Explanation
1. BACKGROUND:
A. Need. This legislation authorizes the Director of Public Utilities to enter into a construction contract with Siemens Water Technologies Corporation, for the Jackson Pike Wastewater Treatment Plant Digester Cover Rehabilitation project for the Division of Sewerage and Drainage. These digester covers are part of the biogas (methane) handling system at the wastewater treatment plant. This is the first phase of a three-year program to rehabilitate five covers and six control systems. Five of the existing Dystor digester covers are near the end of their useful lives and are beginning to experience leakage of flammable biogas. The leaks now render the systems inoperable as designed. These improvements are necessary to provide reliability and continued operational performance for this vital treatment process.
The proposed construction contract with Siemens Water Technologies Corporation is for Contract J213. This contract work consists of replacing the Dystor air and gas membrane covers and the Dystor digester cover control systems, rehabilitating the concrete structures and gas wells for Digesters Nos. 1 and 2, along with providing training for the plant personnel to operate the new control systems. The identical work will be performed on Digesters Nos. 5 and 6 in 2009 and on Digester No. 4 in 2010. This continued work shall be funded by new contracts, negotiated and funded by appropriation in the identified years.
This ordinance is being submitted in accordance with the provisions of Sole Source procurement of the Columbus City Code Section 329.07. The Division of Sewerage and Drainage originally purchased the digester cover equipment at the Jackson Pike Wastewater Treatment Plant through competitive bids. The award was made to Siemens Water Technologies Corporation, who is the sole manufacturer and distributor for the Dystor digester cover equipment.
