“…Water networks bring together stakeholders such as the private sector, the academic environment, civil society, non-profits, and the government. Water networks lead to open collaboration innovation, and innovation is a key element of water networks and a key element in providing a safer and sustainable water environment (AquaSPE, 2015;Creaco & Pezzinga, 2018;Sirsant, Hamouda, & Shaaban, 2023;Zhou, Gao, & Simpson, 2016).…”

In 2024, the preservation of water resources is an important dimension of the global economy striving for a sustainable, equitable and inclusive economic development and growth strategy. The preservation of water resources is an important component in the advancement of the 2030 Agenda for Sustainable Development Goals (SDGs), as established by the SDG 14, and in the development of a sustainable, equitable, and inclusive global Blue Economy. The 2023 UN Climate Change Conference-COP 28 Water Agenda emphasized the vital role played by freshwater resources in the global quest to address sustainable, equitable, and inclusive global economic growth and development. This paper elaborates on the promises and challenges permeating the establishment of a dynamic Blue Economy in Brazil's Amazon region. This paper introduces a Quintuple Helix and a Quadruple Helix framework of analysis to assess the promises and challenges facing the development and establishment of a sustainable Blue Economy in Brazil's Amazon region.

“…A consistent supply of clean water is the first and most critical community service that people need. A safe supply of potable water is the basic necessity of mankind; therefore, water supply systems are the most important public utility Creaco and Pezzinga [1]. The network distribution system is used to supply water from its source to the point of usage Ahmad Fuad et al, [2].…”

“…Creaco and Pezzinga [6] explored the simulation and optimization modelling, topology and partitioning, water quality, and service effectiveness. Creaco and Pezzinga [7] had shown how water pipe replacements and control-valve installations could be optimized in water distribution networks to reduce leakage, with minimum nodal pressure constraints.…”

As the leakage behaviour of water distribution network is considered a critical and lifethreatening issue, so this behaviour of water distribution network systems has been investigated experimentally and numerically, based on the effects of different positions and flow rates of the leakage outlets, and taking into consideration the flow hydraulics and pipe geometry. A laboratory model of the actual water distribution network studied was constructed. The laboratory water distribution network model is horizontal and has 16 loops with a total length of 30m in different diameters. The leakage position in the laboratory water distribution network was altered between main, sub-main, and branch pipelines with different flow rates. The characteristics of the ideal laboratory water distribution network with no-leakage were first studied; and the water distribution network system parameters were calculated theoretically using the Hardy-Cross method with seven iterations. The studied water distribution network system was simulated using computational fluid dynamics technique, Ansys. Fluent 18.2. The aim was to modify the old water distribution network by sensing the pressure values using dispersed pressure sensors. Also, from the pressure map of the laboratory water distribution network, the leakage position, if any, could be located. Depending on the sensed pressure, the control circuit was programmed to close the corresponding solenoid valves. The leakage flow rates were 0.1, 0.25, and 0.4 L/s; and changed between the main and sub-main pipes. The maximum pressure drop was around 500pa at the node directly preceding the leakage point at leakage flow rate 0.4 L/s. The performance of the used solenoid valve was simulated using the Matlab-Simulink technique. The simulation results showed the response to stepdown control signal was over-damped with steady state error of 2% and settling time of 0.6 s.

Water resource management is a topic of great environmental and social relevance, since water must be preserved and managed to avoid waste, providing high quality service at fair tariffs for the consumer, as imposed by the European Water Directive (2000/CE). In the rehabilitation of a water distribution network, it may be suitable to recover decommissioned water tanks, if any, rather than afford high construction costs to build new ones. In this case, the assessment of the residual service life of these concrete structures affected by steel bar corrosion is the premise for the design of new pipeline routes, connecting them. For this aim, rather than carrying tests that can accurately determine mechanical properties of the dismissed water tanks, it is possible to empirically estimate their level of degradation. Their conditions infer on the expected life of the restructured water distribution network. However, they allow the aqueduct to be used for its technical duration, assumed to be equal to the decommissioned water tanks residual service life in the case they do not require maintenance. Here, a simplified model for the assessment of the residual service life of decommissioned water tanks is first proposed and then applied to a case study, consisting of a part of the water network managed by “Ausino S.p.A. Servizi Idrici Integrati”, Cava de’ Tirreni, Italy. Once the service life is assessed, the QEPANET plugin is used in QGIS to speed up the design of the new pipeline routes in the georeferenced space, thus overcoming the limits offered by the classic EPANET solver.
