Aquarion Water Company will be switching over water service in Newtown as part of a state Department of Transportation Project.  The relocation of the northern intersection of South Main Street and Pecks Lane is ongoing.  Aquarion will switch service to a new 12-inch-diameter water main by Cedar Hill Road.  Crews will be working along the southbound shoulder of South Main Street today in that area. Newtown police will direct traffic as the work is underway.  Water service is expected to be shut off from 9am to 4pm.
