For many years, the City of Grand Prairie Streets and Water Utility Division has removed concrete from areas of the community during routine maintenance activities and have brought the debris to the landfill. Much of the concrete comes to the facility mixed with soil. Though the landfill is been able to keep pace with grinding material deposited annually, there is a 30,000 cubic yard “legacy” stockpile of dirt and concrete still to be addressed. Further, the amount of dirt currently contaminating the stockpile prevents it from meeting the specifications required by the Streets Division for many of its projects. For that reason, the Streets Division has only purchased 30% of their flex-base from the solid waste division over the past three years.
A high energy screen plant will allow landfill staff to sift dirt and contaminants out of the concrete stockpile prior to grinding allowing a purer end-product.
