“…WEN studies focusing on the demand end use data collected from the household (Wanjiru et al, 2016;Vieira and Ghisi, 2016), commercial or industrial sectors (Thiede et al, 2016), including tourism (Becken and McLennan, 2017) and municipal sectors, and are highly likely to be conducted using a bottom-up data collection process. This may allow effectively addressing social issues; for example, the relations between energy (fuel) poverty and water poverty, and might be able to find technological means for reducing poverty in water and energy (Vieira and Ghisi, 2016).…”

The intrinsic links between water and energy have produced a new concept known as water-energy nexus (WEN), which has been increasingly studied by scholars and global institutions since the 1990s. This paper provides a review of water-energy nexus studies in an interdisciplinary manner starting from two major approaches-water for energy and energy for water-which focus principally on quantitative studies, but also on policy and institutional dimensions. Many studies mention data collection, the lack of coordination between existing frameworks and the scale/boundary of the two resources as major challenges, whereas new technologies are seen as an opportunity for the nexus perspective. After identifying research gaps, the political ecology approach is proposed for a critical reflection on WEN. Additionally, water poverty and energy poverty (or fuel poverty) are also proposed as part of WEN studies in order to broaden their spectrum to include the demand-end perspective and introduce a social dimension in WEN. Keywords: water-energy nexus; political ecology; water intensity; energy intensity; households Resum. L'estat de la qüestió sobre el nexe aigua-energia i les perspectives futures d'investigació: des de l'oferta fins a la demanda finalEls vincles intrínsecs entre aigua i energia han originat una nova terminologia, l'anomenat nexe aigua-energia (NAE), que ha estat investigat cada vegada més per acadèmics i institucions globals des de la dècada de 1990. Aquest article presenta una revisió interdisciplinària dels estudis de les interrelacions entre l'aigua i l'energia a partir de dos enfocaments principals: l'aigua per produir l'energia i l'energia per subministrar i tractar l'aigua. La revisió se centra principalment en estudis quantitatius i en les dimensions polítiques i institucionals del NAE. Molts estudis esmenten la recollida de dades, la descoordinació dels marcs interpretatius existents i l'escala o límits de dos recursos com els desafiaments principals, mentre que les noves tecnologies es veuen com una oportunitat. Després d'identificar les àrees deficitàries en investigació, la l'autora proposa l'enfocament de l'ecologia política per endegar una reflexió crítica sobre el NAE. Es proposa també incorporar la pobresa hídrica i la pobresa energètica a les llars com a part dels estudis de NAE, ja que estan relacionades amb aquesta aproximació teòrica. Això permet ampliar l'espectre d'investigacions per incloure la perspectiva de la demanda i generar, així mateix, una reflexió social sobre el NAE.

“…Recovery. An assessment of the energy saving potential of several integrated water management systems in Brazil found that reducing the wastewater treatment at the centralized systems was preferable (more energy saving) to using alternative water sources in terms of water sustainability (Vieira and Ghisi, 2016). van der Hoek et al (2016) successfully utilized an adaptive policymaking method to develop viable strategies regrading resource recovery in Amsterdam's wastewater chain.…”

A review of the literature published in 2016 on topics relating to water reclamation and reuse is summarized. The review is divided into the following sections: 1) General: monitoring and assessment, social awareness and acceptance, and energy and resources recovery; 2) Treatment technology: integrated technologies, membrane treatment, reactors, WSPs, disinfection, and others; 3) Planning and Management: modeling, LCA, GHG emission, and case studies. Much of the water treatment research focused on the integrated technologies and membrane treatment.

ABSTRACT. This article shows an estimation of water expenditure in multifamily residential buildings in the city of Joinville, located in south Brazil. The proposed method includes an investigation of the water expenditure and an evaluation of the particularities of each building. The investigation was accomplished in thirty buildings and the collected data allowed a classification of the buildings and a measurement of the water consumption rate. The water consumption in buildings with individualized and collective water measurement systems was analyzed. Furthermore, a comparative study was done between the water consumption in buildings that have at least one pool and buildings without any pools. Some buildings in the sample have an alternative water supply system; however there is no measurement of the water consumption in none of the cases analyzed in this study. The per capita consumption was 224 liters per person per day. The buildings with individualized water measurement had smaller consumption per capita than the buildings with collective measurement, showing a reduction of about 34%. The buildings with pools had consumption per capita nearly 48% more than the per capita consumption in buildings without pools.Keywords: consumption indicator, water measurement systems. Estimativa do consumo de água em edifícios multifamiliaresRESUMO. O presente artigo apresenta a estimativa de consumo de água em edifícios residenciais multifamiliares na cidade de Joinville-SC, localizada na região Sul do Brasil. O método proposto inclui a investigação do consumo de água e avaliação de particularidades de cada edificação. A investigação foi realizada em 30 edifícios localizados na região central da cidade e os dados coletados permitiram classificar os edifícios e quantificar o indicador de consumo de água. Foi analisado o consumo de água em edifícios com medição individualizada e com medição coletiva do consumo de água. Além disso, foi realizado um estudo comparativo entre o consumo de água em edifícios que possuem pelo menos uma piscina e edifícios em que não há piscinas. Alguns edifícios da amostra possuem sistema alternativo de abastecimento de água, porém não há medição de consumo de água em nenhum dos casos analisados neste estudo. O consumo per capita calculado foi de 224 litros/habitante por dia. Os edifícios com medição individualizada de água apresentaram menor consumo per capita que os edifícios com medição coletiva de água, com uma redução de aproximadamente 34%. Os edifícios com piscina apresentaram um consumo per capita aproximadamente 48% maior que o consumo per capita de edifícios sem piscinas.Palavras-chave: indicador de consumo, sistema de medição de água.
