ABSTRACT
One study on the impact of sanitation deficiencies on public health conducted in Brazil from 2001 to 2009showed that due to inadequate sanitation there were on average 13,449 deaths per year (1.31% of total deaths) (Teixeira, 2014). The annual average of compulsory notification on cases to diseases was 466,351 cases, with an expense of R$ 30,428,324.92 with medical appointments in this period (Teixeira, 2014). The origins could be found in poor socioeconomic conditions, lack of water resources availability and low awareness on water use (Costa Dos Santos & Benetti, 2014). In addition to the public health risks, there are occupational risks to consider, especially for sewage wastewater workers. During regular work they are exposed to toxic chemical and microbial risks, which lead to health problems and sometimes even deaths (Brown, 1997).
