14.4 MGD Pumping System Keeps Pipeline Project On Track

Strict DEP discharge requirements with high flow meets expectations

BACKGROUND

A pipeline company was pulling pipe from an offshore rig in the Atlantic Ocean to connect to a newly constructed metering station in the middle of winter. The pipe became stuck during the process and the pipeline company needed to excavate to a depth of 55-feet to reconnect the pipe and route it up to grade. Deep well dewatering was performed to reduce the water in the excavation and reduce hydrostatic pressure to make it safe for people to enter the cofferdam. Groundwater from the excavation had to meet discharge requirements in order for the project to stay on track.

OUTCOME
Rain for Rent provided a combination of 75 tanks, pumps, glycol heaters and spill containment to allow our customer to complete their work while meeting meet Department of Environmental Protection (DEP) discharge requirements while pumping at up to 10,000 GPM or 14.4 MGD.
