DANBURY — A boil-water advisory has been lifted for Danbury residents as crews continue to make repairs on the water main that broke earlier this week.

Mayor Mark Boughton and city officials said early Thursday that water tests showed no evidence of contamination and received authorization from state health officials to lift the advisory.

Residents, businesses, restaurants, schools, child- and healthcare facilities are advised to flush their taps to clear plumbing of potentially contaminated water, according to a statement from the city.

Flushing water lines should include interior and exterior faucets, showers, water and ice dispensers, water treatment units or cooling towers, the statement said. City water can be consumed and used as normal after the flushing.

The boil-water advisory was put into effect Tuesday as crews began restoring water service and pressure to thousands of residents who lost them when a water main broke underneath Tamarack Avenue on Monday night.

Crews were forced to turn off several valves to stem the water flow and to fly in a specially fabricated part to plug a 16-inch main. Millions of gallons poured out of the pipe, which sat next to a high-pressure gas line, during the height of the emergency.

Crews were able to stabilize the gas line and restore service to most customers on Wednesday, although crews worked through Thursday to install a new valve on the 16-inch line that was isolated from the system before water was restored.

The portion of Tamarack Avenue closed to traffic for the work re-opened to vehicles late Thursday afternoon, Boughton said. Further work to repair the road itself will stretch into the weekend, so drivers should remain cautious and expect delays near the site of the break, he added.

Notification questions

Some residents have complained on social media that they did not receive personal notification of the city’s boil-water advisory

Boughton brushed off the complaints, saying the city published updates online and made a half-dozen “robocalls” through the city’s automatic call service vendor, for which it pays about $30,000 per year, he said.

Those calls do not go to every household in the city because some residents have unlisted landline numbers, because they never registered their cell phones with the service or opted out of it, he said.

‘The fact is, you couldn't have any more notification than we did between social media, the News-Times, TV, radio, the phone calls we did, our website — which is updated on a regular basis,” Boughton said. “At the end of the day, people have to at some point take responsibility for figuring out what's going on.”

At Wednesday night’s school board meeting, some board members said they heard complaints from parents who were confused by the district’s notification about the break. The district had been forced to close Hayestown Elementary and Broadview Middle schools, along with the state’s closure of Henry Abbott Technical High School, when the campuses lost water Tuesday.

Board member Emanuela Palmares urged the district to use its social media accounts more to send more frequent updates, but Superintendent Sal Pascarella urged parents to double-check their emergency contact information at their child’s school, which is used to make those automatic calls.

Residents also can opt in to notifications from the city online at www.danbury-ct.gov. About midway down the homepage is a link titled “Emergency Notifications” that prompts users to enter their information with Smart911 to receive text messages, emails and calls from the city.

What’s next

Water service has returned to normal now, although cleaning and restoring the site of the break will continue into the weekend, Boughton said.

Crews have worked almost round-the-clock since the break to make repairs, but Boughton said the utilities and public works departments should remain within budget, even with the overtime and new equipment.

“We plan to address to have breaks during the year and plan to use overtime, so it should be within the budget,” Boughton said.

The departments have not calculated the exact cost of the overtime, repairs, special charter flight or custom-made equipment needed to fix the break, he added. If it does become a cost overrun, the departments will need to ask for an extra infusion of cash from the City Council in June, Boughton said.
