Excerpts from Prof. OER Abheyratne's lectures on designing an out-door toilet.

 

1. The squatting plate is designed, so that one would always hit a 'bulls eye' every time when one used it, when defeacating.

2.  A tin roof was -

  "Hot in hot weather,

Cold in cold weather, was

Noisy during rainy weather and was

Not open to the skies"
