+* `water_well` - A location where water can be extracted from the ground. If known, `kind_detail` will give information about water potability and pump type, with values: `drinkable_powered`, `drinkable_manual`, `drinkable_no_pump`, `drinkable`, `not_drinkable_powered`, `not_drinkable_manual`, `not_drinkable_no_pump`, `not_drinkable`. The prefix `drinkable` indicates drinking water, `not_drinkable` indicates not drinkable water. The suffix `powered` indicates a powered or automatic pump, `manual` indicates a manual pump, and `no_pump` indicates that the water must be raised without a pump (e.g: a bucket and line). If information about the pump is not available, the `kind_detail` will be either `drinkable` or `not_drinkable`.
