Location: Barceloneta, Puerto Rico

Description: This project consisted of twelve (12) drilled shafts to be used as wells to inject storm water back into the local aquifer; plus one (1) dedicated as a vent shaft. All wells installed inside a pit several feet below ground level where storm water was collected from overflowing holding ponds. Shafts were drilled dry with 30 inches in diameter and depths of up to 130 feet. A slotted PVC pipe was installed and encapsulated in pea gravel to allow water flow. The top was cover with several layers of different size gravel and a geo-synthetic fabric to prevent fines from reaching injection wells.
