DIMP-Related Pipe Replacement Work Continues in Full Force US
Pipeline & Gas Journal staff report While the amount of work to replace cast-iron and bare-steel pipe has declined in volume since the implementation of the Gas Distribution Integrity Management Program (DIMP) in 2009, there is still plenty of construction left to be done. The federal Department of Transportation (DOT) estimated that at the end of 2019, 21,771 miles (35,037 km) of cast-iron and wrought-iron pipelines were still in service in the United States. The majority of that is in older eastern cities, such as New York, Boston, Washington, D.C., and Philadelphia. This represents quite a headway since 2015, when there were 3,342 miles
