4 . RINSE AND REPEAT

The water used by your household can then do double duty on a lawn or garden. Welcome to grey water recycling.

Water’s not black and white: There’s a grey zone. What goes down the drain after showers, toothbrushing, or laundry is called grey water (in contrast to black water which goes down the toilet). You wouldn’t drink it, but your plants can.

California-based Greywater Action runs workshops on reusing rainwater and drain water. Not all locations allow it, but in those that do, it’s relatively simple to set up. Here are some basics.

The easy solution

Projects that reuse grey water range from the professional to the DIY: a laundry-to-landscape system that can be made over a weekend with a few hundred dollars in parts. Install a diverter valve (分流阀) on the pipe of your washing machine. After a cycle, guide used water out through a PVC pipe to plantings.

Storage and use

Use a grey water project to rethink your landscape, suggests Greywater Action co-founder Laura Allen. Start with reducing typically thirsty lawns and then add climate-appropriate trees, bushes, and ground cover. Besides, grey water smells if it’s not used right now. Allen also advises flushing (冲洗) storage tanks daily.

Work the laws

If your city or state regulations ban the use of grey water, ask to have them reviewed. Diverting grey water can help conventional wastewater treatment systems last longer and reduce peak flow into channels. Also, it isn’t “grey” until it goes down a drain. So catch water that falls as the shower warms in a five-gallon container, then use it in your toilet tank or garden.

5 . The forest was full of shadows as Sylvie hurried through it one summer evening in June. The child hurried the cow through the dark forest to her grandmother’s home.

Suddenly the air was cut by a sharp whistle not far away. Sylvie knew it wasn’t a friendly bird’s whistle. She hid in some bushes. But she was too late.

“Hello, little girl,” a young man called out cheerfully. “I’ve lost my way. Can I spend the night at your house?” he asked.

Sylvie didn’t answer. The stranger began walking with Sylvie as she followed her cow through the forest. She was glad when she could see her grandmother standing near the farm house. The stranger explained his problem to Sylvie’s grandmother.

“Of course you can stay with us.” she said. The young man explained he was a scientist, who collected birds.

“Do you put them in a cage?” Sylvie asked.

“No,” he answered slowly, “I shoot them and preserve them with special chemicals.”

“I’ve been looking for a white heron(苍鹭),” he said, “It’s a very rare white bird.”

But Sylvie’s heart began to beat fast. She knew that strange white bird! Early the next morning, she quietly hurried through the forest. She finally reached a huge pine tree, and climbed to the top. Sylvie’s bare feet and tiny fingers grabbed the tree’s rough trunk. Sharp dry branches scratched her like cat’s claws.

Suddenly, a bird with broad white wings landed on a pine branch next to her. The white heron smoothed its feathers and called to its mate. She knew the wild bird’s secret now.
