From the fact sheet:
…The survey estimated a total national infrastructure need of $384.2 billion for the 20-year period from January 2011 through December 2030. American Indian and Alaska Native Village systems represent $3.3 billion of the total national need. It is important to note that the scope of the survey is limited to those needs eligible to receive DWSRF assistance – thus excluding capital projects related primarily to dams, raw water reservoirs, future growth, and fire protection….With $247.5 billion in needs over the next 20 years, transmission and distribution projects represent the largest category of need. This result is consistent with the fact that transmission and distribution mains account for most of the nation’s water infrastructure. The other categories, in descending order of need are: treatment, storage, source, and a miscellaneous category of needs called “other.”…The results of the state survey show that the nation’s medium-sized community water systems (serving between 3,301 and 100,000 people) account for the greatest share, 43 percent or $161.8 billion, of the total national state system need. Large and small systems also have substantial needs of $145.1 billion and $64.5 billion, respectively….
