SHARON – Sometime around 1 a.m., Sharon resident Tim Christy heard the rain.

Then Christy remembered — it wasn’t raining.

“I realized it wasn’t rain. But I knew it was lots of water,’’ he said.

Christy, who lives with his mother on South Irvine Avenue near A Street, opened the home’s front door and was dumbfounded by what he saw on the street.

“The whole road was covered with water,’’ he said. “It looked like a river.’’

Christy and scores of other neighbors along the same corridor were awakened about the same time by the thundering noise of rushing water caused by Aqua Pennsylvania’s ruptured water main break on A Street.

“I was just in shock,’’ said Crystal Norcross, Christy’s mother.

Rushing water from a ruptured 12-inch water main, owned by Aqua Pennsylvania Water, obliterated about 75 linear yards of A Street, located on Sharon’s West Hill.

Flood waters reached as far as the Sharon municipal building and across the street at the Sharon City Centre plaza, said city Manager Bob Fiscus.

“We had about two feet of water in back of the city building that seeped into the garage where we keep the fire trucks,’’ Fiscus said. “There was a minimal amount of water that came in. But if we had opened the large garage doors a large wave of water would have rushed through.’’

A technician is testing the city’s heating and air conditioning system to ensure it wasn’t damaged, he said.

Firefighters spent much of the day squeegeeing water out of the garage, Fiscus added.

No business or homeowner had reported any significant damage, Fiscus said.

But the ruptured water main took a toll elsewhere.

“A sanitary line was wiped out and storm lines are broken,’’ Fiscus said. “Aqua understands these need to be replaced. They’ve been great partners with us.’’

The water main break is likely due to age, said said Donna Alston, an Aqua spokeswoman.

“It dates back to the 1920’s,’’ she said. “That’s why we are replacing so many of our older lines.”

The water main break left about 25 Aqua customers without water but service was restored around 10:30 a.m. Friday, Alston said. Sharon customers went back to full service, without a boil-water advisory.

Customers along Yankee Run Road and Lincoln Street in the Masury section of Brookfield were subject to a boil-water advisory issued Thursday and lifted about 3:30 p.m. Friday. The advisory did not affect Sharon residents.

Repairs to the area continued Friday with temporary paving to A Street expected this weekend.
