Reduction efficiency of index pathogens in dry sanitation compared with traditional and alternative wastewater treatment systems
Internet Dialogue on ecological sanitation
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.
