WEDC – The three-pot water treatment system

The three-pot water treatment system, 2013.


The simplest method of treatment is storage in a covered pot. If the water can be stored for at least two days, schistosomes (small larvae which cause bilharzia) will die. It will also contain considerably fewer bacteria because these slowly die off because the conditions in the pot are not normally suit able for their survival and multiplication. Pathogens (i.e. disease causing organisms including some types of bacteria) attached to suspended solids will settle to the bottom of the tank together with the solids, further purifying the stored water.
