Background:

The WRC funded the innovation of a Micro Flush toilet, with the objective of reducing the amount of water required for flushing. The final prototype – branded as the “Arumloo” as its design mimics water movement in nature’s Arum Lily plant. The Arumloo uses between 1 to 2,5 litres of water per flush, using a dual-flush mechanism. A flush is achieved using an innovative pan design that creates a vortex to remove stools more efficiently and a gush of water (‘gush flush”) that enters into the P-trap (see photo). The elongated P-Trap with an inverted egg shape profile enables effective conveyance of waste at low water volumes and the convex shape toilet pan promotes an accelerating vortex action for effective clearing of waste. The prototype has been tested with synthetic stools made from soya paste and newspaper and toilet paper, and has passed the international MaP tests used for testing of toilets.
