One of the main factors to measure the economy of any country is its gross domestic product rate and the agricultural sector is one of its key entities. To support the agricultural sector, water is the main source to irrigate dry lands. This research entitles the idea of implementation of wireless sensor networks as remote terminal units (RTUs) and local control for supervisory control and data acquisition applications. These RTUs measure various factors including land and air humidity, type of field and its temperature. On the basis of this information, the amount of water needed at different types of fields can be supplied and fortunately great amount of water can be saved for other commercial applications. It has been visualized in this research that with the implementation of the proposed method on Pakistan’s irrigation network, the productivity of lands can be increased by approximately 20–25% and yearly 2150 cusecs of water can be saved.
