OVIEDO, Fla. — The water supply for residents and businesses in the Isles of Oviedo and the Oviedo Mall has temporarily been changed, and a precautionary boil water notice has been issued after a water mainline was struck on Aloma Avenue near Lutheran Haven Church, the city and Seminole County announced.

The water supply in that area is temporarily changed from Seminole County to the West Mitchell Hammock Water Treatment Plant, the city of Oviedo said in an alert on its website. 

Service was interrupted in the area Wednesday after the mainline was struck, and Seminole County Field Operations crews worked to repair the mainline. 

The complete loss of water pressure sparked the precautionary boil water notice. The alert covers the areas of Red Bug Road from Slavia Road to Aloma Avenue and Aloma Avenue from Red Bug to Slavia Road.

Officials say as a precaution, they advise:

• All water used for drinking, cooking, making ice, brushing teeth, or washing dishes be boiled
• A rolling boil of one minute is sufficient
• Bottled water may be used as an alternative

The city said the West Mitchell Hammock Water Treatment Plant uses a different disinfection process than Seminole County so customers could notice a change in the chlorine taste and smell in their drinking water. The change in water treatment and in the direction of the water flow in the distribution system could also cause a temporary change in the color or appearance of the water, officials said.  If it doesn’t clear after running a cold and a hot water tap for 15 to 20 minutes, customers can call 407-971-5692 between 7 a.m. and 3:30 p.m. After 3:30 p.m. nights and weekends, customers can call 407-971-5675.

The water is safe to drink, officials said.

For customers using dialysis machines or aquariums, any disinfectant used by water treatment plants needs to be removed or neutralized from the water for use.

All traces of chloramines must be removed from the water used in dialysis machines. Contact your physician or kidney dialysis center for information and proper procedures.

To condition tap water for use in aquariums, fish owners should use products recommended for neutralizing chloramines. Contact your local pet store for the appropriate water treatment for drinking water containing chloramines.
