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?
No well or borehole is recorded in Zarzalejo. That is not proof there is no water: ask local drillers. One spring is recorded.
Ground: 100% practically impermeable.
Choosing where to drill takes a hydrogeologist.
