In a medium bowl, mix the soup, sour cream, eggs, and water until combined. Stir in the potato chips. Add the ground round and mix well. Transfer to an 8 1/2 X 4 1/2-inch loaf pan. Bake until an instant-read thermometer inserted in the center of the loaf reads 160° F, about 1 1/4 hours.
Let stand 5 minutes.
Drain off excess liquid and slice.
