Diagnóstico operacional de sistemas de abastecimento de água: o caso de Campina Grande.

Abstract

Factors such as urban sprawl, lack of damage control, aging systems, modifications and expansions not covered, high operating costs, in addition to uncertainties associated with difficult operating conditions, making it a set of processes increasingly complex and problematic, resulting in unmet demand in quantity and quality, non-compliance with minimum pressures of supply and operational efficiency and without energy. In this paper, diagnosis system was developed to supply the city of Campina Grande (SACG), with the aim of supporting the improvement of management system. This improvement comprises: satisfying the demand of supply, reduce operating cost energy, reduce the number of on / off power for pumps and valves, reducing water losses and seek efficient operational procedures. The research consisted of examining detailed operational information and registration data of the whole system and computational modeling, by EPANET. it was noted the need to implement the rehabilitation plan and network of predictive and preventive maintenance for the operational units, it was found that you can set schedule for the daily operational SACG, given the criteria and reducing the hydraulic energy costs, it was felt that currently are not allowed to operate the system without the operation of the lift station- Gravaia at peak hours (17:30 PM to 20:30 PM), but it would be possible with reduced demand from 5% with practices to reduce physical loss and improvements in micro-measurement. The preventive maintenance activities can be carried out in the morning and last for two hours, will not harm the system. It was found that even.the system being operated in its extremes to meet demand, operating through the diagnostic procedures can be defined so that the operation becomes more efficient and more economical.
