HIGHLANDS RANCH, Colo. -- November 14, 2012

ARCADIS (EURONEXT: ARCAD), the international design, consulting, engineering
and management services company, was the inaugural recipient of the IWA
Executive Director Prize for Impact at Scale award during the bi-annual
Project Innovation Awards for their work on the U.S. Army Corps of Engineers’
(USACE) Greater New Orleans Hurricane and Storm Damage Risk Reduction System
(HSDRRS). The award was presented earlier this fall at the IWA’s World Water
Congress held in Busan, South Korea.

ARCADIS worked as part of a joint venture on components of the USACE’s HSDRRS
to reduce risk to areas of New Orleans and surrounding parishes hard-hit in
2005 by Hurricane Katrina, from future storm events. One of the highest
profile components of the HSDRRS was the West Closure Complex Pump Station, a
facility with 11 specially designed pumps each powered by a 5,000 HP diesel
engine each weighing over 70 tons. The enormous size and complexity of the
pump station required unique design and fabrication. The volume of water moved
by one of these pumps could fill an Olympic-sized swimming pool in less than
five seconds, providing a significant first-line of defense from hurricane
storm surge for the more than 250,000 residents and industrial businesses
along the Harvey and Algiers canals.

Bill Dee, director of the Global Water Business Line, said: “We are incredibly
honored to receive this level of recognition from the International Water
Association. The team in New Orleans worked diligently to complete these
projects on time, and when Hurricane Isaac battered the Gulf Coast, we saw the
risk reduction systems in action, performing as engineered to provide a first
line of defense for the city of New Orleans.”

Other major components of the USACE’s HSDRRS include the Inner Harbor
Navigation Canal (IHNC) Seabrook Sector Gate Complex, a 95-foot-wide navigable
sector gate and two 50-foot vertical lift gates used for flow control; the
IHNC Lake Borgne Surge Barrer, a 1.8-mile-long barrier that will reduce storm
surge from the Gulf of Mexico from flooding Orleans and St. Bernard parishes;
the Lake Pontchartrain and Vicinity Bayou Dupre Control Structure, a
43.5-foot-tall, 56-foot-wide sector gate; and 23-miles of levees and floodwall
in St. Bernard’s Parish together with a closure gate system.
