Infrastructure: the cracks are showing

Posted by: Aqua Blog Maven on July 7, 2008 at 7:09 am

From the Economist:

THE Mississippi River pushed relentlessly past dozens of levees this month. Towns were submerged, their buildings tiny islands in murky water. Ducks paddled on ponds that had once been farmland. Some flooding was inevitable, given the force of the swollen Mississippi. But a poorly managed flood-defence system did not help.

For the past few years it has been hard to ignore America’s crumbling infrastructure, from the devastating breach of New Orleans’s levees after Hurricane Katrina to the collapse of a big bridge in Minneapolis last summer. In 2005 the American Society of Civil Engineers estimated that $1.6 trillion was needed over five years to bring just the existing infrastructure into good repair. This does not account for future needs. By 2020 freight volumes are projected to be 70% greater than in 1998. By 2050 America’s population is expected to reach 420m, 50% more than in 2000. Much of this growth will take place in metropolitan areas, where the infrastructure is already run down.

If America does not act, says Robert Yaro of the Regional Plan Association (RPA), a body that plans for the New York-New Jersey-Connecticut region, it will have the infrastructure of a third-world country within a few decades. Economic growth will be constricted, and the quality of life will be diminished.

Water is not excluded from this:

America’s ageing water infrastructure is sorely underfunded: the Environmental Protection Agency forecasts an $11 billion annual gap in meeting costs over the next 20 years. One heavy storm can cause ageing urban sewerage systems to overflow. Last summer an 83-year-old pipe in Manhattan burst, sending a geyser of steam and debris into the air. Competition for water itself has become vicious. Georgia and Tennessee are in an all-out brawl over it.

“America 2050″ is an effort to address America’s aging water, energy, and transportation infrastructures. Michael Campana of Water Wired has a post about America 2050, with links to the prospectus and panel discussions. He will himself be sitting on a panelist discussion today regarding infrastructure issues. Check it all out from the Water Wired blog by clicking here.
