Boil Order Information
Information on Precautionary Boil Orders
From time to time, the Municipal Services Department must issue a boil order notice to residents and other water customers to ensure their health and safety. Under almost all circumstances, these orders are localized to a specific area and are a precautionary measure. However, in rare cases, a condition may arise which requires a larger boil order. Precautionary boil orders are meant to inform customers that there has been an incident that caused the water system to become more susceptible to outside contaminants. Precautionary boil orders do NOT mean water has tested positive for contamination. It is NOT the same thing as a mandatory boil order. Instead, it is a precautionary measure meant to empower customers to make the best choices for themselves, their families or their business customers until proper testing can be completed.
Below are some frequently asked questions regarding these boil orders for those customers who may be impacted:
1. What is a a precautionary boil order?
A precautionary boil order is most commonly issued when Village crews need to shut down a segment of water main due to an emergency water main break or other maintenance activity. IEPA rules and regulations call for the immediate issuance of a precautionary boil order for any emergency which results in water pressures falling below 20 pounds per square inch. When pressure falls below that amount, there is a possibility that microorganisms outside of the water pipe could infiltrate the water system and cause illness. A boil order is simply a notice that customers should boil their water being used for culinary or drinking purposes for five minutes prior to use in order to prevent possible exposure. In almost all cases, water can be used for other purposes (such as bathing, washing clothes or gardening) without the need for to boil the water.
2. Why is a boil order issued?
The most common reason is that sustained pressure in a water main fell below 20 psi. These are designed to give customers a precautionary notice about their water and the tools necessarily to continue to safely use water.
A larger order may be issued if the Village’s water system loses pressure, and Village staff is unable to verify system pressures adjacent to the event.
3. How long should I boil my water?
Water should be brought to a rolling boil for five minutes and allowed to cool before drinking.
4. How will customers be notified about a boil order?
For a localized or small-scale boil order, customers will be informed by personal contact from a Village employee, or a door hanger left on their front door. Should a wider area need to be notified, the Village will use the Village’s website, RAVE reverse 911, social media, and press releases to notify the impacted area.
5. How will customers be notified when a boil order is lifted?
If you received a door hanger for a precautionary boil order due to a nearby water main break, the boil order is in effect until 5pm the following business day. The Village will not provide any additional notification that the boil order has been lifted.
If a boil order was posted on the Village website or affects a larger area, notification will proceed in the same manner as the original notification.
6. What should I do following a boil order?
Customers may want to flush their home’s plumbing by letting a faucet flow, on the lowest level of the structure, for a few minutes. However, in most cases, as the order was precautionary, no special actions need to be taken. If additional steps are necessary, instructions will be issued with the notification to lift the boil order.
