Rehabilitation in Intermittent Water Distribution Networks for Optimal Operation

Equitable distribution of water is a growing source worry, and concerns systems’ managers as water-stressed areas steadily increase situations scarcity are becoming more frequent. The problem goes beyond just the sector globally affects many countries’ economies since resources have multiple uses (i.e., power generation, irrigation, etc.). One various strategies to overcome periods extreme events (e.g., scarcity) adoption intermittent operation. Intermittent operation can minimize losses, manages supply same demand (in terms volume) during reduced period time. However, despite minimizing energy consumption necessary cope with increased flows head loss, due number operating hours, increases. This paper explores strategy based on rehabilitation system’s main pipes. It also considers optimal selection scheduling pumps aiming at improving hydraulic parameters velocity losses) reducing costs. Both resizing pipes optimized using Particle Swarm Optimization. obtained results show that this significantly reduce consumed be economically feasible.
