Water Wastage Control with Intelligent Pressure Management in the Urban Water Distribution Network Using Multi-Point Controllers in Order to Manage the Crisis in Urban Drinking Water Supply

Crisis management is the knowledge that planning and complying with principles and standards before, during and after a crisis increases the human contribution in controlling incidents, and water crisis management is especially important in arid and semi-arid areas. Water crisis management as one of the The most fundamental issues of urban development are the unplanned growth of cities that disturbs the crisis management system in big and small cities. Controlling water wastage plays a significant role in Iran's dehydration crisis, which is one of the solutions for optimal use of available water resources. Unaccounted water, in addition to being imposed on the water stress of the country's cities, in terms of sources of income for water and sewage companies, it involves financial crises. However, as a result of excess network pressure, the undesirable phenomenon of leakage that is directly related to pressure occurs (Jahangir, Barani, Jahangir, 2013). Network pressure management is considered as the most efficient and simplest method among leakage reduction methods. The requirements of pressure management include reducing leakage, reducing consumption, reducing accidents, non-payment and efficient distribution of water. With the intelligent management of pressure in the water distribution network by multi-point controllers, in addition to controlling and supplying the pressure of the distribution network, the critical points of the network were identified and effective measures were taken to distribute the same pressure, which led to the reduction of production costs, The amount of field leaks, the number of branching incidents decreased by 31% and the number of main network incidents decreased by 37%.
