HOUSTON – Houston’s aging infrastructure played a factor in the massive water line break in east Houston this week, according to Mayor Sylvester Turner. The 35-year-old water line that ruptured Thursday was still within the range of useability, Turner said. Before the water main break, the city sent a contractor to find and repair the leak, Turner said. While the contractors were on-site exploring the issue, the line burst when the soil around the line was moved. The advisory was lifted Saturday afternoon after the results from 43 water samples concluded that the was not contaminated during the water line break.
