There is a Water main break in Danbury.  The issue on Merrimac Street near Peace Street was reported shortly after 8am.  The Public Utilities Department says the repair is expected to take 4 to 6 hours.  Residents in the area are cautioned that they may experience discolored water, low water pressure, or no water during that time.  Once the break has been repaired and water service is restored, the city will flush hydrants in the area to alleviate any brown water.
