Marine Construction & Environmental Remediation – Galesburg (2016)

Walsh Service Solutions leadership managed a massive, high-complexity environmental dredging and water treatment operation along the Kalamazoo River watershed. This private contract required the design and execution of a full-scale industrial treatment infrastructure to manage impacted sediments and massive volumes of process water under strict environmental mandates.

Project Overview

  • Project Value: $42M

  • Timeline: 2016

  • Location: Galesburg, Michigan

  • Key Metrics: 90,000 CY of impacted material | 185 million gallons of water treated

Project Scope & Operations

  • Complex Dredging Operations: Deployed five 8” hydraulic suction cutterhead dredges to perform precision extraction of impacted material from specifically engineered polygons to prescribed depths.

  • Large-Scale Conveyance System: Designed and constructed a 44,000 linear foot (LF) HDPE pipeline system to transport dredge slurry from the river to the upland treatment facility.

  • Upland Dewatering & Treatment: Engineered and operated a custom dewatering pad and a sophisticated water treatment plant capable of processing 185 million gallons of water to meet discharge standards.

  • TSDF Logistics: Managed the stabilization and transport of 90,000 cubic yards of treated sediment to a Treatment, Storage, and Disposal Facility (TSDF) for final certified disposal.

  • Strategic Management: Project leadership oversaw the integration of mechanical and hydraulic dredging methods to ensure 100% removal efficiency of targeted environmental contaminants.

The Result

This $42M effort stands as a benchmark for large-scale environmental restoration. By successfully treating nearly 200 million gallons of water and safely disposing of 90,000 cubic yards of impacted sediment, the management team restored the local ecosystem’s health while maintaining a rigorous production schedule and total regulatory compliance.
