The aim of the competition is to find a design that is functional, hygienic and reduces the need for potable water when flushing the units, the story stated.
Thirty winners will be awarded prizes in various categories when the deadline of submission, which is in July, has been reached, the story noted.

The best design will be showcased in the World Toilet Summit and Expo in November this year in China, the story added.
