Water distribution systems event detection
2012 Complexity in Engineering (COMPENG). Proceedings, 2012Since the events of 9/11 2001 in the US the world public awareness to possible terrorist attacks on water supply systems has increased dramatically, causing the security of drinking water distribution systems to become a major concern around the globe.

Global Optimization of Water Distribution Systems
Proceedings of the 41st Annual Hawaii International Conference on System Sciences (HICSS 2008), 2008Recently [1] presented a new model for the solution of the water distribution network problem. The model captured successfully the essence of the problem structure, but could not guarantee global convergence. This paper adds, to the current research track, a new model and method that can guarantee global convergence for the water network design problem.

Redundancy model for water distribution systems
Reliability Engineering & System Safety, 2003Abstract This paper presents a model, based on head driven simulation, for assessing the redundancy of water distribution systems (WDS). The formulation recognises the pressure dependency of water consumption in the solution procedure. A new algorithm for pressure dependent modelling of WDS has, therefore, been developed.

At least half of the water works investment lies in the distribution system. Good service requires that the pipes shall have the ability to serve all the people all the time with adequate pressure at all places. In addition to this, there must be capacity to carry the water at rates required for good fire protection.

The Control of Water Distribution Systems as a Holonic System
2019Water Supply Systems (WSS) share close similarities with international standards that are widely used in the industry (specifically for food). Therefore, Industry 4.0 (I4.0) principles can integrate software modules and types of equipment among WSS developers and the end users.

Understanding distribution system WATER QUALITY
Journal AWWA, 2001Understanding distribution system water quality is a complex task because it involves not only numerous parameters but also the interactions among these parameters. This article highlights the development of a visualization tool capable of showing all types of information, (modeled and measured parameters), simultaneously or independently as a function

Distributed Reference Management Strategies for Networked Water Distribution Systems
IFAC Proceedings Volumes, 2011Abstract A distributed constrained supervisory strategy for large-scale spatially distributed systems is presented and applied to a networked water distribution system. The aim is at reconfiguring, whenever necessary in response to different supply downstream demands, the nominal set-points to the tank water levels so that all prescribed coordination ...

Model Generator for Water Distribution Systems
2018In the last decades, several different research questions arose in the area of water distribution systems. To evaluate the new models, techniques and solution methods, there is need of a large range of test models. In most research work the evaluation is performed on simple generated networks with no realistic size and properties.

Legionella in water distribution systems
Journal AWWA, 1998Regular culturing of distribution system samples is the key to successful disinfection.Legionnaires' disease arises from the presence of Legionella in water systems. Legionella can be found within biofilms throughout the entire water distribution system.

Uncertainties in Water Distribution Systems
Journal of the Hydraulics Division, 1981As a means of examining the uncertainties, the objective herein is to examine the sensitivity of the pressure difference, Δ P , in the analysis of a distribution network as a result of uncertainties in the parameters involved in the basic equation describing the flow.
