Efforts are made to notify all affected customers of unexpected water main breaks or excessive pressure drops as soon as possible.  The public is notified one working day in advance of scheduled interruptions.

A boil order is issued, as required by the Illinois Environmental Protection Agency (IEPA), when any work results in an interruption of service, or causes water pressure to drop below 20 pounds per square inch.  Notification is made to city offices, the Madison County Health Department, and the IEPA office in Collinsville.  Notification lifting the order is made to the same offices.  

A boil order remains in effect until test results from the lab indicate the water is safe, typically 48 hours.
