Great Harvest Pumpkin Bread

This is supposed to be a pretty good copy cat recipe of the delicious Great Harvest Recipe.
2 1/2 cups white flour
1 cup whole wheat flour
3 cups sugar
2 teaspoons baking soda
2 teaspoons cinnamon
1 teaspoon nutmeg
1 teaspoon salt
16 oz cooked or canned pumpkin puree (not pie filling)
1 cup oil
4 eggs, beaten lightly
2/3 cup water
1 cup semi-sweet chocolate chips 

Preheat oven to 350°F degrees for about 60 min . Grease two (9x5 inch) loaf pans or three (8x4 inch) loaf pans. 

Mix flours, sugar, baking soda, cinnamon, nutmeg, and salt together in a large bowl; set aside. 

Mix pumpkin, oil, eggs, and 2/3 cup water together and stir into dry ingredients. Stir in chocolate chips. Place batter in prepared pans.
