The boil water advisory in Hoboken has been lifted, but a three-day-old water main break is still causing problems.

SUEZ Water has been working to fix both the water main that broke Sunday morning and a century-old valve that failed Sunday night, disrupting a transmission main that feeds water from Jersey City into Hoboken. Chris Riat, senior director of operations at SUEZ Water, said Hoboken's water system is being fed from an interconnection in Weehawken.

"The system has stabilized, pressures have returned," Riat said. He said that there are some buildings that may continue to experience problems, particularly during peak hours during the morning and late afternoon.

Riat, Hoboken Mayor Dawn Zimmer and Hoboken Police Chief Ken Ferrante addressed the public at City Hall on Tuesday afternoon.

Zimmer said the best-case scenario is having the water fully restored by the end of Wednesday, while the worst case would be another several days. She said water trucks will still be available for residents through 10 p.m. Wednesday.

"I am pleased that we do have the water supply we need to keep our city safe and operational," Zimmer said.

Ferrante said there will still be road closures in effect as the city continues its cleanup efforts. Several blocks remain closed in the southwestern portion of the city. Businesses in that area say they have been struggling since the water main break caused flooding, but roads are starting to dry up.

Anyone travelling for the holiday is asked to use public transportation. Zimmer said that anyone coming into Hoboken should enter from the north.

Residents who live on the upper floors of high rises may also notice fluctuations in water pressure or slight discolorations, but SUEZ Water officials say that it is safe to drink.

A water conservation advisory will continue for residents in Hoboken and Hudson County. Residents are urged to conserve water whenever possible.

A boil water advisory may have to be reinstituted when the main is fixed and water flows through its regular system once again.
