thank you for describing again the processes involved in your system.
As you can very well understand, if we know the volume of wastewater flow, we can design a system that capable of handling the loading, regulate it, control it and ensure successful operation.
I asked this question for information on the material flow on 3rd April and I unfortunately I have not received a full response for it yet. I hope that in the next 10 days we will be able to do this as well as obtain responses for the other questions raised earlier.
In your paper, you wrote that

However when asked how much waste water is generated per day as influent
to the digested, you wrote on 8th April:

Is this a suggestion because the question was raised during this discussion or is this the practice ?
Since the latrine has been in operation since March 1998, dont you have a water meter at the latrine site that reads the water consumption ?
