Optimization of the Jucazinho Dam water supply system through linear programming

Abstract

The growing increase in water demands in cities, generated by population growth, associated with environmental degradation, water losses in supply systems, low rainfall and failures in management systems, have resulted in water crises in the country, requiring the responsible agencies. , techniques that can solve the problems with the water deficit, so that the use and preservation of this resource occur regularly. Given this context, the present work aimed to optimize the water distribution, monitor the flow behavior from the optimization, with the elaboration of scenarios and verify the consumption in the cities supplied by the Jucazinho Dam Water Supply System - SAABJ. The Jucazinho Dam is located in the city of Surubim-PE, on the banks of the Capibaribe River, this system is responsible for the supply of 15 municipalities of the Pernambuco agrestic. The optimization of the SAABJ was performed using Linear Programming (PL) through the SIMPLEX method. It was found that the system under study, operating under the conditions of restriction of the imposed care regime, has been inefficient to hydraulically serve the municipalities under its responsibility. For the system to function efficiently, regularly and optimally, the rural areas of 6 municipalities cannot be serviced by it, and for the urban area, there must be a reduction of 98.09% in the amount of flow intended the city of Caruaru, which highlights the critical situation of meeting these demands only by this water source.
