Preheat oven to 350 degrees F (175 degrees C). Grease and flour three 7x3-inch loaf pans.

Mix together pumpkin puree, sugar, oil, water, eggs, and vanilla extract in a large bowl until well blended. Whisk together flour, baking soda, cinnamon, salt, nutmeg, and ginger in a second bowl. Sift flour mixture on top of pumpkin mixture. Fold in with a spatula until just blended. Pour into the prepared pans.

Bake in the preheated oven until nicely browned on top and a toothpick inserted in center comes out clean, about 50 minutes.
