Application of survival analysis modeling in water pipelines failure in Cape Town
The statistical modelling of water pipelines failure has been widely adopted by water authorities in their pursuit to proactively manage their aging water distribution systems. In this thesis failures of the 100 mm FC pipes in Cape Town City have been modelled by using survival analysis techniques. …

A Framework for Holistic Life Cycle Cost Analysis for Drinking Water Pipelines
… economic life cycle cost analysis. The drinking water industry is right now lacking a reliable cost data structure which will ensure that all the utilities capture the same set of cost data. Also, models and tools currently available in the academia and industry are purely deterministic in nature …

Identifying the factors that affect the provision of water to households in the Free State Province
The deterioration of water infrastructure leads to a reduction in economic growth and poor health for the citizens. Decision makers in local government prefer to prioritise above ground infrastructure and neglect critical underground infrastructure issues such as maintenance of water pipelines. As …

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 …

A real-time robotic platform for pipeline inspection
Pipelines are used around the world to transport raw materials, waste products, and, critically, potable water. Protecting the pipes from the elements often leaves them difficult to inspect for leaks and corrosion, which can cause costly, even deadly, damage. Currently, typical inspection methods …

Development of Predictability and Condition Assessability Indices for PCCP Water Mains
The condition of water and wastewater pipelines has been deteriorating with time and since this infrastructure is out-of-sight, the assessment has been neglected over the years. The advancement of technology in various fields has provided pathway for development of several technologies for …

Robot design for leak detection in water-pipe systems
Leaks are major problem that occur in the water pipelines all around the world. Several reports indicate loss of around 20 to 30 percent of water in the distribution of water through water pipe systems. Such loss of water represents critical waste of valuable resources, especially in countries such …

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) …

Transpiration Electrokinetic Power Generation and Zinc Ion Battery for Autonomous Leak Detection
Every year $6 billion worth of water is lost in residential homes caused by undetected leaks creating nearly $20 billion in property damage annually in the U.S alone. These leaks also raise environmental concerns due to energy consumption in water treatment plants and declining freshwater sources. …
