People in the affected area should take the following precautions:

DO NOT DRINK THE WATER WITHOUT FLUSHING AND BOILING IT FIRST. Flush all taps used for drinking and cooking for at least 3 minutes. Bring all water to a boil, let it boil for at least one minute, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice. Boiling kills bacteria and other organisms in the water.

Waterborne illness may include nausea and stomach discomfort. If you experience one or more of these symptoms and they persist, contact your doctor. People with severely compromised immune systems, infants, and some elderly people may be at increased risk. These people should seek advice about drinking water from their health care providers.

Cleveland Water has no evidence at this time that the water system is contaminated. The possibility, however, does exist that the water system is contaminated and is issuing this advisory as a precaution.

Additional Water Quality Advisory

This 54-inch water main break on Highland Road is on a water main not used for direct service to customers. However, it may also cause additional disruptions in water quality including discolored water and/or potentially a temporary increase in lead levels in the drinking water. As a precaution, you may wish to use a water filter certified to remove lead to temporarily filter your water used for drinking, cooking and brushing your teeth. Manufacturer’s instructions on how to properly use the filter, including when the filter should be changed, are included with the filter and should be read prior to use.

As a standard practice the USEPA recommends the following actions to reduce possible lead exposure in drinking water:

  • If water has not been used for several hours, run the tap until there is a noticeable temperature drop. Then, run water for 30 seconds to 3 minutes before using it for drinking and cooking. This helps flush water that may have contained lead that may have leached from plumbing.
  • Use cold water for cooking, drinking, and preparing baby formula. Boiling the water will not reduce lead.
  • Clean your faucet aerator regularly.
