The toilets Eklavya Prasad showed are also filled with water from the floods.

Ways to deal with that:
-- Ensure feces are higher. (We have a design for that.)
-- Assure feces are isolated and somewhat aerobically composted or at least dried so the fecal coliform and pathogens are reduced by the time the flood mobilizes and spreads the latrine contents

Why do you need a pour-flush solution? To create a trap in the toilet?

Carol,
Agree about the ways you mention. My assumption is that the toilets MPA has advocated for and got built in some villages use exactly these same methods.

Is your following question directed to Katie? 

Why do you need a pour-flush solution? To create a trap in the toilet?

I don't know about Fiji in particular, but in many parts of the global south toilets are also also an aspiration and pour-flush or flush toilets are what people aspire for. One of the reasons why Roma et al (2013) found low satisfaction with UDDTs in eThekwini

Hi, Paresh.
I know Eklavya Prasad of Megh Pyne Abhiyan (I spoke at one of his events in 2012).
He also noted the flooding problem.
The urine-diverting dry and composting toilets (his are drying) (remember, that they model systems, they don't build them) are still flood prone.
But, as with most of what we discuss on this forum, any pathogens, including e. coli, in the excreta are already somewhat destroyed by the time the floodwaters mobilize the toilet contents. So these lower risk of cholera, et al.

With pour-flush toilets, you have a wetter process and possibly less deactivation unless you have set up the system as a biological/composting toilet system.

Pour flush is often used simply because it allows creating a trap, not necessarily due to status.
Someone still has to fetch water and the odor potential around the toilet is greater.
Flush toilets connected to piped water are often a high-status toilet---even when there is an obvious disease and odor connection!

We found with our Polynesian and Micronesian installations that closely coupling the benefit with the toilet helped get them adopted and built by the local population.
More on that later.
