The water main broke with such force that it caused the hill to slide. Though, the water company says its an act of God that land moved & caused the line to break. I think from the damage the water was already occurring from the water that was leaking but the water company will never admit that. Probably won't fix it either.
Recently a lot of water mains have been breaking in my local area, I was coming home late & happened across this one that looked like a geyser.
