Preheat your oven to 350 degrees F. Spray two 9x5 inch loaf pans with cooking spray (or grease).
Whisk together the flour, baking soda, salt, baking powder and pumpkin pie spice in a large bowl. Set aside.
In a separate large bowl, combine sugar, oil and eggs, stirring well with a spoon to combine. Add pumpkin and stir again until combined.
Slowly add pumpkin mixture to dry mixture, alternating with the water. Stir well between additions. Fold in chocolate chips.
Pour into prepared loaf pans and bake for 60 to 65 minutes, or until a toothpick inserted in the center is removed clean.
Allow bread to cool in pans for 10 minutes before transferring to a wire cooling rack.
