Original equipment for the headworks grit removal system at Belle Glade’s wastewater treatment plant had fallen into disrepair and was no longer operational. Globaltech was selected as a design-build company to evaluate different upgrade options and provide design, construction and commissioning services.
The existing system was comprised of two grit removal trains utilizing the Jones+Attwood Jeta Grit Removal system, including circular grit chambers, paddle-wheel mechanisms, air-lift grit pumps, grit classifiers, and grit dumpsters.
Work under this contract was administered by Palm Beach County Housing and Community Development and followed the requirements of the Davis-Bacon Fair Labor Act.
