South Africa (Commonwealth Union) _ Water restrictions have recently affected many households in some of South Africa’s largest cities; these restrictions have occasionally lasted for days at a time. Tough decisions have been required of people. For instance, if you had a bottle of water at home, would you drink it or use it to flush the toilet? Sanitation expert Dr. Preyan Arumugam-Nanoolal contends that throwing drinking water down the toilet is just not rational, especially amid water limitations. She has been analyzing several sanitation technologies with her coworkers.
In an interview with The Conversation, Dr. Arumugam-Nanoolal noted that a septic tank, a conservancy tank, or a toilet that flushes are examples of waterborne sanitation available to about 65% of South Africa’s population. 13% of pit toilets have no ventilation pipes, while another 19% have improved pit latrines with ventilation. The remaining population either uses buckets or toilets with a pour flush, a chemical toilet, or a composting toilet. Unluckily, 1% of people still defecate in the open because they have no access to any type of toilet facility.
South Africa has been experiencing extreme weather conditions over the recent years, which have led to a severe shortage of water. For instance, in 2018 Cape Town had to deal with a severe drought and the potential for water shortages. More recently, flooding in the city of Durban on the east coast caused extensive damage to the city’s bulk water and sanitation systems. It is just not practicable or sustainable to continue with waterborne sanitation given the issues the nation has with water supply and management.
Around nine to twelve liters of water are used by conventional flushing toilets for each flush. And that water is drinkable. Moreover, the performance of the present conventional wastewater treatment plants is frightening, according to South Africa’s most recent Green Drop study. Out of the 995 wastewater treatment facilities tested, only 23 were awarded the Green Drop designation by scoring above 90%.
