Abstract(s)
O presente trabalho tem como objetivo avaliar o potencial de eficiência hídrica no Mercado Municipal de Bragança, propondo quatro cenários para a redução do consumo de água potável. Para isso, é proposta a substituição dos aparelhos hidráulicos por outros mais eficientes e também a utilização de águas pluviais para os autoclismos das bacias de retrete.
No cenário 1 é analisada apenas a substituição dos autoclismos das bacias de retrete, pois são os dispositivos de utilização com maior consumo no estabelecimento. No cenário 2 é proposta a substituição de todas as torneiras do edifício. No terceiro cenário propõe-se a utilização de águas pluviais para os autoclismos. O cenário 4 abrange os cenários 2 e 3.
Todas as propostas apresentam reduções consideráveis no consumo de água e nas faturas anuais. O cenário 4 que alia a utilização de águas pluviais na recarga de autoclismos, com a utilização de dispositivos mais eficientes, permite uma redução no consumo de água potável de 59,14% e na fatura anual de cerca de 11.016,19 €.
Com isso, a adoção de medidas para a melhoria da eficiência hídrica no Mercado Municipal de Bragança, pode contribuir em termos econômicos para o Município, como também ajudar a reduzir os riscos de escassez hídrica na região.
The present work aims to evaluate the potential for water efficiency in the Municipal Market of Bragança, proposing four scenarios to reduce the consumption of drinking water. For this, it is proposed the replacement of hydraulic devices by more efficient ones and also the use of rainwater for the cisterns of the toilet bowls. In scenario 1, only the replacement of the toilets in the toilet bowls is analyzed, as they are the devices with the highest consumption in the establishment. In scenario 2, it is proposed to replace all faucets in the building. In the third scenario, the use of rainwater for flushing toilets is proposed. Scenario 4 covers scenarios 2 and 3. All proposals show considerable reductions in water consumption and annual bills. Scenario 4, which combines the use of rainwater to recharge toilets with the use of more efficient devices, allows for a reduction in drinking water consumption of 59.14% and in the annual bill of approximately € 11,016.19. With this, the adoption of measures to improve water efficiency in the Municipal Market of Bragança, can contribute in economic terms to the Municipality, as well as helping to reduce the risks of water scarcity in the region.
