  1. Tecnologías de depuración y reutilización: nuevos enfoques

    Trapote Jaume, Arturo
    This paper examines the principal current technologies of urban wastewater treatment and reclamation for reuse, and delineates the trends in these fields. The type of treatments and technologies cover a wide range of combinations of aerobic and anaerobic processes, fixed and suspended biomass, intensive and extensive systems, centralized and decentralized systems, etc. In addition to optimizing the efficiency of treatment processes, trends in I+D+i are largely focused on the elimination of the so-called emerging contaminants and the development of technologies of reclamation for reuse, which include membrane processes. In any case, future technological developments should prioritize the efficient and sustainable...

  3. Reutilización de aguas y ocio: campos de golf

    Ortuño-Padilla, Armando; Fernández Aracil, Patricia
    The dramatic numerical increase of golf courses in the last decades in eastern Spain, along with the growing concern about the sustainability of water resources, has sparked an intense debate about the relationship between golf courses and real estate development over the demand for water. Thus, this article will focus on the emerging types of housing complexes linked to golf as a starting point for analysis. Next, we will consider the application of reused water for irrigating golf courses by estimating the number of homes in the real estate development complex —approximately 2.000 to 3.000— required to keep the sporting...

  4. Aproximación al régimen jurídico de la reutilización de aguas regeneradas en España.

    Molina Giménez, Andrés
    This article analyses the legal regime applicable to the reuse of reclaimed water in Spain, starting with the general legislation concerning water, followed by the specific legal framework that regulates this unconventional resource. This legal scheme is sufficient to generate a stable framework and confer legal protections to stakeholders involved in this activity. However, further regulation on financing should be required, so as to clarify the responsibility for paying the costs of this activity. The regulation favors the use of these waters by those who hold the discharge permit and therefore by those who carry out the treatment. In our...

  6. Reutilización de agua para la agricultura y el medioambiente

    Melián Navarro, Amparo; Fernández Zamudio, María Angeles
    This article analyses reused water for agricultural and environmental purposes. After proper purification treatments have been applied there are many options available for the use of the reclaimed wastewater, but most of it is used in agriculture. It is possible to reduce the overexploitation of aquifers with this additional source of water, and we can take advantage of the nutritional value of the water to reduce the amount of fertilizers used in commercial farming. In the next decades it seems that in addition to agriculture reclaimed water will be used increasingly for different urban and environmental purposes. At the environmental...

  7. Depuración y reutilización de aguas en España

    Melgarejo Moreno, Joaquín; López Ortiz, María Inmaculada
    The issue of wastewater treatment and the reuse of water is of great importance, especially in areas where the shortage of conventional resources is a structural problem, as it is in the case of Spain. The likelihood that this unconventional, strategic resource would become scarce is unquestionable, particularly in cases where water planning and exploitation systems prioritize the preservation, protection and improvement of water quality, as well as the sustainable and efficient use of natural resources. This paper shows how wastewater treatment and reuse are linked, as the reuse of wastewater is associated with a previous regeneration, and both of...

  8. Reutilización de aguas regeneradas: aproximación a los costes de producción y valoración de su uso

    Villar, Alberto del
    This paper has two main objectives. On the one hand, it analyses the costs of available reclaimed water and the associated production of goods and services. On the other hand, it seeks to determine the economic value of the activities sustained with these resources. It has been possible to analyze water treatment projects and related initiatives representing more than 20% of the total reused water in Spain, which has yielded estimates of the indicators of investment and operating costs, as well as an average production cost of about 1.10 €/m3. Indicators of productivity have estimated that the economic value of...

  10. La reutilización de aguas depuradas regeneradas a escala mundial: análisis y prospectivas.

    Prats Rico, Daniel
    The article presents the situation of reused wastewater globally. At the outset we describe the parameters used to establish the higher or lower water deficit are, as well as the different regions where water supplies are under stress. The main causes of the worldwide increase of this problematic are reviewed. It includes a brief survey of historical events related to the use of wastewater and a description of the possible applications of this resource. Worldwide, the status of reused waters for different countries and regions is reviewed based on studies conducted in 2008 and 2013. The essay addresses the main...

  11. El agua mercantil: de las concesiones a los contratos y otras formalidades (México, 1880-1976)

    León Fuentes, Nelly Josefa
    This article analyses how water in colonial Mexico underwent a process of privatisation and incorporation as a public utility. Since then it has been subjected to forms of control and regulation by municipal governments and private initiatives backed by economic and political power. The information available reveals distinct modalities in the management processes that regulated the provision of water in the cities and their contribution to the modernization of the country from 1880 to 1940. One relevant aspect of the text underlines the financial, organizational, and technical scope and limitations of municipal administrations, which in turn illustrate the vulnerability and...

  12. Métodos de valoración ambiental aplicados a la regeneración y reutilización de aguas residuales en agricultura

    Alfranca Burriel, Oscar
    The economic and financial analysis of wastewater reuse systems projects has laid emphasis on the issues of private costs and benefits, both because of methodological difficulties related to estimating existing externalities and the lack of available data needed for its measurement. Taking full account of the environmental costs and benefits allows for a substantial improvement in the design and management of public and private wastewater reuse systems. Consequently, an improvement is also obtained in the management of investments in the treatment systems. The main objective of this paper is to present the essential theoretical foundations for the main environmental valuation...

  14. La ampliación del suministro de agua en la Lima colonial a fines del siglo XVI: los primeros problemas y sus soluciones

    Rivasplata Varillas, Paula Ermila
    In 1578 Lima had constructed a system of water distribution that brought the spring waters to the city. The rejoicing about the arrival of water at the Plaza Mayor did not last very long because the system had economic, technical and sanitary problems, which the authorities tried to solve while simultaneously extending the pipeline along the city. Drinking water availability in private and public fountains meant power and prestige for the city and its residents.
