Highlights
Sand Island WWTP is a water and wastewater infrastructure project in Honolulu, HI. Sand Island WWTP is the City and County of Honolulu's largest wastewater treatment facility and serves the East Mamala Bay basin. Pacific Foundation supported the Sand Island Wastewater Treatment Plant work with CFA piles and a value-engineered design-build CDSM system for the IPS excavation, utility trenches, and tower-crane foundations. The scope used 96-inch CDSM columns, soldier piles, tiedown anchors, and additional ground-stabilization columns to form the bottom seal, perimeter shoring, and trench support for wastewater-plant construction.
