPDES (National Pollution Discharge Elimination System) permit. As the post aeration diffuser legs fail, it becomes more likely that the plant will have a permit violation due to the lack of oxygen delivered to the treated wastewater. This project will replace all of the post aeration diffusers and piping to ensure that the Plant’s permit is not violated.
7. FISCAL IMPACT: This ordinance authorizes the transfer within and the expenditure of $246,124.09 from the Sanitary Sewer General Obligation (G.O.) Bond Fund, Fund 6109, and amends the 2018 Capital Improvements Budget.
