Customers of North Choctaw Water Authority have had problems for several days with their water service.
It's attributed to sub-freezing temperatures in the past week.
An official says the most recent problem is a main line in Yantley that broke Saturday.
An additional crew was added Monday to try to get the repair finished by Monday or Tuesday morning.
North Choctaw serves about 3,500 people.
Customers in the Dalewood and Toomsuba areas of Lauderdale County have also reported they have been without water service for several days.
Toomsuba Water System says it has been working around the clock to thaw frozen filter banks in the treatment plant. It reported Tuesday that progress is being made.
However, TWS says until the plant thaws, residents are encouraged to conserve as much water as possible.
TWS has also issued a boil water notice for all customers, effective through Jan. 25, because of the problems. That applies to those who have their water service back now and for others when it is restored.
"We just got the third well up this morning, well about one 1:00, and we're trying to get the tanks filled back up so we'll have some pressure," said Billy Barrett of Toomsuba Water Association Tuesday afternoon.
TWS said all questions should be directed to 601-632-4366. The time frame for all customers being restored is unknown but TWS is offering a free case of bottled water to its customers who are affected.
