According to a new county-produced video (above), Arlington has 500 miles of water mains, 60 percent of which are 55 years or older. The oldest water main in the county dates back to 1927. Such water mains are vulnerable to rapid temperature changes.
“In the winter months, with extreme temperature fluctuations, breaks and leaks are common,” the video narrator says. “Crew members are prepared to work in all weather conditions, day or night, to return water mains to service as soon as possible.”
Arlington water officials monitor water pressure changes that could be a sign of a water main break. But the county also relies on reports from citizens.
To report a water main break, residents can call Arlington’s 24-hour emergency hotline at 703-228-6555.
