It can be concluded that based on the investigations so far performed, the on-site ecological sanitation treatment alternatives, are a favorable and partly superior alternative to traditional wastewater treatment. Further insights in transmission due to handling, collection and scaling-up is however necessary, since current investigations still have been done on a limited scale.
Regrowth potential of indicator organisms and bacterial pathogens are also of concern. Prospective epidemiological investigations furthermore can give insight in the impact of introducing these systems on a larger scale.
Bad water, sanitation and personal hygiene combined are after malnutrition globally considered as the major treats to human health. According to Michaud et al (2001) malnutrition accounted for nearly 6 million deaths (11.7% overall) and 220 million DALYs (15.9% overall) and the corresponding figures for poor water supply, sanitation, and personal hygiene accounted for 2.6 Million deaths and 93 million DALYs in 1990. These were considered the top 2 of risk factor groups for the total global burden of disease.
