Preheat the oven to 350°F. Grease and flour two loaf pans and set aside.
In a large mixing bowl, cream the butter and sugar until light and fluffy.
Beat in the eggs, pumpkin, and water until well combined.
In a separate bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and cloves.
Add the dry ingredients to the pumpkin mixture, one cup at a time, mixing gently after each addition.
Divide the batter evenly between the two prepared pans.
Bake for about 1 hour, or until a toothpick inserted in the center comes out clean.
Let the loaves cool in the pans for 15 minutes, then remove to a wire rack to cool completely.
