For the past several months a steady torrent of water has been coming out of this front yard, down the street, and down the storm drain. I drive past it daily and haven't seen it let up once. I initially though it might be normal runoff from higher in the neighborhood, but even when everything was frozen solid at 9 degrees this winter...water was still pouring down the street.

Photos on Google Earth from a couple of years ago don't show any water. Could it be a broken pipe or broken sprinkler? The attached photo doesn't show it properly, its a steady flow running down the street.
