The Great Lakes Water Authority seeks a consultant to study, design, permit, and support construction of a diversion sewer connecting the Meldrum Sewer to the Conant-Mt. Elliott Sewer and Leib Screening and Disinfection Facility. The project also includes diversion and junction chambers, flow-monitoring equipment, and operational and control improvements for gates VR-15 and VR-16 and the Leib facility.

Additional services include asset management and document turnover, operations and maintenance procedures and training, State Revolving Fund application assistance, public involvement, property acquisition support, and pre- and post-construction flow monitoring, including an 18-month post-construction study. The solicitation requires relevant sewer and wastewater engineering experience, Michigan engineering licensure, three comparable projects completed within the past ten years, and submission of a proposed work plan, qualifications and references, cost information, and required vendor and diversity materials.
