Methodology to Enhance the Reliability of Drinking Water Pipeline Performance Analysis
Currently, water utilities are facing monetary crises to maintain and expand services to meet the current as well as the future demands. Standard practice in pipeline infrastructure asset management is to collect data and predict the condition of pipelines using models and tools. Water utilities …

Risk-based Renewal Prioritization Models (RPM) for Potable Water Pipeline Infrastructure Systems
Water pipelines are critical infrastructure assets buried across the United States, responsible for delivering safe drinking water at adequate pressures from source to customers. A majority of these pipelines were installed in the mid-twentieth century without adequate financial planning for future …

Application of Geographic Information System and Probabilistic Analysis for Water Pipeline Renewal Prioritization
Aging infrastructure such as the water distribution system needs to be rehabilitated and maintained to provide uninterrupted and intended service, and to minimize possible failure with minimum expenditure. The failure of water distribution system is inherently uncertain and cannot be predicted …

Development Of A Performance Analysis Framework For Water Pipeline Infrastructure Using Systems Understanding
The fundamental purpose of drinking water distribution systems is to provide safe drinking water at sufficient volumes and optimal pressure with the lowest lifecycle costs from the source (treatment plants, raw water source) to the customers (residences, industries). Most of the distribution …

Effect of Installation Practices on Galvanic Corrosion in Service Lines, Low Flow Rate Sampling for Detecting Water-Lead Hazards, and Trace Metals on Drinking Water Pipeline Corrosion: Lessons in Unintended Consequences
Corrosion of drinking water distribution systems can cost water utilities and homeowners tens of billions of dollars each year in infrastructure damage, adversely impacting public health and causing water loss through leaks. Often, seemingly innocuous choices made by utilities, plumbers, and …

A signal oriented stream processing system for pipeline monitoring
… acoustic and pressure transient methods for water pipeline monitoring as query plans consisting of signal processing operators.

Design of a robotic water-pipe rehabilitation
Corrosion in water pipeline causes leak and forms tubercle at the vicinity of leaks. Various in-pipe robots have been developed in recent years for locomotion and inspection along the pipeline. Not much focus is put on in-pipe operations such as pipe maintenance and rehabilitation. This thesis …

Analysis and design of an in-pipe system for water leak detection
Leaks are a major factor for unaccounted water losses in almost every water distribution network. Pipeline leak may result, for example, from bad workmanship or from any destructive cause, due to sudden changes of pressure, corrosion, cracks, defects in pipes or lack of maintenance. The problem of …

Real time water pipes leak detection using electromagnetic waves for the water industry
… sensor for the detection of leaks/cracks in water pipes. As old metal pipes corrode they start to become brittle, resulting in the potential for cracks to appear in the pipes. In addition corrosion can build up resulting in a restricted flow of water in the pipe. Using an electromagnetic (EM) …

Development of a Novel Performance Index and a Performance Prediction Model for Metallic Drinking Water Pipelines
… authors have developed many different types of water pipe condition and failure models using the various methodologies available. Contrary, current utilities are struggling to maintain their current water infrastructure system, due to the lack of effective prediction tools at hand. The gap …

Development and application of new system reliability analysis methods for complex infrastructure systems
… new methods for stochastic damage detection of pipeline networks based on the MSR method. The methods allow for efficient uncertainty quantification of system quantities such as network flow measures and for updating the component damage probabilities based on post-disaster observations on …

Web-Based and Geospatially Enabled Tool for Water and Wastewater Pipeline Infrastructure Risk Management
Advanced pipeline risk management is contingent on accurately locating the buried pipelines, the milieu, and also the physical condition of the pipelines. The web-based and geospatially enabled tool presented in this thesis provides an improved way to assess the risks associated with the failure of …
