Irving, Texas, a city of about 255,000 people near Dallas, is growing fast, and its water supply and wastewater systems must be upgraded to support rapidly increasing demands. To do this, Irving has created a multi-year, citywide program to maintain and expand its water management systems. To learn more about this large-scale municipal infrastructure program, we talk with Walt Thomas, City Engineer for Irving. Walt earned a BS in civil engineering from Texas Tech University and an MS in Public Administration from the University of Texas.
