Probe: New Orleans flood control pumps not reliable
WASHINGTON — Huge flood-control pumps installed in New Orleans after Hurricane Katrina don’t protect the city adequately and the Army Corps of Engineers could have saved $430 million in replacement costs by buying proven equipment, a federal investigation finds.
The investigation by the federal Office of Special Counsel finds there was “little logical justification” for the corps’ decision to spend hundreds of millions of dollars on the “untested” hydraulic pumps, which are meant to empty millions of gallons of water from the below-sea-level city during storm-related floods.
Citing the corps’ $430 million plan to replace the hydraulic pumps by 2012, just five years after they were installed, the special counsel concludes that a “proven” direct-drive pump design would have been less prone to corrosion and breakdowns. Based on an independent engineering review, the counsel says direct-drive pumps could have been purchased “more quickly, more reliably and without planning for pump … replacement.”
Hydraulic pumps are powered by pressurized oil. Direct-drive pumps use solid drive shafts.
The findings, previously unreported, were sent to President Obama on June 12.
