Dehumidification Aids Water Tank Rehabilitation

When Long Island American water Corporation targeted its 2.5-million-gallon water tank for maintenance, the owner scheduled the work over the winter and spring months so that the tank could be put back into service by May 1, 2005, says Rich Kern, PE, project engineer for the company. Working in the cold, wet winter months necessitated the use of dehumidification equipment, as well as heating equipment, to keep relative humidity levels and steel temperatures suitable for surface preparation and coating operations, says Sam Scaturro, operations manager for Alpine Painting and Sandblasting Contractors.
