Failure mechanisms and condition assessment of PVC push-fit joints in drinking water networks
This paper presents and discusses the significant role played by joints in the failures registered in drinking water distribution networks. The three most important failure mechanisms related are presented and a procedure to detect them through the visual measurement of the gap between pipes inside a joint is proposed. The procedure is proved to be a valuable source of information on joint ...

Contamination accidents in China's drinking water distribution networks: status and countermeasures
In recent years, frequent urban drinking water contamination accidents have caused significant impacts on society in China. However, emergency measures are primarily realized as management policies lack systematic technologies especially for those within-network contamination accidents. The aim of this paper is to perform analysis on cases of contaminant accidents that occurred in water ...

Impact of weather conditions on pipe failure: a statistical analysis
The occurrence of pipe failures in drinking water distribution networks may be influenced by weather conditions. In this work, a statistical analysis is performed to study the correlations between weather parameters and pipe failure in the Netherlands with the ultimate aim to predict the effects of climate change on network integrity. Failure data from a Dutch national failure database were ...

Decontamination of a drinking water pipeline system contaminated with adenovirus and
Escherichia coli utilizing peracetic acid and chlorineA contaminated drinking water distribution network can be responsible for major outbreaks of infections. In this study, two chemical decontaminants, peracetic acid (PAA) and chlorine, were used to test how a laboratory-scale pipeline system can be cleaned after simultaneous contamination with human adenovirus 40 (AdV40) and Escherichia coli. In addition, the effect of the decontaminants on ...

California Water Management Goals and Actions
Solutions like desalination and water reuse can help the arid state achieve water sustainability California has a Mediterranean climate, characterized by hot, dry summers and mild, wet winters. But climate change has resulted in uncertain water supplies and prolonged periods of drought, which in turn has led to water scarcity across the state. While water supply has diminished, water demand has ...

Reconciling ‘actual’ risk with ‘perceived’ risk for distributed water quality: a QFD-based approach
This paper explores the application of the quality function deployment (QFD) approach to identify and prioritize factors to reconcile ‘actual’ risk with ‘perceived’ risk for drinking water in a distribution network. Consumers' complaints (regarding water odour, taste, colour and other problems) and consumers' perception about water safety are used to define customers' requirements (aka ‘whats’). ...

iTOXcontrol safeguards intake Romanian drinking water (Toxcontrol)
The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company ...

Computational fluid dynamics modeling of contaminant mixing at junctions for an online security management toolkit in water distribution networks
The accurate modeling and simulation of the spread of contaminants within water distribution networks (WDNs) is an important task for drinking water security. In commonly used water quality simulation platforms the mixing of concentrations at junctions is assumed to be a complete mixing behavior. Experimental investigations have shown that this assumption is only true for certain flow ...

Saudi Arabia’s National Water Company Increases Water Storage
In 2012 the National Water Company (NWC) of Saudi Arabia undertook the enormous project of developing 43 wells and 46 water purification stations in 27 separate locations to provide sustainable potable water systems near Riyadh. To accomplish this task in a short six-month timeframe, contractors around the world were brought in to provide the necessary pieces of infrastructure required to build ...

Germany/Albstadt: How telemetry cuts the cost of leak detection significantly - Case study
Introduction Albstadt is a town located in southwest Germany, about 80km south of Stuttgart. Albstadtwerke are the utility network distribution provider in this region supplying potable water, natural gas and electricity. In addition to managing and maintaining the local distribution assets in Albstadt, Albstadtwerke operate and maintain two more potable water distribution networks, seven ...

Evaluation of drinking water quality in a water supply distribution network based on Grey correlation analysis
The lack of access to clean drinking water adversely affects public health and life expectancy in many developing countries. However, not all cities' drinking water can currently meet drinking water standards. Therefore, determining reasonable water quality changes and the influence of various factors on water quality is important for improving drinking water quality. The objective of this study ...
