Infrastructure

Infrastructure projects include transportation networks with roads and bridges and transit such as rail; telecommunications; dams; energy transmission lines and pipelines; treatment facilities and piping for collection and treatment of wastewater and stormwater; treatment and distribution of water; and solid and hazardous waste disposal facilities. We all depend on infrastructure and it makes our daily lives much easier. Our infrastructure in the United States needs continual repair, maintenance, replacement and expansion to meet new environmental regulations and growing demands from the public use. The American Society of Civil Engineers 2009 Report Card for American Infrastructure gave mediocre or poor grades for 15 different types of infrastructure. (http://apps.asce.org/reportcard/2009/grades.cfm)
