Ash Excavation and Dewatering

Case Study

Ash Excavation and Dewatering

PROJECT

Ash Excavation and Dewatering

CLIENT

Fortune 250 Energy Client – Mid-Atlantic

SITUATION

The client’s east ash pond, located along the banks of the James River, was prone to flooding. In order to prevent coal ash from leaving the site during a flood event, they needed to excavate the ash to a higher north pond and close the lower basin to prevent future releases or spills.

SOLUTION

Glover was contracted to excavate approximately 1.6 million cubic yards of CCR material and move to an existing basin. Glover was responsible for surveying, clearing and grubbing, installation of erosion-control items, stormwater management, dewatering of the existing ash basin, ash excavation and hauling, placement and compaction of ash, as well as the installation of a structural pile wall and construction of a final cap.

OUTCOME

Glover successfully dewatered and removed ash from the east ash pond yo the north ash pond. The project was completed on time, and every deadline, even those that were not originally planned for, were met or exceeded. In addition, Glover dewatered more than 310 million gallons of contact water. At the time, that was an industry record for the most gallons pumped from an ash closure project.

Contract Value: $71 million
