Marina,
I don’t know alot about this topic but here is a little information that will get you started.
Dual flush toilets offer the user the option to flush with a smaller amount of water for liquid waste or a larger amount for solid waste. Many of these types of toilets are made in Europe. One company is Grohedal. You can find out more about their products and water savings buy going to http://www.grohe.co.uk. Once you are at the web site click on “Products” then click on GROHEDAL. Scroll to the information on “Flushing systems for the WC”. There is some information that may help you. You can also request informatin from them. Make sure you request it in English, unless you speak German. Geberit is another company that may make dual flush systems but I was not able to get alot from their site. Maybe your son could do more investigation on them. I hope this helps.
