Rainwater Harvesting
As with Solar and Wind harvesting, how much you can collect depends largely on your geographical location's general weather conditions, but most heavily populated areas have adequate rainfall. In some areas (such as tropical islands) rainwater harvesting is crucial for survival during the dry season, as it can provide all water needs for 6 months before rains begin to replenish the supply. Whilst rainwater is safe to drink, urban pollution makes it unwise to do so. It is most usefull in combination with recycled water for uses such as flushing toilets, for which greywater is unsuitable, so that a complete system can be installed which requires no ongoing effort. eBookRainwater-Harvesting.pdf - Additional information on Rainwater Harvesting.
