For Sanvwilli Primary School, this was a first visit from the Water Explorers team. Not wishing to miss out, all three classes of 109 excited grade six's piled into a tiny classroom to learn about water pollution and how water is treated. Like the world over, Sanvwilli Primary School learners also have been experiencing water shortages and only 10 children in the class have access to tap water 24/7. This statistic is fairly representative on the world scale as only 1 in every 9 people have access to clean tap water. The rest of their families needed to collect water from community taps in the Edendale township. Before the children got the chance to experiment with different water filtration bottle systems, the learner explored how water treatment plants filter, clean and purify the potable water supplied by the municipality. They learnt that throwing things like nappies, women's sanitary material or any other objects that did not pass through a persons body first, resulted in the obstruction of septic tanks and water borne sewage systems leading to sewage over spill potentially contaminating water in river and under ground supplies. All the children brought 2 litre bottles of grey water from home, but with the early September rains, the garden did not need any watering, instead they chose to keep this water for the frequent periods of drought expected this Summer.
