WATERBURY, Conn. — Waterbury entered Monday, December 15, with thousands of residents still living through a citywide water crisis after a major transmission main failure on Thomaston Avenue that officials now say is far more severe than first believed. Crews have restored service to some neighborhoods and critical facilities, but large sections of the city remain without running water—and even where taps are flowing, residents are under a boil water advisory while state testing determines when it is safe to drink.

The impact is rippling across daily life in Waterbury and neighboring communities—from school closures and restaurant shutdowns to emergency fire protection being supported by tanker trucks. Officials say a full return to normal may still be days away, in part because the repair is no longer a simple patch: the city is now working to build new sections of main and create a bypass to route water around damaged pipe. [2]
What’s happening on Thomaston Avenue—and why the damage is “much worse than expected”
City leaders say crews were only able to fully assess the break once they safely reached the damaged area underground, and what they found changed the repair plan. Waterbury Mayor Paul K. Pernerewski Jr. told reporters the damage to the Thomaston Avenue water main is “much worse than expected,” pushing the city toward a larger rebuild of the damaged section rather than a straightforward fix. [3]
The failure is tied to a 36-inch transmission main serving much of Waterbury’s system, which the city says was compromised after an earlier break on the same roadway earlier in the week. The city’s official update describes the incident as a “large and complex failure of critical infrastructure” and confirms that restoring full service will require construction of new main sections. [4]
Local reporting has traced the broader context to Waterbury’s aging water infrastructure and a cascade effect from earlier failures. CT Mirror reported that an earlier failure of an older line undermined a larger transmission main, contributing to an explosive rupture late Friday night that sent pavement into the air and damaged nearby areas—underscoring how quickly a localized weakness can escalate into a systemwide breakdown when major transmission lines are involved. [5]
How many people are affected—and where service stands Monday
Across the weekend, officials and local outlets estimated around 100,000 people across Waterbury and parts of nearby towns were impacted by the outage and pressure loss. [6]
By Sunday into Monday, Waterbury officials said service had been restored in several areas—particularly downtown and parts of the west end—but a significant share of the city remained without water. CT Insider reported that about 60% of Waterbury was still without service as of Sunday, and the mayor said he did not have a firm timeline for full restoration. [7]
The city’s latest update lists restored areas including much of downtown, Bunker Hill, Town Plot, and the Country Club neighborhoods, while emphasizing that remaining areas require additional stabilization and repair work. [8]
Waterbury also reported that both of the city’s hospitals—Waterbury Hospital and Saint Mary’s Hospital—are fully supplied with water and operational, a key milestone after early emergency planning included tanker support and contingency measures. [9]
The boil water advisory: what residents can and can’t do right now
Even as water pressure returns in parts of the city, officials stress that the public health risk isn’t over.
A boil water advisory remains in effect for Waterbury and has extended into parts of surrounding towns during the disruption. The city says the order will remain until full service is restored and water quality testing is completed and approved by the Connecticut Department of Public Health. [10]
This has major practical consequences:
- Residents should not drink tap water unless it has been boiled (or unless they are using verified bottled/potable sources), per city guidance and the ongoing advisory. [11]
- Restaurants and food service operations have been told not to prepare or serve food while the boil water order is in effect, except for certain prepackaged items that do not require preparation. [12]
NBC Connecticut reported that restaurants in Waterbury and affected areas of nearby towns were told not to prepare and serve food while the order remains active, and that the advisory will stay in place until water is restored and tested for safety. [13]
Where to get bottled water Monday: distribution sites, hours, and home delivery help
To meet immediate drinking-water needs, Waterbury has continued organizing a large-scale potable water distribution effort with support from the Connecticut National Guard and volunteers.
In the city’s official update, Waterbury said distribution is running daily from 9:00 a.m. to 5:00 p.m. (or until supplies are depleted) at:
- Municipal Stadium (1200 Watertown Avenue)
- Crosby High School (300 Pierpont Road) [14]
CT Insider reported an additional access point for residents who can’t reach the drive-up sites by car:
- St. Vincent dePaul Mission (114 Benedict Street) [15]
For residents who are homebound or unable to travel, city officials have encouraged people to call 311 for assistance and potential delivery coordination. [16]
Officials say the National Guard has already helped distribute roughly 5,000 gallons of drinking water, and city leaders have indicated distribution will continue as long as needed. [17]
How Waterbury residents are coping: natural springs, YMCA showers, and “getting creative”
As the crisis extends into a new week, residents have been improvising—especially overnight and between distribution windows.
