The losses in the urban water supply networks have become a growing concern. There are several alternatives for the quantification, detection and monitoring of water losses. However, in general, water companies have budgetary and other constraints that hinder implementation. Therefore, this paper presents a model to aid the selection of a subset of preventive maintenance actions to control water losses while accounting for the water companies' restrictions. The model combines an additive multi-attribute value analysis by applying the SMARTER method to evaluate alternatives with Integer Linear Programming (ILP). The model shows to be efficient in order to achieve a portfolio of preventive maintenance actions, particularly when the decision maker considers that, there is a compensation for attribute evaluations.

“…That exponential behavior is the reason why the breakpoint at vertical line 4 is more clear than at vertical line 5: the more the exponential has flattened, the more the slope of the two successive exponentials differ and the clearer the breakpoint becomes. The recognition of a breakpoint in the pressure steps also allows location of the leak, just by using one pressure sensor [15].…”

Additive manufactured components have a different metallurgic structure and are more prone to fatigue cracks than conventionally produced metals. In earlier papers, an effective Structural Health Monitoring solution was presented to detect fatigue cracks in additive manufactured components. Small subsurface capillaries are embedded in the structure and pressurized (vacuum or overpressure). A crack that initiated at the component's surface will propagate towards the capillary and finally breach it. One capillary suffices to inspect a large area of the component, which makes it interesting to locate the crack on the basis of the pressure measurements. Negative pressure waves (NPW) arise from the abrupt encounter of high pressure fluid with low pressure fluid and can serve as a basis to locate the crack. A test set-up with a controllable leak valve was built to investigate the feasibility of using NPW to localize a leak in closed tubes with small lengths. Reflections are expected to occur at the ends of the tube, possibly limiting the localization accuracy. In this paper, the results of the tests on the test set-up are reported. It will be shown that the crack could be localized with high accuracy (millimeter accuracy) which proves the concept of crack localization on basis of NPW in a closed tube of small length.

“…However, the construction of distribution elements and the transportation of water from a single source to the entire urban area are not only economically infeasible but are also prone to leakages and pipe bursts along the transportation lines [2,3]. Leakages and pipe bursts are common failures in urban water distribution networks; when there is a major burst in the main pipeline, a complete shutdown of the water distribution process becomes imminent [4,5]. Decentralized systems are widely accepted as being more economically feasible, less prone to accidents, and one of the most promising approaches for improving the water management in urban areas [6].…”

A B S T R A C TThis study introduces a schematic methodology for smart water grids (SWGs) for use in water management platforms, which integrates information and communication technology (ICT) into a single water management scheme. SWG technology is seen as a promising solution for resolving recent critical global water problems. To ensure the security of water quantity, safety of water quality, and ICT-based water management solutions, SWG technology should integrate five prime research areas: (1) platform configuration in both water and ICT networks, (2) guarantee water resources including both natural and manufactured water, (3) intelligent control of water flow using bi-directional communication in water infrastructure, (4) better management scheme dealing with risk-minimization for assets in the water infrastructure, and (5) energy efficiency in operating and maintaining water infrastructure. Two platforms (i.e. water and ICT platforms) are introduced as examples of well-designed platforms for the management of bi-directional water and data flows in accordance with both the consumer's water demands and supplier's water distribution schemes, in both centralized and decentralized water distribution grids. To guarantee water resources, harvesting both natural sources (e.g. river, lake, groundwater, etc.) and manufactured sources (e.g. desalination, reused waters, etc.) is proposed as a top priority. Using the platforms and multiple water resources, the intelligent water grid control plays a key role in satisfying the consumer's as well as the supplier's water needs, using self-diagnosing sensors and ICT-based cooperative networks. Improved management in risk-minimization for water infrastructure assets requires the GIS-based information of assets, their historical changes, and their renewal plans according to monitoring/forecasting data, etc. To improve water infrastructure energy efficiency, low energy processes combined with alternative energy sources and smart power grid management are suggested as key cost-saving methods for water production and/or distribution. Thus, integrating the five prime research areas in SWG technology can provide water managers insight into planning water infrastructure and shed light on the roles of the SWGs in future smart cities.
