Abstract: | Abstract Water management in Spain is submitted to a non‐uniform geographical and seasonal distribution of water resources. The non‐uniform distribution of resources is worsened by the non‐uniform allocation of demand (mainly irrigation and urban). Because that, water supply, aquifers, and wetlands are driven to a high risk. Even though, there are examples of good water management, as is shown for the private industrial productivity of used water. Spain has a very long tradition in public water management (first water law in 1879) at different levels from ministry to municipalities, including users communities. A lot of these organisations are anchored in very old ways of doing, given private sector the opportunity to enter and grow up. A survey about it is presented. In the management of urban water, there are different organisations involved: central administration; autonomic, regional and metropolitan authorities; urban water suppliers and the sanitation authority. The recently approved changes in the former Spanish Water Law, limiting water rights and introducing water market, the new and expected Hydrological National Plan and the European Framework Directive, reinforce the opportunities of the private sector to enter, giving financial resources, technological advances and quick answers to new social concepts in water managerial procedures. We can observe how the Spanish administration uses private water suppliers' front desks to collect taxes and to supply capital to invest in infrastructures and water technology. The question that needs to be addressed is the nature and the impact of the privatisation process in Spain. The unrealistic water urban services price in Spain has been studied and it is presented and evaluated by regions, presenting a deficit to be covered in the future and been a significant gross value of the future business, which invite private sector to participate in. To give a general scope over the evolution of the roll played by the private and public sector, the case of Catalonia, the more evolved autonomous region of Spain in water management, is presented as an example of the future for the rest of the country. |
