In the United States, billions upon billions of gallons of stormwater are transported through the local sewer systems every day. The pipes that the water travels through have different degrees of structural integrity. Some of the pipes are as small as 8 inches in diameter and some are as large as 120 inches. The storm sewers can be made out of brick, metal, concrete, clay and plastic. As communities grow and these sewer systems age, local governments are forced to incur costs far beyond the material and labor to rehabilitate or expand the pipelines. Government officials must also figure out how to alleviate traffic delays, as well as business interruptions and disruption to neighborhoods, which can add to the cost of repairing the stormwater system.
