Today is the 10th annual World Toilet Day. Sponsored by the Singapore-based World Toilet Organization, the event is meant to build awareness about the risks that lack of sanitation present to the physical, emotional and psychological health of 2.6 billion people around the world. Fortunately, poor sanitation is receiving an increasing amount of attention from NGOs, academics and other problem-solvers around the world. But there isn’t time to waste, since lack of hygiene contributes to diarrheal diseases that claim the lives of 1.5 million poor children each year.
Earlier this year, The Gates Foundation awarded a total of $3 million to researchers at 8 universities as part of its Reinvent the Toilet competition. Unlike the innovations that are taking place with flush toilets, these grants are aimed at designing, developing and prototyping waterless, hygienic toilets that cost less than $0.05 per user per day. The foundation also awarded a $4.8 million grant to the London School of Hygiene and Tropical Medicine (LSHTM) for a project called Sanitation Ventures. For it, researchers are developing ways to speed up the decomposition process in pit latrines. Organisms such as tiger worms, placed near the surface of the latrines, can effectively increase the speed of composting. Beneath that, in a filtration bed, liquid waste is further treated by aerobic bacteria. The end product is a treated sewage material that can later be used as a fertilizer.
And if that sounds gross, well, get over it. Human-waste-based fertilizer has been used in many parts of the world for centuries. The key is to process it correctly — at the right temperature and for enough time — to ensure that all pathogens are eliminated. In fact, aside from better public health, one of the major benefits of developing sanitation solutions for the developing world is creating an end product with value, such as fertilizer or biochar for energy.

According to the text, poor sanitation
As atividades em ambientes sem ventilação natural, com aberturas e saídas limitadas e com pouco oxigênio, são classificadas na segurança do trabalho como sendo atividades em espaços confinados, exigindo a obrigatoriedade de uso pelo instalador hidráulico dos EPIs adicionais:
Para as tubulações e conexões em PVC, utilizadas nas instalações prediais de água fria, considerando as variações térmicas, a norma da ABNT determina uma pressão máxima de
As conexões hidráulicas, curvas e joelhos, têm por finalidade realizar desvios de acordo com o ângulo da peça utilizada, 90° ou 45°, na direção do fluxo de esgotos. A diferença básica entre uma curva e um joelho é o
Os registros hidráulicos são componentes empregados nas instalações de água fria e quente dos sistemas prediais. Esses registros são divididos em três tipos, são eles:
As válvulas hidráulicas, que contam com êmbolos que permitem a regulagem da vazão em sistemas hidráulicos, são capazes de fornecer um fluxo constante e preciso de líquidos e podem ser usadas para calibração ou aplicações de fluxo regular, são denominadas como válvulas de
O motor hidráulico desenvolve torque devido à pressão aplicada nas superfícies dos dentes das rodas. Essas rodas giram juntas, porém apenas uma está ligada ao eixo do motor, o que o classifica como um motor
Por uma questão de manutenção, antes de se colocar em funcionamento qualquer bomba hidráulica, deve-se encher toda canalização de sucção com o líquido a ser bombeado, facilitando a lubrificação e evitando que a bomba funcione a seco.
Esse processo é definido comoOs resultados de ensaio de uma bomba hidráulica centrífuga, funcionando com uma velocidade constante, podem ser representados em um diagrama, traçando-se as curvas características de carga, rendimento e potência absorvida, e também
Nas instalações prediais de água fria com maiores comprimentos de tubos, maior número de conexões, tubos mais rugosos e menores diâmetros, haverá, consequentemente,
Em uma rede predial de distribuição de água fria, foi verificado um vazamento de 2 litros de água em um intervalo de 50 segundos. O desperdício da vazão em litros por dia será de, aproximadamente,
Golpe de aríete é a sobre-pressão em qualquer ponto da instalação, quando do fechamento de qualquer peça de utilização. A máxima pressão admitida acima da pressão estática nesse mesmo ponto deverá ser de
A pressão máxima a que podemos submeter uma tubulação, conexão, válvula, registro ou outro dispositivo, quando em uso normal, é definida como pressão
Para uma residência com cinco pessoas, foi definida a utilização da água de chuva para reuso na irrigação de um jardim com área de 500 m², onde são gastos 2 litros/dia/m². Considerando a frequência de irrigação de 12 vezes/mês, a quantidade em litros de água de chuva por mês é de
O recolhimento da água de chuva pode ser feito em três etapas: 1 – somente captação; 2 – captação e pré-filtração e 3 – captação, pré-filtração e tratamento. A etapa que faz a captação e pré-filtração resultará numa água com nível de qualidade considerado como
Nas estações elevatórias, as bombas podem ser instaladas em cota superior ou inferior a do nível das águas a serem recalcadas. No primeiro caso, haverá a sucção propriamente dita, sendo indispensável a instalação de válvulas de
Os sistemas hidráulicos de combate a incêndio, do tipo chuveiros automáticos, devem ser providos de uma conexão de ensaio dotada de uma válvula globo e de um bocal com orifício de diâmetro nominal igual ao do chuveiro utilizado na instalação e compostos por uma tubulação de diâmetro nominal nunca inferior a
