The list covers Granada, Albolote, Cúllar Vega and Atarfe, among other towns. Within 20 km of Granada are Eulogio Caravantes Iniciativas Geomineras, Sondeos y Perforaciones Granada and Ingedasa Asesores. Distance matters less for a one-off job than for servicing, so check how often they’ll come out to a rural plot.
Legalización Pozos/sondeos Belén Delgado and Ingedasa Asesores lead on Google among firms with at least 20 reviews. The average rating across the list is 4.7 (firms with at least five reviews). Look at how recent the reviews are; a strong score from years ago says less than a steady run of recent ones.
Ask for the price per metre and the expected depth, and check what the quote leaves out: casing, pump, cabling and the water analysis often appear later. A firm that has drilled in your valley before is worth a lot.
Questions to ask before you sign
- What depth do you expect in my area, and why?
- What is the price per metre?
- What happens if you don’t find water at that depth?
- Are the casing, pump, controller and water test included?
- Will you handle the authorisation paperwork?
