Environmental Benefits and Economical Sustainability of Urban Wastewater Reuse for Irrigation—A Cost-Benefit Analysis of an Existing Reuse Project in…
2020
Besides benefits associated to increased water availability for irrigation, reuse projects of urban water can also provide positive environmental impacts, as they contribute to improve water quality of the receiving bodies by diverting wastewater from their outlet. This represents a typical win-win situation where significant synergies can be achieved between urban and agricultural sector, and the environment. These favorable conditions, however, do not necessarily imply that water reuse is either feasible from an economic perspective nor that the underlying supply chain is going to be triggered, if certain conditions are not met. Cost-Benefit Analysis (CBA) is considered a sound, theoretic…
Rainwater reuse in urban areas: a mathematical model and a longterm modelling approach
2018
Natural water resources are becoming increasingly limited due to global-scale climate change and water availability issues have become so severe that they must be addressed. Given these issues, reuse of wastewater and rainwater provides a promising way to cope with water shortages. This paper describes an investigation into the efficiency of rainwater usage systems. A conceptual model was built to assess the behaviour of rainwater tanks and their effectiveness in coping with water shortages. The study is based on a long-term simulation (12 years) of different rainwater reuse tank schemes. The associated reductions in residential freshwater demand (water reuse efficiency) and wetweather runo…

Current status and development of sanitation and wastewater treatment in the national and international context
2012
El acceso al saneamiento y depuración de aguas residuales es un aspecto de suma importancia tanto desde el punto de vista ambiental como sanitario. Por ello, desde el Imperio Mesopotámico hasta la actualidad se han producido importantes avances en esta materia. Sin embargo, en la actualidad, en la mayoría de los países en vías de desarrollo el acceso al saneamiento continua siendo deficitario. Por otra parte, los países desarrollados, que sí disponen de sistemas adecuados de depuración de aguas residuales, se enfrentan al reto de mejorar la sostenibilidad de estos sistemas. En este trabajo se describe en profundidad el estado actual y evolución en el tiempo del saneamiento y depuración de a…
Modelling the removal and reversible immobilization of murine noroviruses in a Phaeozem under various contamination and rinsing conditions
2018
International audience; Enteric viruses entering the soil with contaminated irrigation water can reach groundwater or be internalized in plants through their roots without being inactivated. Their fate in the soil depends on the virus, the soil and the soil solution. In order to write a mathematical model suitable for a Calcaric Phaeozem, we investigated the removal of murine norovirus and reversible immobilization in aggregate columns according to a saturation procedure, conditions between contamination and rinsing time, temperature and soil solution. Viruses were quantified before and after 0.45‐μm filtration with an RT‐qPCR (real‐time polymerase chain reaction). Experimental results supp…
