Households can meet or reduce their irrigation needs by reclaiming grey water, stockpiling and using rain water, and designing their landscape to feature draught-resistant fauna. Imagine a yard irrigation system that doesn’t add one penny to your household water bill. Residential water recycling technologies range from simple rain barrels and cisterns that collect rainwater to greywater recycling systems that collect and filter drain water from showers and faucets, and then redirect this water to outside irrigation systems.
