Officials in London say a water main break at the main plant disrupted service across the city for most of Wednesday.
The break was reported around 3 a.m. on Wednesday, and the city began losing water pressure around 7 a.m.
More than 9,000 city customers were without water until water was restored shortly before 7 p.m.
Resident Jonathan Clevenger said he was glad to have water back Wednesday evening, even though it was just trickling. Officials said the pressure should continue to improve.
"Yeah, it's really nice," he said. "It's better than nothing."
Repair crews worked to repair the 10-inch-line, which goes into a 14-inch line.
The age of the line may have caused it to break, according to the water department.
The line was put in when the plant was built and is around 50 years old.
Gas crews were also called in to check out a gas line that runs in the area.
The city is currently under a two-week boil advisory.
According to a letter issued by the City of London on Wednesday afternoon, residents are asked not to drink or serve water without boiling it first. The boil advisory will be in effect until further notice.
The Presbyterian Child Center said health officials asked them to remain closed since there is still some health risk.
The center said they care for around 125 kids each day, and workers had been notifying parents to make alternate arrangements.
"I mean that's a burden for them," said Anna Harpold, who works at the center. "And that's hard for us to see them have to do that."
For the next two weeks, residents also are asked to limit use of water to necessary activities.
The health department closed all the restaurants in town on Wednesday.
The Madison County Senior Center was closed due to the water outage.
Fire departments are using cisterns until water pressure is restored.
Those at the Madison County Hospital made an emergency call to have a water tanker haul as much water as it could to pump it into the hospital line to keep the hospital running.
"We have gallons of water in patient rooms for washing and bathing, so right now, everything is falling into place," said Jennifer Piccione of the Madison County Hospital
For patients who require specialized meals, the hospital said it has enough pre-made meals to get by.
The hospital said that all of the years planning for mass disasters were paying off.
"You always think this day will never happen, and it happens, and it's a great test," Piccione said.
The American Red Cross is assisting those who've been impacted by the water main break in Madison County.
The organization will be delivering 72 cases of water to the London Senior Center which will reopen Thursday morning.
Resident Dennis Smith said that he had no choice but to stock up for water.
"I had a swimming pool in my back yard and took the water out of the swimming pool, so I could shave," said Smith. Resident Kelly Barnhart said that she is miserable.
"You can't do dishes, can't do anything, can't take showers, it's pretty bad," she said.
Officials said the water main break caused a loss of more than 600,000 gallons of water.
