Hurricane Sandy Pump and Treat Challenge

  • Hurricane Sandy Pump and Treat


Monster Storm Sandy slammed into the East Coast Monday October 29th, killing at least 16 people, hurling a record-breaking 13 ft. surge of seawater at New York City and knocking out power to more than 7.5 million across the East Coast.

The Verizon building in Manhattan was flooded. The 100,000 sq. ft., 80 ft. deep basement contained 40 ft. of sea water and an estimated 30,000 gallons of diesel fuel.


The contaminated water had to be removed and the diesel fuel separated from this toxic mixture.


Under extremely difficult conditions MERSINO pumped the mixture from the basement using ten 4 in. submersible pumps. For each pump, over 80 ft. of discharge hose was used to pump the water and diesel fuel to frac tanks. From these tanks, the Global Pump model 6GST, 6 by 6 in. standard trash auto prime pumps were used to pump the water (and fuel) to carbon water treatment vessels where the final treatment took place.

After the basement had been dewatered and the diesel fuel removed, MERSINO remained on site to maintain the sump systems while the under drains of the building's basement, which held an unknown amount of diesel fuel, were also pumped out and treated.


The customer is extremely happy with the quick response from MERSINO and how quickly we "pulled the water down." According to one manager, "this was one of the best group of people I have ever worked with, and that is due to the great attitude of the MERSINO crews."
