Waterbury water officials have fixed one water main problem but have found another larger problem in a 12-mile 80-year-old main.
Officials thought they had a fixed a leak over the weekend that was discovered on Nov. 16 but another leak sprung from a crack in a cast iron pipe on Sunday, forcing officials to close part of Thomaston Avenue between Huntingdon Avenue and West Main Street.
Workers have been releasing pressure from the pipe.
No water services have been affected, but city officials said Thomaston Avenue will stay closed because the part needed for the fix is being shipped from outside of the state.
If the pipe bursts, the city has emergency plans for water supplies for the fire department, downtown business district and Saint Mary's Hospital, which all get water from the affected main
