Strategic valve locations in a water distribution system
Valves play a critical role in a water distribution system for subsystem isolation and flow or pressure control. Among them, subsystem isolation is required to repair or to rehabilitate a broken component and can be done by closing adjacent valves. To evaluate the role of valves, the concept of …

Critical Node Analysis for Water Distribution System Using Flow Distribution
<p>The expansive nature of water distribution system makes them susceptible to threats such as natural disasters and man-made destructions. Vulnerability assessment research efforts have increased since the passing of “Bioterrorism Preparedness and Response Act” in 2002 to harden WDS. This study …

Evaluation of water distribution system monitoring using stochastic dynamic modeling
… capable of simulating the operation of a water distribution system containing pumps and storage tanks, and subject to random demands and contaminant inputs. Long term operation of a hypothetical small town water supply system containing one pump station and one storage tank was simulated …

Nitrification Investigation And Modeling In The Chloraminated Drinking Water Distribution System
… nitrification in chloraminated drinking water distribution systems in a one and a half year field study. Seven finished waters were produced from different treatment processes and distributed to eighteen pilot distribution systems (PDSs) that were made pipes taken from actual distribution …

Bayesian belief networks to integrate monitoring evidence of water distribution system contamination
… false positive sensor detections in drinking water distribution systems. A BBN is developed that integrates sensor data with other validating evidence of contamination scenarios. This network is used to graphically express the causal relationships between events such as operational changes or …

Evaluation of water distribution system monitoring using a combined simulation-optimization approach
… to assess monitoring strategies for a drinking water distribution network. Multiple simulation trials of contamination events were used to create input data for an integer optimization problem. A network model, based on the Blacksburg, VA water distribution system, was used as the basis for a …

Development of a Pico conduit-hydropower turbin within a city's water distribution system
… such times, the monitoring and operation of water infrastructure become problematic. In combination with a culture of vandalism and theft of infrastructure components that have resale value, infrastructure becomes inoperable at an ever-increasing rate. Equipment functionality and levels of …

The role of biofilms in Legionella pneumophila transmission in drinking water distribution system
Biofilms in drinking water distribution systems (DWDS) or premise plumbing systems could facilitate the persistence and transmission of pathogenic Legionella pneumophila (L. pneumophila), thus raise human health concerns. L. pneumophila cells can accumulate in biofilms, be protected from …

GIS representation and assessment of water distribution system for Mae La Temporary Shelter, Thailand
ArcGIS is used to analyze water access in Mae La, Thailand, home to 45,000 residents living as refugees in a temporary camp. Drinking water for the shelter is supplied at public tap stands while water for hygienic purposes such as bathing and laundry is available via covered rope-pump wells which …

Role of Extracellular Polymeric Substances (EPS) on Biofilm Disinfection in a Model Drinking Water Distribution System
… are undesirable but ubiquitous in drinking water systems. This study investigated the role of extracellular polymeric substances (EPS) in the biofilm life cycle, including planktonic cells, attached biofilm, detached biofilm clusters and redistributed biofilm, in a model distribution system …

A Comparison of Risk Assessment Models for Pipe Replacement and Rehabilitation in a Water Distribution System
<p>A water distribution system is composed of thousands of pipes of varying materials, sizes, and ages. These pipes experience physical, environmental, and operational factors that cause deterioration and ultimately lead to their failure. Pipe deterioration results in increased break rates, …

A Market-Based Arid-Region Water Resources Planning Model: Application to the Guhai Water Distribution System, China
… national agriculture production, have confronted water supplying crisis triggered by the rapid growth of local economy. The Arid Zone of Ningxia Hui Autonomous Region (AZN) is one of the arid regions that severely suffer from water shortage. Since 1970s, local people has been relying on the water …

Characterising the microbial communities associated with the water distribution system of a broiler farm and their role in Campylobacter infection
… epidemiology remains a matter of debate. Water has rarely been identified as a possible source of Campylobacter contamination of chickens, but represents an understudied source. Research suggests that natural microbial communities might promote the survival of Campylobacter in …

Analysis of Fate and Transport of E. coli in Chlorinated Drinking Water Distribution System in the Presence of Natural Organic Matter
<p>Contamination of drinking water distribution systems can affect the public health adversely. Intentional intrusion of contaminants into the drinking water distribution systems have been a growing concern. In order to protect the public health, an effort is made to answer the need for improvising …
