Mieres

Can you build a house on rustic land?

Asturias allows a new house on rustic land only where the town plan provides for it.

DL 1/2004, art. 124. A town plan can be stricter.

Plan in force: Plan General (a full town plan), from 1996. The region's planning viewer ↗

The national urban information system (SIU) maps the land class for 100% of the municipality.

Only the town hall can confirm it, in writing: ask for a certificado urbanístico.

Is there water?

IGME records 11 wells and boreholes in Mieres. Half of the 2 with a depth found water at 5–345 m. Measured yields (4): 29–43 L/s, the middle half. 93 springs are recorded.

Ground: 93% practically impermeable.

Choosing where to drill takes a hydrogeologist.
