Brown the ground beef; drain.
Stir the spaghetti sauce and water into the ground beef.
Put a little bit of the sauce mixture into the bottom of a 9x13 pan. Then layer noodles, cottage cheese, spaghetti sauce mixture, Parmesan cheese and mozzarella cheese.
Repeat the layers two times.
Bake at 350 for 1 hour or until browned and bubbly.
