I spend a good deal of time working in the U.S. Southwest. There has been an ongoing drought spanning approximately a decade throughout the region. Although substantial El Niño rains and snows have helped, they have not alleviated the water shortages brought on by consumption and the drought conditions. As a result, efforts have been made to conserve water and reduce consumption or pumping from groundwater reserves, as well as encouraging measures to recharge groundwater.As an example, communities promote the use of low-flow or no-water toilets and recycling of household graywater flows. Now another potential way to recycle or reuse
