Bill Rethlake | Daily News GREENSBURG — A ruptured water main near the old water treatment plant in the 1100 block of N. Ireland Street prompted local officials to issue a Boil Water Advisory late Monday morning. The main break took place at approximately 9:30 a.m. and the advisory was issued about an hour later. The problem resulted in Greensburg and North Decatur schools being dismissed at 1 p.m., and several local factories and businesses also had no choice but to send people home early.
