in addition to technical, economic and environmental factors, public acceptance plays an important role in successful treated wastewater reuse projects. the aim of this study is to evaluate yazd citizens’ awareness regarding water and wastewater issues and public acceptance towards wastewater reuse by questionnaire-type survey. for this purpose 250 questionnaires were distributed and filled out...

Wastewater consists of a complex mixture of substances. During wastewater treatment these harmful substances can be eliminated or degraded. However, persistent compounds released with the treated sewage effluents enter the environment and pose a risk to animal and human life. To determine the potential risks involved, screening tests are needed to monitor wastewater for potential toxic contamin...

This paper addresses the current imperative to develop and test urban ET algorithms, incorporate these into urban water balance models, and develop these into tools to underpin and guide Water Sensitive Urban Design (WSUD) and integrated urban water management. Two approaches to modelling the urban water balance focusing specifically on urban evapotranspiration are presented: i) SUES (Single-so...

The aim of this study is to analyze the urban water cycle in the Turin Metropolitan Area (Northwestern Italy), with a focus on quantifying the annual life cycle energy consumption and greenhouse gas emissions. The study made use Material Flow Analysis and Life Cycle Assessment methods for a defined urban water cycle system (ATO3) operated by one water utility (SMAT S.p.A.), and examines all mai...

Fecal indicator bacteria (FIB) have long been used as a marker of fecal pollution in surface waters subject to point source and non-point source discharges of treated or untreated human waste. In this paper, we set out to determine the source(s) of elevated FIB concentrations in Cucamonga Creek, a concrete-lined urban stream in southern California. Flow in the creek consists primarily of treate...

Water resources are under pressure worldwide, resulting in scarcity and deterioration of freshwater quality. According to European directives, we could reduce the on water urban areas by increasing reuse treated wastewater, reducing impact bodies, promoting recycling through multiple uses wastewater. Besides need address supply challenges, wastewater treatment systems show environmental steward...

In this work, the issue of hospital and urban wastewater treatment is studied in two different contexts, in Switzerland and in developing countries (Ivory Coast and Colombia). For this purpose, the treatment of municipal wastewater effluents is studied, simulating the developed countries' context, while cheap and sustainable solutions are proposed for the developing countries, to form a barrier...

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in s...
