Crews have spent days working to identify leaks, but city officials said pressure remains low or nonexistent.Selma, Alabama, was in the third day of trying to find leaks and started Monday to shut down major lines and interrupting service to try to isolate where the biggest leaks were happening, Mayor James Perkins Jr. said in a statement.Water crews in Florence, South Carolina, finally succeeded Tuesday in getting the water pressure back up after having to follow just about every water line in the city to find a large, but hidden, leak, officials said.“It’s not a great feeling, and we are sad because on Christmas, I woke up to make tamales and realized we had no water,” Maria Landeros, a 30-year-resident of Forest Park, told WXIA-TV in Spanish.“Most of the cause of that lack of pressure are the water leaks in privately owned buildings, particularly from fire-suppression equipment,” Memphis Mayor Jim Strickland said."
