the practice of using water treated to energy-intensive potable standards for flushing toilets, washing clothes, and landscape maintenance is quickly becoming obsolete. More and more, Californians are turning to rainwater and graywater to address these water needs. In some cases, people are going even further by filtering their rainwater to potable standards of use, and using it for all their water needs. You can join the growing numbers of those making smart choices about water use.
Based on this chart from the American Water Works Association, utilizing rainwater at home for nonpotable purposes (landscaping, toilets, laundry) can reduce your potable water use by 76%. Using it for potable sources as well? That makes you 100% self-sufficient, without depending on city or groundwater supplies.
