Preheat the oven to 400 degrees F (200 degrees C).

Meanwhile, brown ground beef in a large nonstick skillet over medium-high heat.

Combine sauce and water in a large bowl. Stir in browned ground beef, ricotta, Parmesan cheese, and uncooked ziti. Pour ziti mixture into a 13x9-inch baking dish. Cover tightly with aluminum foil.

Bake in the preheated oven for 55 minutes. Remove foil and sprinkle with mozzarella cheese. Bake uncovered for an additional 5 minutes. Let stand 10 minutes before serving.
