Water management problems has resulted in a need to accurately measure the amount of delivered water from the product water-station to the citizen houses, especially in the remote poor areas, where the water networks are not available. There must be an accurate monitoring system for the quantities of water consumed in these areas to achieve a policy of equitable distribution. This paper aims to design a simple system, in which, an operator (with no experience) can run and use it by entering the required water quantity from a keypad and then starting the flow process. The system will calculate the water flow by a flow meter such that when the required quantity of water is reached, the water flow stops. The system computes the price and sends the quantity of water and the corresponding price to an LCD display and a storage medium. Such information would be available for simulation and reports over periods of time. Analysis of these data showed that the waste of water has been reduced by 44000 m3 monthly. The proposed system makes use of an AVR ATmiga2560 arduino microcontroller, a keypad, an LCD and an internal memory. Economically, the proposed system is very cheap and effective. It can replace the SCADA systems which cost much and it also does not need any training for use.
