In 2013, The Washington Post reported that the Washington Suburban Sanitary Commission (WSSC), which serves 1.8 million people in two Maryland counties, had 350 miles (560 km) of prestressed concrete cylinder pipe in use as water mains (Shaver, 2013b). These large but relatively unreliable water mains (with diameters as large as eight feet) carry pressurized water, and nine exploded between 1996 and 2013. One explosion led to flooding on a major road, and another blew out doors and walls in an office park. Due to laws restricting the release of information about critical infrastructure, WSSC has not released information about the locations of these mains. Assume that you live in the WSSC service area. What risks do these mains pose to you? What options do you have for managing these risks?
