A mandatory boil water alert has been issued for all residents of Hollywood and some of its customers who live outside the city's limits.
The alert is effective immediately.
Areas of Pembroke Pines, Miramar and Dania Beach that get their water from Hollywood are affected by the alert.
In Hollywood, the city's water treatment plant experienced a significant drop in pressure, below 20 pounds per square inch, which is an indication of a significant water main break, a media release said.
The city is now advising all property owners to boil their water for drinking purposes until further notice.
"Residents should not use the water without boiling it first, as boiling kills bacteria and other organisms in the water," a media release said.
The city recommends that residents bring all water to a boil and let it continue boiling for one minute before using it. It's also recommended to disinfectant water by adding eight drops of plain unscented bleach per gallon of water and let it stand for 30 minutes before drinking it.
If the water remains cloudy after 30 minutes, repeat the procedure.
For the time being only boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation.
Hollywood and Broward County will advise when the order has been lifted.
