Tomahawk Creek Wastewater Treatment Facility Process Improvements Project

The project involves improvements to the Tomahawk Creek Wastewater Treatment Facility, including odor control improvements, sidestream nitrogen treatment improvements, gravity thickener H2S reduction, co-thickening improvements, and other modifications. The project requires the installation of new equipment, modification of existing equipment, and construction of new structures. The contractor will be responsible for ensuring that all work is completed in accordance with the plans and specifications provided. Some key features of the project include: • Installation of covers on the BNR Basin anaerobic and pre-anoxic basins • Addition of Odor Control System No. 4 • Customized rubber mat covers for the BNR Influent Splitter Box and RAS Splitter boxes • Separation of centrifuge startup/shutdown slop flows from the main centrate discharges • Addition of ferric chloride feed capability to the Primary Sludge Gravity Thickener/Fermenter • Modifications to allow thickened primary sludge to discharge directly to the Co-Thickened Sludge wetwell • Installation of pressure sensors on digester feed pump discharge piping with SCADA integration • Construction of an access drive and installation of cleanouts for scum pit drainpipes • Addition of electric actuators to six PC Influent Slide Gates at the Headworks Building • Replacement of potable water with Plant Effluent Water as carrier water for Micro-C dosing • Rerouting of Micro-C discharge lines above grade for improved visibility and control The project requires a high level of technical expertise and experience in wastewater treatment facility construction and modification. The contractor will need to demonstrate a thorough understanding of the plans and specifications, as well as the ability to manage and coordinate the various aspects of the project. • Odor control improvements • Sidestream nitrogen treatment improvements • Gravity thickener H2S reduction • Co-thickening improvements • Construction of new structures • Installation of new equipment • Modification of existing equipment
