ISG supported a long-operating industrial facility in its transition from municipal discharge to a fully independent wastewater treatment system. A feasibility study with cost modeling evaluated stand-alone treatment options and was followed by multidisciplinary design of the treatment facility and supporting infrastructure. The solution addressed complex site constraints, challenging soil conditions, and a rigorous permitting process to enable direct discharge to a critical waterway. Effluent reuse and recovered material optimization were incorporated to improve system efficiency, operational resilience, and long-term sustainability.
