A Capetonian civil-engineer by the name of Jonny Harris, have developed a revolutionary new toilet which, according to reports, uses 2 litres of water compared to the averaged 11 litres per flush. So theoretically, this new toilet can save you up to 30% on your water bill.
Named Arumloo, after the arum lily that has a natural vortex shape, which the new toilet mimics. The new toilet can connect to urban sewage systems as well as areas where there are no sewerage system, in which case it can connect to a septic tank or on-site treatment. The idea behind this is to bring equity to sanitation, according to civil-engineer, Jonny Harris.
