Boil Water Advisories
If you are under a Boil Water Notice as a precaution, we advise that all water used for drinking, cooking, making ice, brushing teeth, or washing dishes be boiled. A rolling boil of one minute is sufficient. As an alternative bottled water may be used. This "Precautionary Boil Water Notice" will remain in effect until the problem has been corrected and bacteriological survey shows that the water is safe to drink.
If you have any questions you may contact Seminole County Utilities Department at 407-665-2110. Additional information will be made available on the Utilities Department website.
