WaterSaver Technologies Aqus System

GUILT-FREE FLUSHING

About 40 percent of freshwater coming into the average home is used just to flush the toilet. When tucked inside the cabinet below the bathroom sink, the Aqus system cuts that number significantly. Instead of using freshwater to flush, it catches the water that goes down your sink drain, filtering and disinfecting it and then quietly pumping it to your toilet tank. (The recycled water is even safe for toilet-slurping pets.) When there’s not enough wastewater for a flush, Aqus pulls from your plumbing. The system saves up to 14 gallons a day in a two-person house. $295; watersavertech.com
