TOTO’s proprietary EcoPower technology harnesses the kinetic energy of running water to power this high-efficiency faucet-eliminating routine battery replacement (and hazardous battery disposal) and the need for hard wiring (with its attendant labor and monthly electrical costs). The faucet uses 0.8 gallons per 60-second cycle, but because the average-use cycle is less than 60 seconds, the estimated water discharge is closer to 0.08 gallons per user. Circle 2
