Preheat oven to 350 degrees F (175 degrees C). Grease and flour three 9x5 inch loaf pans.

In a large bowl, combine sugar, pumpkin, oil, water, and eggs. Beat until smooth. Blend in flour, cinnamon, nutmeg, baking soda, and salt. Fold in chocolate chips and nuts.

Bake for 1 hour, or until an inserted wooden toothpick comes out clean. Cool on wire racks before removing from pans.
