Underwater Construction Corporation (UCC) provides comprehensive operational and maintenance services for the removal and disposal of invasive zebra and quagga mussels. Its expertise includes removal from power plant and industrial cooling water intake structures, along with raw water screens for drinking water plants.
In addition to the diver removal, dewatering, euthanasia, and disposal of these invasive mussels, UCC has deployed preventative technologies to discourage the establishment of damaging zebra and quagga mussel colonies on critical marine infrastructure. These projects involved the installation of chlorine and biocide/molluscicide chemical dosing lines at the raw water intakes structures.
UCC provides commercial diving services to perform the cleaning and inspection of raw water intake and discharge infrastructure. Typically, this starts as an initial inspection, documenting mussel growth and infestation. This data determines preventive maintenance schedules.
UCC’s divers use various methods and tooling to remove mussels from the structures, pipelines, tunnels, components, water intake forebays and other infrastructure. Diver-assisted dredging is performed to remove the mussels to the approved disposal areas.
Following cleaning, a follow-up assessment documents the cleaned infrastructure condition. UCC provides the client a compressive report and video as final deliverables.
To process diver-hand-dredged zebra mussel shells and sediment, Underwater Mineral Processing Services (a division of UCC, https://mpsmaine.com/) installs and operates hydraulic conveyance of the mussels and sediment to land.
