 ** Please be sure to sign up to receive ENotification for alerts and notifications located at the bottom of the web site.

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.

During a boil water order, residential users should take the following measures to protect themselves from consuming potentially contaminated water:

1. Bottled water should be used for drinking, cooking, washing fresh fruits / vegetables, hand washing and tooth brushing.

2. The affected tap water can be used for these purposes but only after it has been brought to a rolling boil for 5 minutes.
3. The affected tap water may be used for washing dishes if a dishwasher is used. If dishes are hand washed, boiled or bottled water should be used. The affected tap water may be used if the clean dishes are immersed for at least one minute in a sink of water to which one full tablespoon of regular household bleach has been added.
4. The affected tap water may be used for bathing or showering.
5. The affected tap water may be used for household cleaning.

NOTE:  If the tap water is cloudy and / or contains particles, bottled water should be used. After the boil water order is lifted or water service resumes, these precautionary measures should be followed:

1. Flush the building’s water lines and clean faucet screens.
2. Purge the water-using fixtures and appliances of standing water and ice, such as refrigerator ice makers or coffee makers.



To continue operating under “boil water” orders or interrupted water service all retail food service establishments must secure and use potable water from an approved source (e.g., from tank trucks or bottled potable water) for all water usage.

This includes for the following uses:

1. Coffee, tea, and other beverages made in the food establishment
2. Ice
3. Washing produce or thawing frozen foods
4. Employee hand washing
5. Washing all dishes and cooking utensils
6. All water used in 3-compartment sinks
7. All water for sanitizing solutions It must be noted that equipment plumbed directly into the water system such as direct feed coffee urns, ice machines that manufacture ice on site, and post-mix soda or beverage machines may not be used during the boil order. If it is not possible to obtain potable water from tank trucks or bottled potable water and if a heat source is available, boil the water vigorously for 5 minutes.

After “boil water” order is lifted or water service resumes, these precautionary measures must be followed:

1. Run all water lines for one minute to flush contaminated water from system. This includes each fill point for post-mix soda and beverage machines.
2. Clean and sanitize all fixtures, sinks and equipment connected to water lines.
3. Run your dishwasher empty through three complete cycles to flush the water lines and assure that the dishwasher is cleaned internally before washing equipment and utensils in it.
4. Discard all ice in ice machines; clean and sanitize (1 table spoon of bleach per gallon of potable water) the interior surfaces; run the ice through 3 cycles; and discard ice with each cycle.
5. Replace all ice machine filters and beverage dispenser filters and flush all water lines for 10 to 15 minutes
