Solicitation # sioux-city-wastewater-treatment-plant-facility-plan-phase-1-improvements-project
The Sioux City Wastewater Treatment Plant Facility Plan Phase 1 Improvements Project, managed by Rice Lake Construction Group, involves extensive upgrades and rehabilitations to critical plant infrastructure in Iowa. Key mechanical and process improvements include the replacement of preliminary treatment equipment, primary clarifiers, and the RAS pump station, alongside the conversion of aeration tanks to a three-stage process and the rehabilitation of an anaerobic digester for sludge storage. The project also prioritizes safety and operational reliability through the installation of new standby emergency power generators, main switchgear replacement, SCADA system upgrades, and plant-wide odor control measures to mitigate emissions from headworks and dewatering areas. The scope of work encompasses significant demolition of unused structures and buildings, complemented by comprehensive site and civil improvements. Required materials and services span a wide array of disciplines, including hazardous material abatement, concrete and masonry work, HVAC, electrical systems, and specialized water and wastewater equipment. This large-scale modernization effort integrates structural rehabilitation with advanced process gas and liquid handling systems to ensure compliance with NFPA 820 and other safety standards.
