Biological Sand Filters Low-Cost Bioremediation Technique for Production of Clean Drinking Water

ABSTRACT

Approximately 1.1 billion people in rural and peri-urban communities of developing
countries do not have access to safe drinking water. The mortality from diarrheal-related
diseases amounts to∼2.2 million people each year from the consumption of unsafewater.
Most of them are children under 5 years of age—250 deaths an hour from microbiologically
contaminated water. There is conclusive evidence that one low-cost household
bioremediation intervention, biological sand filters, are capable of dramatically improving
the microbiological quality of drinking water. This unit will describe this relatively
newand proven bioremediation technology’s ability to empower at-risk populations to use
naturally occurring biology and readily available materials as a sustainable way to
achieve the health benefits of safe drinking water
