Abstract: The water and wastewater infrastructure in the United States is failing. In its 2013 Report Card on American Infrastructure, ASCE stated: "The water and wastewater infrastructure is in poor to fair condition and mostly below standard, with many elements approaching the end of their service life. A large portion of the system exhibits significant deterioration. Condition and capacity are of significant concern with a strong risk of failure." Failures in water and wastewater pipeline infrastructure can have many impacts on the public, including disruption in water delivery, impediments to emergency response, water pollution, and damage to roadways and other types of infrastructure. Significant reinvestment is needed to replace, rehabilitate, and expand the pipeline network. In fact, the U.S. Environmental Protection Agency (EPA) estimates that approximately $632.8 billion of investment is needed for water and wastewater systems, with $281.6 billion (46 percent) specifically allocated for pipeline investment by 2028.
