Interesting idea and good intention, but how do we make people change their ways?.. Installing high efficiency plumbing fixtures is one way, some shower heads give a good shower experience while consuming less water. The average shower time is 8 minutes. Where water is abundant and energy is cheap, people may take much longer showers. One thought I have is to design a shower-friendly hour glass that measures 8 minutes, that way you get real time feedback. Maybe you'd feel a little guilty if your shower was too long, or maybe you'd feel great if you had a good shower in less time. Either way, changing habits depends on good will and awareness, as part of a cultural change, and that will take time. Please note that domestic water use in the US is only around 1% of the total, about 40% of the fresh water is used for cooling electric plants. If we really want to conserve water, we need to consume less energy, and/or develop renewable energy resources. Anyway, here's an interesting video on automatic shower in Japan: Cheers !..

The industry and agriculture are of more concern on fresh water resources. On domestic front there are developments in shower designs.

We like the idea of using less water, but we feel that it's very low impact. Most of the water is used by industry and not personal households. The proposal doesn't convincingly address a key question, which is how to get enough people to actually use less water while showering.
