1. BACKGROUND
This ordinance authorizes the Director of Public Utilities (DPU) to enter into a planned contract modification for professional engineering services with Hazen & Sawyer for the Residuals Management Plan Update, CIP #690540-100001, in an amount up to $500,000.00 for Division of Water Contract No. 2414.
Residuals are materials removed from water during the water treatment process. 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 water supply system. This contract is necessary to provide assistance to obtain turnkey beneficial use services of these water treatment residuals so the Division of Water (DOW) can continue to provide a long-term and reliable water supply to the Central Ohio area.
Work performed to date under the contract included assistance with developing procurement documents for turnkey dewatering services; evaluating the resulting proposals; developing contract documents for the turnkey services; contract negotiations with the turnkey vendor; and providing engineering services during construction of the dewatering facility. The work to be performed under this contract modification includes surveying and associated services to continue engineering services during construction; performing services for property splitting and assemblage for the McKinley Avenue Quarry (MAQ) dewatering facility; and obtaining a beneficial use permit for the water treatment residuals. These services are necessary to dewater, store, haul, and beneficially reuse water treatment residuals (WTR).
Planning Area is Citywide - 99.
