Sanitation is based on 5500 years old technology - time for a change
            
                Sanitation is destroying water resources at 500+bn litres per day, and a minority of the world population have flushing toilets. We must ask why there is so little progress on relevant SDGs, and why the so-called developed world are having sewage spills daily (UK 800+  daily)
