Developed by C-43 Water Management Builders for the South Florida Water Management District (SFWMD) and U.S. Army Corps of Engineers (USACE), the C-43 West Basin Storage Reservoir is a 170,000-acre-foot infrastructure project designed to store excess freshwater from the Caloosahatchee River, stabilize salinity levels, and prevent algal blooms. MC Squared provided critical laboratory management, construction materials testing, and quality control, ensuring compliance with USACE standards. Our contributions—including testing 22 million cubic yards of embankment, 110,000 tons of soil-cement armoring, and 19 miles of soil-bentonite cutoff wall—have helped ensure the reservoir’s durability, reliability, and long-term impact on Florida’s water resources and communities.
