furo / captação de água subterrânea (borehole)
Your own borehole for water when there is no mains supply. Taking groundwater counts as using a water resource, and it needs a permit from the environment agency APA.
Where you come across it. A plot in the interior of the country, talk of an off-grid house, watering the garden.
How deep the water is depends on the exact spot, not the region: there may be none a hundred metres from a neighbour who has it. The only way to find out is to drill, and you pay for the drilling whatever the result.
