It's an interactive toilet design that helps conserve water that has caught on quickly in countries where water is in short supply or in areas where water supply and treatment facilities are older or overtaxed. The concept of two different flush quantities for solid waste vs. liquid waste makes sense. There may be some reluctance to the luxury of the simple flush but as the cost of water and waste water treatment rises that choice may not be very wise. Bodily waste is a delicate topic, so delicate that culture can be as much a factor in affecting change as necessity. We keep our bodily functions under wraps, so any changes in our approach to handling them can create culture shock and resistance.
Water shortage throughout the world and in the US is growing and will continue to do so in the future. It is an economic and environmental necessity to change our usage now and the low flush toilets assist in that change.
