Residents and businesses in Paterson and Prospect Park: Please continue to boil water for at least one minute before using it for drinking, cooking, brushing teeth, washing dishes, or making ice—or use bottled water—until you are officially notified that the water quality is safe.

Water service may not return until the end of the week for residents in parts of Paterson, North Haledon, Haledon and Prospect Park, according to the Passaic Valley Water Commission.

That means 200,000 people are still under a boil water advisory.

A 30-inch water main broke on Friday in Paterson, which is proving very difficult to repair. Water is still pouring out of the broken 30-inch main that is 140 years old.

The Passaic Valley Water Commission says crews are still trying to locate the leak, which is 20- to 30-feet underground.

The utility is now setting up temporary pumping in two locations in Paterson to move water from an area of high pressure to those with no water.

Jim Mueller, with the Passaic Valley Water Commission, responded to a question as to whether the recent earthquake may have caused the break.

“Certainly, earthquakes don’t help when pipes are 140 years old. One of the complicated aspects of it is we don’t have reliable drawings of what is in the ground,” said Mueller.

Paterson is providing free water, bathrooms and showers at JFK High School from 8 a.m. to 8 p.m. for residents impacted by the outage. The three other cities are also providing free water to those in need.

The mayors of all four cities are asking for patience.
