About this file
This is a Multi-Disciplinary Facilities Assessment document prepared by Jacobs Consultants Inc. for the Great Lakes Water Authority (GLWA) concerning nine combined sewer overflow (CSO) facilities in Michigan. The assessment encompasses comprehensive evaluations of CSO facilities including Baby Creek, Belle Isle, Connor Creek, Hubbell-Southfield, Leib, Oakwood, Puritan-Fenkell, Seven Mile, and St. Aubin. The document, updated as of May 20, 2022, provides detailed facility descriptions, capital improvement recommendations, and 20-year capital outlay plans organized across six volumes. The assessment addresses common facility needs including disinfection system improvements, electrical upgrades, instrumentation and control system enhancements, structural evaluations, building roof replacements, safety improvements, and maintenance work order reviews. Each facility section includes assessments of screening, disinfection, odor control, flushing and dewatering, HVAC systems, electrical systems, instrumentation and control systems, site conditions, architectural elements, safety, and supporting infrastructure.
The project employs a coordinated approach integrating Asset Management Planning through a Scheduled Replacement Plan, Performance-Based Planning via the Facilities Assessment, and 20-Year Capital Improvement and Capital Outlay Planning. Alternative evaluation methodologies utilize Net Present Value analysis and benefit ratio assessments to determine optimal solutions for facility needs. Capital cost estimating covers both Capital Improvement Project costs and Scheduled Replacement Plan asset replacement costs across multiple categories. The document establishes a repeatable, defendable process that meshes asset condition data with identified facility needs to prioritize investments while considering available budgets, resources, and regulatory compliance requirements. The assessment provides standardized recommendations for equipment replacement and facility enhancements to improve operations and maintenance efficiency, enhance operator safety, and ensure compliance with NPDES permit requirements for discharge to receiving water bodies.
