“…By the end of the twentieth century, the country reported a water potential of 5610 km 3 /year for a population of 157,070,163 inhabitants, which represented a water availability of 35,732 m 3 /inhabitant (Rebouças et al, 1999). Von Sperling (2006), using data from the World Resources Institute, reported a per capita water availability of 47,125 m 3 /inhabitant/year. The National Water Agency of Brazil (Agência Nacional de Águas, 2005) estimated a water availability of 33,376 m 3 /inhabitant, based on the information related to surface waters with an average flow of 179,433 m 3 /s and a population of approximately 170 million inhabitants.…”

[Objective] The main objective of this research was to evaluate the potential for saving drinking water by using rainwater as a source of supply for non-potable purposes in two neighborhoods with social housing in the municipality of Viçosa, Minas Gerais, Brazil. [Methodology] The consumption statistics for each month of 2020 were used for each of the homes comprising the Benjamin José Cardoso and Sol Nascente Housing Complexes, and the fraction of drinking water that is destined in homes for non-potable purposes was estimated. The information corresponding to the monthly rainfall records of the last 50 years was analyzed and the monthly volume of rainwater that could be harvested in each house was calculated. [Results] The average monthly volume of rainwater that could be captured through the roof area of each dwelling is 3.39 m3. During the rainy months of the year, it would be feasible to save a higher percentage of water than that allocated for non-potable purposes. Sizing a rainwater reservoir that exceeds the monthly needs for non-potable purposes would allow the surplus of collected water to supply the liquid during the dry season. [Conclusions] Since the average percentage of savings in drinking water for both neighborhoods exceeded 53%, the saving of the monthly consumption can contribute to the reduction of payments for the drinking water service and the consumption of the liquid in the municipality, particularly during drought months.

“…As discussões atuais sobre a limitação nas reservas de água doce do planeta, vinculadas a preocupações sobre uma possível escassez futura do mais simples e precioso dos líquidos, conduzem obrigatoriamente a uma reflexão sobre a real gravidade destas previsões. A par da questão da qualidade das águas, sabidamente comprometida, em escala global, por atividades antrópicas ainda pouco controladas, resta a dúvida sobre a efetiva disponibilidade dos recursos hídricos (Sperling, 2006).…”

Os cemitérios são fontes potenciais de impactos ambientais, principalmente quanto ao risco de contaminação das águas subterrâneas e superficiais por bactérias e vírus que proliferam durante os processos de decomposição dos corpos, além das substâncias químicas liberadas pelos mesmos. Consequentemente, esta água contaminada, frequentemente, acaba sendo utilizada pelas populações vizinhas às necrópoles. Considerando-se que em significativa parcela de cemitérios municipais existentes não foram realizados prévios estudos hidrogeológicos e de saneamento, os mesmos constituem-se em um alto potencial de risco de contaminação para as águas subterrâneas. O objetivo do presente estudo é descrever o potencial de contaminação do necrochorume gerado pela atividade cemiterial sobre as águas subterrâneas, enfatizados os riscos de contaminação ambiental e de saúde pública.
