HIGHLANDS RANCH, Colo. -- April 09, 2013

The American Society of Civil Engineers (ASCE) awarded their Outstanding Civil
Engineering Achievement Award (OCEA) to ARCADIS US, the subsidiary of ARCADIS
NV (EURONEXT: ARCAD), the leading pure play global engineering and consultancy
firm, for its Alvarado Water Treatment Plant Ozone Upgrade and Expansion
Project in San Diego. The project increased capacity at the 62 year old plant
by nearly 70 percent and improved the disinfection process providing safer,
better tasting water to San Diego’s growing communities.

The Alvarado Water Treatment Plant, the oldest active facility providing water
to San Diego residents, now uses ozone rather than chlorine to disinfect the
city’s drinking water. Ozone disinfection reduces the water’s level of
potentially harmful chlorine by-product and removes tastes and odors for
safer, more aesthetically pleasing water. The ozone process was placed between
settling and filtration, never before imagined in San Diego, and thereby
reduced chemical dosages and energy usage.

“This project, constructed in phases and affecting every facility on the site
over 12 years, showcases ARCADIS’ approach to applying innovative solutions in
concert with nature to our clients’ most challenging projects,” said Steve
Blake, CEO for ARCADIS US “We ensured the project didn’t disrupt local species
habitat, we employed sustainable design elements including the use of solar
panels, delivered the project on time and under budget, and the plant provided
the citizens of San Diego uninterrupted service that met all drinking water
regulations over the 12 year construction period.”

Established in 1960, ASCE’s OCEA Award recognizes a project and the many
engineers who have made a significant contribution to the civil engineering
profession.
