In this scenario, Pedro's father uses the following simple machines to do his work:

1. **Inclined Plane**: The ramp used to raise or lower the water tank from the truck to the ground is an example of an inclined plane. It helps reduce the amount of force needed to move the heavy tank.

2. **Wheel and Axle**: The wheels on the truck and the water tank itself function as a wheel and axle system. This allows for easier transportation of the heavy load.

3. **Pulley**: Pedro's father might use a pulley system to lift buckets of water from the well. A pulley helps to lift heavy objects with less effort by distributing the weight.

**Answer**: Pedro's father uses inclined planes, wheel and axle, and pulleys as simple machines to help with his work.
