I would have no problem drinking recycled water, provided the equipment used to clean it, was well maintained.
Let's face it, over the years, waste water has been discharged to the sea untreated all over the World, then nature has put it back into rainfall and that has been going through the system for years and we have all been drinking it.
I bet this "toilet to tap water" would be a lot cleaner than a lot of the water supplied in many parts of Thailand.
