A construction company in San Diego needed to bore a hole under railroad tracks for a utility company to run wire underground, 15 ft below grade. The site location was a marine terminal, so Envent was contracted to dewater the area for digging and to treat the subsequent contaminated water. Savings of $24,000 and the successful discharge of 250,000 gallons of clean water.
