in the Caldes stream basin
These private vegetable gardens historically irrigated with thermal water
had been deteriorated by wastewater contamination. The project
recovers the private horticultural landscape as a new self-managed open
public space. A participatory action research process with the irrigation
community and stakeholders allows co-designing two main interventions: a new pool to accumulate and cool the surplus water from thermal
spas recovering the irrigation system and a walkway over the main canal
were wastewaters are channeled. The process empowers the irrigation
community and recognizes the key value of traditional water management as intangible heritage towards urban sustainability.
