In cosmopolitan areas and big cities of the world, shortage of drinking water during the peaks of consumption hours is a noticeable problem. Many people may not have piped water during these critical hours especially in summer times. To minimize this problem, an electronic control valve was designed and developed which saved about 70% of water in each showering session at Kerman city in Iran. The calculations showed that the price of conserved water during one year for a family with 5 members covers the price paid for the installation of the new automated control outlet.
