FILE - In a May 14, 2016 file photo, water is flushed out from a hydrant, on the corner of Glenmore St. and Kentner St. in Corpus Christi, Texas. The Texas Gulf Coast city has issued three orders in less than a year telling residents to boil their water to ensure it's safe to consume, including a two-week order this month that sparked outrage, contributed to the city manager's resignation and renewed questions about how to fix the problem.
