Hi
I am designing systems for emptying latrines/toilets in Kigali (full thread on the problem here: and video of process here:
We pump the waste out from the underground pits using a vane pump to a 50L vacuum proof container- we then pour that into a 50L thin walled chemical container to carry to roadside transport (we only half fill so they can be carried).
I'd like to eliminate this pouring step and empty direct to barrels we can carry to the roadside. Barrels plus waste will need to remain <30kg for easy of carrying. Is there any way I can design a barrel that can withstand ~0.5-0.7 bar and still be convenient to carry to the road? Ok if its expensive - we have money for capital costs so we can import.
