Sustainability of iron sheet and timber sub-structure

Hello team,
Am well acquainted with the use of iron sheets and timber for emergency latrines sub-structure instead of concrete and would like to know how sustainable this can be on an household latrine with permanent structure. How can this design be used sustainably for latrines with permanent dis-largement?

Hi Lowalem.
Good idea but i don't think the structure is durable given the conditions in substructure. It would be worse if grey water containing salt finds its way there.

Dear Lowalem,

It would depend a lot on the climate, but considering the amount of salt in urine, I would expect there to be holes in the sheets after about 2 years. With possible collapse after 3-4 years or at the first time the pit is emptied.

Regards
