So I have concentrated on three water sorces. Rain, water system witch is now in use and recycling used water from first two sources. If we can manage to reduce fresh water consuption and raise recycled one we will have a lot of water saved. We are talking about some kind of buildings own water cycle. Water used by sinks, showers and washing machines would be filtered and reused, so would be water used for toiled flushing from wich we will get compost that we can use in agriculture. that compost would be transported like garbage is.
Second idea is to make people aware of water problem with posters that graphicly show shortage of this important liquid.
Third thing to do is to design toilets and other stuff that consume water less of a water gobblers.
