Improving drinking water treatment without tariff impact: the Spanish case study
2017
Abstract Water is essential for our lives and activities. Everyone can drink good quality water, the question is whether they have access to it in the first place. Water quality and its treatment depend on the water source. This treatment has costs that users have to pay in the water tariff. It is very important to establish a water tariff that permits the best water treatment and has a low impact on the users. Cost functions are a useful tool to predict costs before an implementation or improvement. This article, using three easy steps (analysis, obtaining costs and modification of the water tariff) proposes improving water purification treatment using cost functions in order to find the b…
The importance of Hygienics and Clean Water Treatment in Valencia (1860-1910)
2016
El siglo XIX se caracteriza por numerosos cambios tanto a nivel social como estructural de la población: se produce un acelerado desarrollo urbano sin planificación y carente de servicios que da lugar a una mala calidad de vida y numerosas epidemias. Estos cambios tienen como resultado un nuevo movimiento, el Higienismo, que pretende mejorar las condiciones de vida de la población. En España, todas las reformas higiénicas se desarrollaron mediante los planes de Ensanche. Uno de los puntos clave de este pensamiento es el abastecimiento de agua potable como medio para evitar enfermedades. La ciudad de Valencia es un claro ejemplo de la importancia de este movimiento y cómo el abastecimiento d…
Evaluating the Efficiency of Water Distribution Network Sectors Using the DEA-Weight Russell Directional Distance Model: The Case of the City of Vale…
2021
In many cities, sectorization projects of the drinking water distribution network have been implemented. This study provides a methodology to evaluate the efficiency of the sectors of a water distribution network by applying a data envelopment analysis weighted Russell directional distance (DEA-WRDD) model. This non-radial DEA model gives the overall efficiency of each unit of analysis, as well as each input, output, and undesirable output considered in the evaluation. The variables used in the analysis provide a multidisciplinary view: economic factors (covering costs), water quality parameters, and technical aspects. The empirical analysis was performed for the sectors of the water distri…
