Anomaly Dig

Scope

Michels Construction, Inc. and Michels Pipeline, Inc. teamed up to isolate standing water and control groundwater in permeable soils to allow a pipeline joint to be repaired. The dewatering crew first installed 12 portable dams and then installed a wellpoint dewatering system to control groundwater while the pipeline construction crew completed the work. The entire project was completed in 11 days.

  • Michels dewatering and pipeline construction operations teamed up to isolate standing water and control groundwater in permeable soils to allow a pipeline joint to be repaired.
