WWTP Denis St Pierre—Belle River

Due to the dense underground infrastructure and integration with new plant structures, the work required precise excavation, grading, and installation of process piping, structural foundations, and utility corridors. Schouten executed the underground and site works with careful coordination between civil, structural, and mechanical trades to ensure accurate alignment of piping systems, proper trench preparation, and engineered backfilling to support long-term plant operations. All work was completed within an active treatment plant environment, requiring strict safety controls and coordination with ongoing plant operations. Various auxiliary building were demolished to make way for excavation and new piping and services to support the new control plant
