In Cambodia there's a problem in the floating villages with children drowning at night when going out the defecate over water, but worse is of course is the many many children dying of diarrhoea from dirty water - https://www.theguardian.com/global-development/2017/feb/15/s...
I see both arguments, perhaps creating a business model around making human waste worth money might create a solution. This has been looked at as a way to empty indoor toilets in India (vs open defecation) But I think treating it as toxic is the way forward.
In the 1% countries 'Urban Fish Ponds' could/should mean wetlands. Ignore the environmentalists, we have weakened many eco-systems thought day in/out living, we need to give back the fundamental basis of life, water. Don't restore wetlands, create them in new places inland.
