state and local.

The needs of local and state government are unique, and require a vendor that understands this environment. Tasked with significant responsibilities in public safety and other areas, but without the level of funding that federal entities can rely upon, state and local governments must be creative and efficient. SDI has worked with local and state governments at every level for over 18 years, so we understand this environment and what it takes to be successful. That is why some of the country's largest local and state governments trust SDI to implement and support their mission-critical systems. SDI's notable recent clients include the following:

• Nation's largest CONVENTION CENTER
  
• One of the nation’s largest TOLLWAY SYSTEMS
  
• Largest city AVIATION AUTHORITY in the US
  
• Largest WATER PURIFICATION PLANT in the world
  
• 2nd busiest AIRPORT in the world
