Thousands of people in Waterbury remain without water Monday days after a water main broke on Thomaston Avenue Wednesday, leading the whole system to lose pressure late Friday night, officials said.

The entire city is still under a boil water order, and restaurants not serving pre-packaged food have been told to shut down if they do not have running water.

City officials say they are working to build a new water main that will divert water around the damage while repairs are being done.

Schools were also closed on Monday, and it was unclear when they will be reopening, with Mayor Paul Pernerewski saying closures will be evaluated "on a day-to-day" basis.

"It was a large failure, the pipe as we had indicated was washed out underneath it is collapsed," Pernerewski said on Sunday. "It is actually more significant than we had initially thought it was going to be, so it's going to take an effort to get that fixed. We continue to work on ways to get water to the full city as soon as possible." More than 100,000 customers -- which make up the majority of the city -- along with neighboring towns, such as Watertown and Walcott, originally lost water.

Since then, the city says it has been able to restore water to some of the areas, including downtown Waterbury and both of the city's hospitals.

Water bottles are being distributed at both Municipal Stadium and Crosby High School, while residents without a car can call 311 to find ways to get bottles delivered.

The Greater Waterbury YMCA is offering free showers.
