ASCE released its Infrastructure Report Card a few weeks ago. Wastewater improved slightly, from a D- in 2009 to a D this year.
"Capital investment needs for the nation's wastewater and stormwater systems are estimated to total $298 billion over the next twenty years," according to the Report's web site. Stormwater is a relatively small, though increasing, piece of the spending, but included in the wastewater section.
The largest percentage of the "need" is for expanding and fixing pipes in order to address sanitary sewer overflows and combined sewer overflows.
From the report:
"In 2008, EPA reported that the U.S. 20-year investment needs for aging
wastewater treatment totaled just over $298 billion, or almost $15
billion annually. The total represented a 17% increase over the 2004 Clean Watershed Needs Survey (CWNS) results.
Meanwhile, annual appropriations for the Clean Water State Revolving
Fund (CWSRF) totaled $9 billion over the five years from 2008 to 2012,
an average of slightly more than $1.8 billion annually, well short of
the annual need. Congressional appropriations totaled approximately
$10.5 billion between 2008 and 2012—about $2.1 billion annually or $42
billion over 20 years, 14% of the 20-year needs.
"Of the total needs, over $202 billion in the CWNS was the nationwide
capital investment needed to control wastewater pollution for up to a
20-year period. The 2008 report included estimates of $134 billion for
wastewater treatment and collection systems, $55 billion for combined
sewer overflow corrections, and $9 billion for storm-water management."
