Considering the current water shortages around the world, it's scary how much water is wasted by simply running the kitchen faucet when washing dishes or produce, etc. So, I was delighted to come across the Australian-made Hughie Sink ($25), a removable kitchen sink that captures 80 percent of the water that would normally be wasted, so you can reuse it to water plants, wash your pets or car, etc.
The sink is made of biodegradable plastic, is lightweight, comes with a sturdy handle, and fits most kitchen sinks. It's also available in a range of colors, so you can find one to match your existing sink. If you don't have any current use for the graywater, you should consider getting a rain barrel to store it, so you have it when you need it! Pretty clever and simple, isn't it?
