Dear Chris：
The engineers do not like sit-down toilets.
The disadvatage of the squatting toilets is that it looks cheap and simple, only suitable for poor people， quoated some officials as saying. In early 1990s， SEI did managed to set up a lot of squatting UDDTs in Guangxi province and they have been replaced by normal flush toilets.
As a lesson， i must market the expensive Villa 9000 in China claiming that many rich people in western countries are using them.
This acadamy is to design eco-cities in China and I must show them them most advanced and expensive eco-toielts in the world.
best wishes
Scott

Hi Scott,

Do the users there prefer sit-down toilets?

Hopefully the architecture students will get interested in putting UDDTs in their buildings.

Best wishes,
Chris

Just before our lunar new year, I installed a Villa 9000 in the roof garden of Shen Zhen Construction Acadamy. Many architects will use the toilet learning UDDTs operation.

Now, our new leaders of the central geovernment are pushing a sustainable development policy in China. But, no people in China have clarified the definition of sustainability. ECOSAN toilets are not popular in China at all.

I will use the toilet to collect urine and have the feaces composted for growing vegetables in the roof garden.
