Each Sunday I try to find an interesting chart or statistic about water to share. Honestly, I am really trying to make this water stuff interesting. This Sunday involves a pie chart, the Safe Drinking Act, and billions of dollars.
The Safe Drinking Water Act, as amended in 1996, established the Drinking Water State Revolving Fund (DWSRF) to make funds available to drinking water systems to finance infrastructure improvements. The EPA allots funds to each state based on the state’s proportional share of total eligible needs reported for the most recent Needs Survey.
The 2006 through 2009 allotments are based on the 2003 needs survey. This survey of over 53,000 community water systems and 21,400 not-for-profit non-community water systems indicated a 20-year capital investment need of $276.8 billion for public water systems.The pie chart below shows the percentages of each project type.
For example, the charts shows over the next 20 years, transmission and distribution projects represent the largest category of need at over $183.6 billion. 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” that includes such items as security needs.
