“…Pumping energy costs are inversely proportional to pipe costs, because larger diameters reduce head losses and consequently the power required for pumps, although they are more expensive. Reference [23] suggests simultaneously optimizing pipe diameters and pump selection, while [24] adds the pump location as part of the optimization process. In addition to these factors, the deterioration of other components, such as pipe roughness and leaks, can drastically affect the operating point of pumps, reducing their capacity and efficiency over the life cycle of the WDN.…”

Water distribution networks (WDNs) have a long life cycle, and understanding how infrastructure deteriorates over time can contribute to its efficient management. In this paper, a computational model is developed to simulate the deterioration of a WDN over its life cycle and analyze how its operation is affected, both hydraulically and economically. For this, four parameters are considered, changing over a 20-year life cycle: (1) an increase in water consumption due to population growth, modeled using statistical growth rates; (2) the deterioration of pipes, which increases according to a constant growth rate of internal roughness; (3) a change in leakage in the network, calculated based on population size, network length, and operating pressure; and (4) the deterioration of pumps, estimated according to their mechanical aging. The results point to maintenance services being essential for the efficient operation of WDNs, with leaks having the greatest impact on operating costs.

“…Pipes costs are inversely proportional to the energy costs for pumping, larger diameters reduce the head losses, and consequently, the required power by the pumps. [11] proposes a joint optimization for pipes diameters and pump selection, while [12] also includes the pump location as a problem in the WDN design. As can be expected, pumps also deteriorate during the WDN life, reducing its capacity and efficiency.…”

Water Distribution Networks (WDNs) are responsible for the majority of the costs in a water supply system. Thus, it is reasonable to carefully evaluate the possible interventions to achieve the one with the best cost benefit. Usually, WDN’s projects are designed for a life cycle of 20 years, but many systems are already operating longer than this, up to 100 years. Obviously, several maintenance services are necessary during this period, but the knowledge of how the system deteriorate can help the management of these services and keep the operational efficiency high, Therefore, in this work the deterioration of the components of a WDN is evaluated trough the economic losses generated and the pressure deficit. The pipe deterioration is modelled considering the roughness increases at a certain rate. Pumps deterioration are similarly modelled, considering the formation of internal roughness that increases the internal recirculation. Finally, the demand increase is also modelled considering the population growth rate and a minimum leakage flow rate. In addition, pressure dependent leakages are modelled as an orifice, maintaining its characteristics constant during the simulation. The results shown that maintenance services are essential for the efficient operation of WDNs, with leakages representing the most impactful problem.
