Global Environmental provided treatment services to support demolition of the former Southwest Detroit Hospital. Founded in 1974 after a merger of four neighborhood hospitals, the facility served Detroit’s Black community during an era of health care segregation and was the first hospital in the city to accredit Black physicians and nurses. Long abandoned, the site is now being transformed into the future home of Detroit City FC’s AlumniFi Field.

To enable safe basement access and inspection before demolition, Global mobilized a 200-gallon-per-minute treatment system capable of continuous, 24/7 operation. The system included a diesel-operated centrifugal pump, a BF-6 bag filter skid for coarse solids removal, and three LPV-5000 media vessels filled with TS8X30CPR reactivated granular activated carbon (GAC) to reduce contaminants of concern to below Great Lakes Water Authority (GLWA) discharge limits.

Global secured a special discharge permit from GLWA on behalf of the owner and managed all compliance monitoring and reporting. The system operated continuously for six days to complete initial dewatering before transitioning to intermittent operation for stormwater management. It was demobilized in September 2025 after the first phase of water removal was complete.

In November 2025, Global mobilized a new automated maintenance dewatering system to support ongoing demolition activities, working alongside Ideal Contracting. The system was designed for unattended operation, allowing demolition to proceed without interruption. A 2” submersible pump installed in the basement sump transferred water to a 21,000-gallon frac tank, where a 3” submersible pump conveyed water through a BF-4 bag filter skid, an MWT-2K2s carbon treatment system, and a loose LPV-2000 polish vessel before discharge to the sanitary sewer system.

A Global-built remote telemetry system relayed real-time operational data and logged permit-required flow information, reducing the need for daily site visits. Global staff conducted up to two site visits per week to perform maintenance and collect compliance samples. In December 2025, Global implemented a temporary winterization system to support reliable maintenance dewatering operations throughout the winter months.

By providing both initial high-volume dewatering and low-volume long-term automated treatment support, Global helped keep demolition moving safely, compliantly, and on schedule, clearing the way for redevelopment of a historic Detroit site into a new community anchor.
