This book analyses the origin and evolution of the water supply service in Andalusia (southern Spain) between 1800 and 2020 from several perspectives. It does so from a historical perspective, to understand the evolution of the service over the years; from an economic perspective, as it is very useful to obtain an overview of the level of efficiency of the service; from a legislative perspective, as the regulatory framework of each era determines the models of management and provision of the service; and, finally, from an ecological and environmental perspective, of great importance in the New Water Culture and the protection of this resource. The volume's main objective is to contribute to the extension of knowledge and analysis of the processes of municipalisation and/or privatisation of this service in Andalusia, with the aim of providing those responsible for local governments and administrations, both political and technical, with useful reflection and illustrative information on the use of municipalisation and/or privatisation as instruments for the reform of the local public sector.
