LOCATION
Barcelona (Catalonia, Spain)

YEAR
2018

CLIENT

Application of the multi-criteria analysis (MIVES methodology) for the management of the prioritisation of the maintenance of the water distribution network under sustainable criteria, i.e. considering aspects of an economic, social and environmental nature.
