Abstract：Water consumption in cities is closely related to the development of water resources. This paper divides the urban water supply network into several independent measurement zones (DMA) by water companies, and sets up flow meters at the entrance of each DMA area to monitor the water consumption in the DMA area. This method is an important means of pipe network leakage control management and operation management. This paper searches for relevant data, according to the water use pattern curves of residential quarters, factories, government departments and institutions, their time distribution is significantly different, then according to the measurement results, the water use pattern curves are drawn by matlab, and compared with the collected curves, the typical water use patterns in this area are identified; according to the data, the typical water use patterns are identified. The relationship between pressure, flow volume and time, the relationship between the minimum water consumption and the date, and the leakage pattern are analyzed. According to the results, the trend of water consumption (rhythm of life and production) is analyzed. Identify the typical water use pattern and identify abnormal patterns. Finally, the applicability, rationality, advantages and disadvantages of the model are scientifically analyzed and evaluated by the fitting degree between the model and the actual situation.

Keywords： Applied mathematics Water consumption Pressure Water use pattern Water leakage mode Abnormalmode.
