Despite the recent improvements, there is still a problem of access to WASH services. This problem access is linked to poverty and inequality, which in turn cause difficulties in accessing water, thus creating a vicious cycle. This article analyses this vicious cycle using data from international organisations related to these issues. These data sh...

Energy consumption is one of the principal components of the operative costs incurred by providers of water services, both financial and environmental. Fortunately, in recent years solar panel technology has improved substantially, and photovoltaic self-consumption has become a tool that can reduce the costs of water reuse and other water services....

Energy consumption is one of the main costs faced by households, both financially and environmentally. This article analyses the energy consumption of Spanish households and the cost of installing solar panels in order to determine the potential of this form of energy production on a household level. The results show that households with a larger n...

The disposal of desalination brine, which contains a higher concentration of salts, is treated as waste and discharged into the environment. In this brine, several elements, when processing and extraction were possible, could be susceptible to exploitation and valorisation. Among all the ions existing in desalination brine, and whose industrial use...

The Tagus-Segura water transfer is a large infrastructure that allows the distribution of a large amount of water resources, which is associated with a significant energy cost. Therefore, energy improvements are a fundamental tool to reduce one of the main financial costs of the infrastructure, as well as the emission of greenhouse gases. For this...

Water pricing is one of the fundamental tools for water resources management. However, the current tariff structure in Spain has associated problems in relation to the composition of households. This paper analyses the current tariffs of Spain's Valencia region and studies the effect of alternative tariff structures. The results show an imbalance i...

El consumo energético es uno de los principales componentes del gasto financiero en la provisión de los servicios del agua. Este deriva, en gran medida, del suministro tradicional a través de la compra de energía a las empresas suministradoras, lo que lleva asociada una determinada contaminación. Esto justifica una persecución constante del desarro...

The Tagus-Segura water transfer has generated significant value in the region that receives its water resources. Despite this value, some agents seek the cancellation of this important infrastructure, arguing economic, environmental, social, and political problems. With the aim of providing information on the efficiency of the Tagus-Segura aqueduct...

This research examines the differences in the price for water supply for the Spanish households according to the type of household and the region of residence, which is of great relevance in terms of equity. The analysis covers the entire Spanish territory with the aim of establishing comparisons between regions, determining the current situation o...

There is an extensive bibliography that analyses the structure of a desalination project from the perspective of chemical engineering, but there is another "engineering" that has been much less studied, which is just as decisive for the plant to be able to operate. The aim of this work is to analyse the economic and legal factors that condition the...

Pollution from wastewater discharges requires the treatment of all wastewater to maintain water bodies in good condition, as well as the possibility of reusing this water. Thus, wastewater treatment is an activity that has developed significantly in the Region of Valencia and has significant costs, including energy, which represents the main econom...

This paper seeks to explain the internationalization process of Sadyt from 1995 (date of foundation) to the present day. This company, belonging to the Sacyr de Vallehermoso group, began its international expansion in markets such as Algeria, Tunisia, and Australia. Carrying out this case study focused on one of the companies is justified by its su...

La presente investigación examina la situación actual de la depuración de aguas residuales en la Comunidad Valenciana de España con el objetivo de obtener información relevante para mejorar la gestión de las plantas y estudiar la viabilidad de la implantación de tratamiento terciario en lugares donde no se disponga de él. Los resultados obtenidos m...

This research examines the water tariff applied to Spanish households with the aim of determining the adequacy of the river-basin approach established by the water framework directive (WFD). The analysis pays particular attention to Spain’s interregional differences in water prices, as well as determining the most influential factors in household w...

This research seeks to determine and analyze the reaction to an increase in the water invoice with the aim of introducing improvements in wastewater treatments. To this end, the purification situation is analyzed and the price elasticities of demand are obtained through Ordinary Minimum Squares. The results show that there are several small noncomp...

This paper has arisen from a reflection of the current reality in terms of the postulations about what is known as the Malthusian economy. Since the Industrial Revolution to the present day, despite there having been a high increase in world population, technology has played a fundamental role in the increase in the level of wealth per capita. Howe...

The aim of this study is to determine whether the high level of technological innovation detected in Spain’s industrial districts is, as the theory states, an intrinsic characteristic of these districts that was present in all stages of their evolution. To that end, and using figures on the number of patents filed, the trajectory of innovation is a...

There was a first phase of road-building efforts during the first third of the century which constituted the contemporary stage of road transport in Spain. This was followed by an extended hiatus until the end of the post civil war period, after which a new boost in road building took place from 1960 until the crisis of the mid-1970s with a signifi...

In April 2012 Argentinean Government nationalized 51% of Repsol shares in YPF. Expropiation of YPF is a new step in a broad list of protectionist and interventionist decisions, such as the nationalization of Aerolíneas Argentinas, nationalization of private pension plans, or the amendments of the Central Bank regulations to make the use of reserves...

The origin of the water supply system of Tajo-Segura, in 1932, goes back to when it was the unique possible solution to the shortage of hydric resources in the Confederación Hidrográfica del Segura (CHS). Its energy consumption is not homogeneous; it could be bigger or smaller, depending on the different water destination. The energy cost average o...

In the Marina Baja region there is a tradition of fierce competition for water resources which necessitates the regulation of institutions in order to satisfy the interests of the different water users. The management of the water resources in this region is based on the water exchange between the different users with no legal modification of the w...

Certain regions in the south of Europe are suffering an acute lack of water. One way to solve this hydric deficit is to use membrane bioreactors (MBR) to reuse the treated wastewater in tasks where drinking water is not required, e.g. irrigation. The aim of this research was to monitor physical–chemical (COD, BOD, and TN) and microbiological (EF, T...

The energy consumption of the Tajo-Segura water diversion is not uniform in all the different destinations of the water since, depending on the point to which the water must be diverted, more or less energy is required. The average energy expenditure of the Tajo-Segura water diversion is 1.21 kWh/m3. The energy costs of desalination depend on the t...
