- For other water sources or different substances, see man_made=pump.
- pump=powered - For wells that are drawn using a powered pump. Gasoline and electric are possibilities.
- pump=manual - For wells that are drawn using a pump powered by human locomotion.
- pump=no - For wells that are drawn without a pump. Wells like this are usually drawn by bucket and by hand.
