Thoroughly mix the beef, 1/2 cup soup, bread crumbs, egg, onion, Worcestershire sauce and black pepper. Place the beef mixture into a shallow 3-quart baking pan and firmly shape into an 8x4-inch loaf. Bake at 350°F. for 1 hour or until the meatloaf is cooked through. Let the meatloaf stand for 10 minutes before slicing. Heat 2 tablespoons pan drippings, remaining soup and water in a 1-quart saucepan over medium-high heat until the mixture is hot and bubbling. Serve the gravy with the meatloaf.
