WATERBURY, Conn. (WTNH) — A Waterbury apartment complex that houses seniors lost access to water on Monday night, according to city officials.

City officials originally thought a water main break impacted 180 apartment units at Nottingham Towers, however further investigation revealed that there was an internal problem at the complex that resulted in the water problems.

The building houses elderly residents and those who are part of vulnerable populations.

The water was shut off during the day on Monday for scheduled repairs. But when residents went to turn the water back on, that’s when pipes started leaking, causing flooding.

One resident said he saw the ceiling on the second floor coming down. So, they shut the water off again and it will remain off until more repairs are done.

A Waterbury official said all hands were on deck Monday to make sure the elderly citizens had the water they needed throughout the night.

Waterbury Emergency Management Director Adam Rinko quickly responded to the scene. Rinko said it took some work to find the source of the leak.

“We had opened up a few walls earlier when the fire Department responded, and we found numerous old, old repairs. We’re not sure what happened as far as what would make it different tonight, but as we look at those repairs, that’s where all the weak sites are,” Rinko said.

The city says they were able to get two full pallets of bottled water and workers passed them out to residents.

Cold water was restored to Nottingham Towers on Tuesday morning, according to P.K. Management LLC.

Contractors are still working on returning hot water to the apartment complex, officials said.
