Brian Donnelly and Chris Armstrong will forever have putrid memories of the Fourth of July after hundreds of gallons of raw sewage gurgled from the ground in front of their home overlooking Horsetooth Reservoir.

About 10:45 a.m. Monday, a breeze carried the potent smell of sewage across their property at the intersection of Larimer County Road 38E and Deer Trail Court.
