Construction season usually means water system construction, and sometimes there may occur the need for a precautionary boil order. A precautionary boil order indicates an incident or action that has caused the water system to become susceptible to outside contaminants. If necessary, the Village will notify the affected area to take precautions for a period of time while water samples are collected and tested by a state laboratory. These precautions include: not using tap water for consumption, cooking, cleaning foods, or brushing your teeth, unless boiled and cooled first. Residents should only use bottled water or boiled water during this time. Boiled water must reach a rolling boil for 5 minutes, and then cooled.
A precautionary boil order can occur when there are maintenance needs on the water system. These may include water main breaks, fire hydrant replacements, service leaks, or new construction projects. State Regulations require the issuance of precautionary boil orders when the pressure drops below 20 pounds per square inch (PSI) in the distribution system. It is possible but unlikely that bacteria may enter the water system during these low-pressure circumstances. The duration of each precautionary boil order is different. Sample results can take anywhere between 24-48 hours, but once samples pass, the boil order can be lifted. A “green” notice will be taped to your front door, letting you know the boil order is lifted.
How will the affected area be notified of a precautionary boil order? When a task is preplanned, notification of the work and area affected will receive letters on your front door at least 24 hours in advance of the scheduled work. In the event of a water main break or an emergency, Public Works staff may need to shut down the water prior to notification. Once safe to do so, the Village will post notices taped to front doors in the affected area.
