A Model for Selecting the Most Cost-Effective Pressure Control Device for More Sustainable Water Supply Networks

Water is one of the most valuable resources for humans. Worldwide, leakage levels in water distribution systems oscillate between 10% and 55%. This causes the need for constant repairs, economic losses, and risk to the health of users due to possible pathogenic intrusion. There are different methods for estimating the level of leakage in a network, depending on parameters such as service pressure, orifice size, age and pipe material. Sixty-two water distribution networks were analyzed to determine the leakage method used, the calibration method, and the percentage of existing leaks. Different efficiency indicators were proposed and evaluated using this database. Several cases of installation of pumps working as turbines (PATs) in water distribution networks were analyzed in which the use of these recovery systems caused a pressure drop, reducing the level of leaks and recovering energy.

“…Indicators force people to think about where development is taking them [81]. For the indicators to be able to cover the essential points, different authors divided their structure into different groups that included: (1) quality of service, (2) efficiency in planning and execution of investments, (3) operational efficiency, (4) efficiency in business management, (5) financial sustainability, (6) access to service and ( 7) environmental sustainability [37][38][39]. Different indicators are defined in Table 3.…”

The world is continuously searching for ways to improve how water is used for energy. As the population increases, so do the needs for natural resources and, in turn, the needs for energy. This research sought to show how the world has tried to achieve more sustainable forms of pressurized water distribution and to show the results that have been obtained. In this sense, technologies have been used for the production of clean energy, energy recovery instead of dissipation, reprogramming of pumping stations and hybrid systems. In many cases, much lower water and energy requirements are achieved and, in turn, greenhouse gas emissions related to water use are reduced. Sixty-one different water systems were analyzed considering different energy, economic and environmental indicators. The different operation range of these indicators were defined according to sustainable indicators.

Pressure control in water distribution networks (WDNs) provides an avenue for improving both their sustainability and reliability. The complexities of the networks make the problem more challenging as various situational operations must be accounted for to ensure that the entire system performs under recommended conditions. In general, this problem is addressed by the installation of pressure reducing valves (PRVs) in WDNs and determining their appropriate settings. Researchers have proposed the utilization of several control techniques. However, the limitations of both computational and financial resources have compelled the researchers to investigate the possibility of limiting the PRVs while ensuring their control is sufficient for the entire system. Several approaches have been put forward to mitigate this sub-problem of the pressure control problem. This paper presents a review of existing techniques to solve both the localization of PRVs and their control problems. It dwells briefly on the classification of these methods and subsequently highlights their merits and demerits. Despite the available literature, it can be noted that the solution methods are yet to be harmonized. As a result, various avenues of research areas are available. This paper further presents the possible research areas that could be exploited in this domain.
