Greenville residents already had to conserve water and boil it before using it. Then on Sunday morning, many woke up and discovered they had little or no water pressure due to a water main break on Clinton Street.

"We didn't have any water at all this morning," said Gayle McGrath, bartender at the Majestic Grille on Main Street. When a cleaning person ran water to clean at 6 a.m., it came out of the faucet brown.

The break, which occurred either late Saturday night or early Sunday morning, is not related to an ongoing water crisis in town caused by a broken pump and a clogged filtration plant.

Dick Miller, Greenville Municipal Authority treasurer, said a 12-inch line that runs under railroad tracks about 300 yards from the authority's Clinton Street office broke. The cause of the break was unknown, but Miller said the aging pipe could have worn through. Parts of the water system are 50 years old, he said.

The water line may not be repaired until Tuesday, Miller said, adding that crews are working "around the clock" to fix it. The fact that the line is located under the railroad track creates additional problems, and crews will have remove the sidewalk to pull out the pipe, Miller said.

The break lowered water pressure for customers on the borough's east side early in the day. Miller said that problem has been resolved but "it could affect it again."

Miller said when a line breaks, it creates vacuums in the pipe that affects pressure. Customers farther away from the break, such as those in Hempfield Township will be more likely to have problems with water pressure, he said.

Residents and business owners have been dealing with the inconveniences of conserving and boiling water for about a week.

"It's been horrible," said Marc Rinella, owner of the Majestic Grille. Rinella, who has a well at home, said: "We've been bringing water in from home for coffee ... boiling the water, putting bleach in the water, using paper plates and plastic cups."

As for the authority's other problems, Miller said a temporary pump is working to keep water in the system.

"We think the system's functioning now with the rental pump. It can take care of the town's needs," he said.

Water boiling advisories remain in effect. Miller said the Department of Environmental Protection would not lift the advisories until the pump runs for 24 hours with no problems and samples collected test negative for contamination.

He said in a best case scenario, the boil water advisory could be lifted by Wednesday.
