I requested that the present Bio- Toilet system in the Train coaches are unhigenic and inauspisious.
The Bio- Toilet system fecal matters are viewed which is unhigenic and inauspicious.
So the stem have to be modified as S shapedStem , so as the floating inauspicious matters shouldnot be viewed by the naked eyes.
