Case Studies

As part of a multi-year bridge construction project over the Lehigh River in north central Pennsylvania, we created a dewatering system so foundation work could be done for the bridge piers. The environmentally friendly plan was engineered to control sediment when discharging water from the caisson. We designed the system with diesel generators, submersible pumps,...

FieldForce responded within hours to deploy four high-volume pumps and necessary layflat hose for a rapid response scenario to complete the dewatering of Philadelphia’s Vine Street Expressway, following the flooding caused by Hurricane Ida.

Response to East Palestine, OH train derailment On February 3, a Norfolk Southern train carrying toxic chemicals derailed in East Palestine, OH, a small community along a stream that feeds into the Ohio River. Fifty cars were involved in the derailment and subsequent fire. Out of concern for a potential explosion, on February 6, authorities...

We designed and engineered (including the hydraulic calculations) the entire system for an old mine pond dewatering application. Using an Atlas Copco pump we discharged a 10-15 million gallon pond 300 feet up the mountain and into an underground void. Included in the system were: One Atlas Copco PACH64, 275 HP high-head pump 3,200 feet...

We engineered a large diameter sewer bypass for a cured-in-place piping project (to re-line the sewer pipes) in a beach town in New Jersey. We ran 1,000 feet of 12-inch DR17 HDPE pipe, installed six road crossings at homeowner’s driveways, from a manhole in a backyard to the pump station. Included in the system were:...

For a bridge restoration project (erosion-related damage) in central Pennsylvania, we created a stream diversion so that concrete could        be poured under the bridge. We ran 200 feet of piping downstream    and discharged it into a dissipator to slow the discharge. Included in the system were: 12-inch corrugated hoses Two Atlas Copco PAC F1212 sound...
