LOS ANGELES (KTLA)-

Cleanup operations continued Wednesday after a 93-year-old water main burst under Sunset Boulevard near UCLA, causing a massive flood that inundated several structures on the Westwood campus and prompted the closure of the busy thoroughfare.

Some 8 to 10 million gallons of water spilled out following the rupture, which occurred in the 10600 block of Sunset (map) shortly before 3:30 p.m. Tuesday, according to the Los Angeles Department of Water and Power.

Repair work was expected to take at least 48 additional hours and “maybe somewhat longer,” DWP General Manager Marcie Edwards said at a 2:30 p.m. news conference Wednesday.

After a water-main break on Sunset Boulevard, crews worked to make repairs on Wednesday, July 30, 2014.

The pipe break resulted in a 30-foot geyser and a 15-foot wide sinkhole on the street, which was subsequently closed between Hilgard and Veteran avenues. That shutdown was expected to continue through at least Thursday.

“We will not see Sunset Boulevard opened up today,” said Jamie Moore, spokesman for the Los Angeles Fire Department. “The DWP’s been working all night long … trying to remove the water, but we do still have water coming through that 30-inch pipe — it’s a huge pipe.

“Once we get all that water out, DWP is going to start working toward making its repairs and then they’ll start working with the [Departments] of Transportation and Public Works and trying to repair the street,” he said.

Residents of nearby Beverly Glen would be allowed to access their homes after providing proof of residence, officials said.

Meanwhile, a “very complex” operation was underway to repair the water main, said Jeff Bray, the DWP’s general superintendent for water distribution.

“The location of the leak is creating issues for us as far as the location of the pipe,” Bray said. “Normally, a break of this size, we would just go in and cut out a section of pipe and replace it real quick. But this is located where two large-diameter pipes come together.”

He stated that water in the area is safe to drink, and that no DWP customers had their service interrupted as a result of Tuesday’s incident.

At UCLA, the deluge caused “substantial” damage to six facilities including the famed Pauley Pavilion athletic arena, as well as two underground parking structures, a university official said.

The campus was open on Wednesday, with the exception of its two child-care centers. UCLA Camp activities were temporarily suspended, as were all campus recreation activities.
