So there’s drought tolerant, and there’s the next step: reusing some of the wayer you’re already using to serve another positive purpose. I’m learning about greywater and am currently researching (via Nicholas mostly) how to funnel the water from our laundry and select sinks* to grow plants in our gardens.
*apparently only specific types of sinks are eligible in California, depending on what they are used for and what sodium and chemical content is in the soaps you use.
