At a certain point of the dam we can see the pipe that directed the water to the machines in the terraces. The construction of the barrage had the function providing enough water for the water wheels that ran the steam engine. The lake in front of house also allows to a privileged view of the Farm and of all the coffee plants besides providing a constant breeze to cool the house, functioning as a natural air conditioner.
Besides providing energy for the machines the water from the dam went through the sewage system to wash away the liquid sewage; it gives a decorative effect to the garden and offers security.
Since that time it was common in Europe to see castles and palaces decorated with water and this was certainly the objective here. All the vegetation around the dam receives more humidity from the ground, giving plants bigger resistance during the dry season, and favoring the fruitful ones in the orchard to the side, as well as the flowers of garden.