WFSB reported that with distribution centers closed Sunday night, some Waterbury residents turned to a natural spring on private property on Waterville Street, filling buckets and bottles for basic hygiene and household needs. The station described residents using the spring not just for drinking water, but also for showers and plumbing necessities. [18]
WFSB also reported several practical coping resources emerging locally:
- Showers available Monday at the Greater Waterbury YMCA, with residents asked to sign up for a time slot. [19]
- Home Depot on Bank Street filling buckets for free (customers must bring their own bucket, and supplies may be limited). [20]
The human toll is visible in small moments: parents juggling unexpected school closures, workers trying to keep clean for shifts, and neighbors sharing water and hauling containers for strangers. [21]
Schools closed and schedules uncertain
Waterbury Public Schools were closed Monday due to the ongoing impacts of the outage, and the city said school operations will be evaluated day by day for the rest of the week. [22]
WFSB reported that Wolcott public schools were also closed Monday, reflecting how the disruption has affected the wider region. [23]
Restaurants and businesses: “A disaster” during holiday party season
The timing—mid-December—has amplified the economic impact.
CT Insider detailed how the outage has forced restaurants to shut down during one of their most important periods of the year. Verdi, an Italian restaurant at the city-owned Western Hills Golf Course, was forced to cancel booked holiday parties, with the owner calling the outage a “disaster.” Even when water service returned, discoloration kept the restaurant from reopening immediately. [24]
City economic development officials told CT Insider that the disruption extends beyond restaurants, but food service is especially vulnerable because it depends on safe running water for preparation, sanitation, and customer safety. [25]
Fire and emergency services: hydrants, tankers, and regional backup
Beyond drinking water, the system failure has stressed public safety infrastructure.
CT Insider and city updates describe fire hydrants being impacted, prompting reliance on tankers from surrounding towns, with a regional tanker task force on standby. Officials have emphasized the importance of mutual aid while hydrants remain unreliable in affected areas. [26]
CT Insider also reported that Waterbury officials highlighted tanker deployment during a weekend fire response, including a scrap yard fire where additional water supply was used. [27]
Why the fix is taking so long: bypass construction, aging valves, and a fragile system
If residents are asking, “Why can’t they just replace the broken piece?”, officials say this break is occurring in one of the system’s most critical—and difficult—locations.
The city’s update says crews are working continuously to construct a bypass and new sections of main to divert water around the damaged area and restore service citywide. [28]
Earlier briefings also pointed to compounding infrastructure challenges: CT Insider reported that the age of the system, along with valve issues and uncontrolled water flow in the break zone, can slow the ability to isolate pipe sections and perform repairs safely. [29]
CT Mirror’s reporting adds another layer: Waterbury has been in the midst of a major upgrade push, but replacing or rehabbing a complex water network can’t happen overnight—and a major break can be even more disruptive when backup systems are offline for upgrades or testing. [30]
The bigger picture: repeated breaks and the push to rebuild Waterbury’s water infrastructure
For many Waterbury residents, this isn’t a one-off emergency—it’s part of a recurring pattern.
City leaders and local coverage have pointed to multiple major breaks in recent months, including a September incident that also forced school closures and widespread disruption. [31]
CT Insider reported that Waterbury has spent roughly $30 million this year on repairs and upgrades to the water system, with additional funding proposals aimed at replacing critical system components—such as valves—in the coming years. [32]
What residents should watch for next
As of Monday, officials are emphasizing a few key points for the days ahead:
- Restoration will likely be uneven, with some neighborhoods coming back online sooner than others as crews stabilize pressure and complete bypass work. [33]
- The boil water advisory remains until the city has full service restored and testing is completed and approved by the state. [34]
- Potable water distribution is continuing, with residents urged to use official sites and call 311 if they need help accessing water. [35]
The city has encouraged residents to follow official updates via Waterbury’s website and to contact 311 with questions or urgent needs as repairs continue. [36]
