“…The MNF is commonly used as an indicator to assess losses in WDN and can be used to differentiate between apparent losses and real losses [61]. The existing literature contains several references where the MNF is applied to evaluate the leakage status of a WDN [62].…”

The central part of Chile has been in severe unprecedented drought for more than ten years, becoming a water-stressed area. ESVAL, one of the main water utilities in the Chilean water sector, is responsible for delivering potable water to the population and securing long-term supply in the vast majority of this area. In order to achieve this goal, ESVAL is implementing different measures, with pressure management being one of them. This paper aims to describe the works executed in La Calera city to implement a new advanced pressure management scheme on an existing pressure-reducing valve with two main targets: reducing leakage and improving the level of service to the customers. The results show that advance pressure management generates a 10.12% reduction in the minimum night flow while, at the same time, helping to improve the level of service to the customers reducing the number of times pressure falls below the minimum target set by ESVAL by 52%. It is concluded that pressure management facilitates quick water savings by optimizing the performance of existing pressure-reducing valves.

“…Therefore, ensuring a sustainable water supply is crucial to society's welfare and security today and tomorrow (Zanfei et al, 2022). To achieve sustainability and environmental priorities, water managers use various strategies; however, one of the most crucial aspects of designing and planning sustainable urban infrastructure continues to be investing in water distribution networks (WDNs) (Al-Washali et al, 2020;Oviedo-Ocaña et al, 2020;Ávila et al, 2022;Bui et al, 2022). Indeed, before or under abnormal conditions, proactive and protective actions must be taken to ensure customer service and achieve water supply reliability (Kang and Lansey, 2015), which is challenging given the risk and uncertainty associated with the poor pipeline infrastructure condition (Bui et al, 2022).…”

The management of network infrastructure in the context of water sector sustainability poses a significant challenge due to the increasing demand for fresh water, rapid infrastructure deterioration, and rising global water shortages. This paper presents a practical method to address these challenges by partitioning water distribution networks (WDNs) into district metered areas (DMAs) during critical hydraulic conditions to ensure adequate water supply, appropriate pressure and flow rates, and improved customer satisfaction. The proposed method employs efficient graph theoretic algorithms and a multi-objective optimization approach to reduce computational effort and determine the optimal dynamic layout of DMAs based on flow meters and gate valves, while minimizing variable installation costs and regulating water loss monitoring and management. The method ensures that only the number of flowmeters and gate valves may require modification, rather than the DMA layout, as hydraulic criteria may frequently change for a network due to various reasons. The effectiveness of the proposed method is demonstrated through successful implementation on six complex WDNs consisting of hundreds of pipes and nodes.
