Improving the rapidity of responses to pipe burst in water distribution systems: a comparison of statistical process control methods
A pipe burst is a major water distribution system failure. Water escapes the network through the break increasing the total flow entering the network. These higher flows, in turn, increase the head losses in pipes and result in lower water pressures at customer taps. This study focuses on burst detection by seeking to identify anomalies in net system demand, pipe flow rates, and nodal pressure ...

Analysis of historic bursts and burst detection in water supply areas of different size
Pipe bursts in water distribution networks lead to water losses and a risk of damaging the urban environment. We studied hydraulic data and customer contact records of 44 real bursts for a better understanding of the phenomena. We found that most bursts were reported to the water company shortly after the beginning, and the negative consequences of the bursts were limited. However, smaller ...

Small leaks matter
In the final part of the leak detection series, we explain why locating small leaks is and important part of a water loss management strategy. To see the first post in the series that outlines the problem of water loss in North America, click here. Many leak detection programs have a mandate to save the most water and focus on locating and repairing large leaks in favor of small leaks. However, ...

Got deteriorating asbestos cement water mains?
Asbestos has come to be one of the most feared words and materials in the world. Yet, in the 1940s, 1950s and 1960s, more than 600,000 miles of asbestos cement– also called transite – used for its light weight, corrosion resistance, rigidity, ease of handling and installation was installed to handle water throughout the United States. Applications included potable water mains, storm ...

Hey, America: It’s time to talk about the price of water
Recent woes have drawn unprecedented attention to the worth of fresh, clean water. Can it change the way we pay for the world’s most undervalued resource? This summer, a 90-year-old water pipe burst under Sunset Boulevard in Los Angeles, sending a geyser 30 feet into the air and a flood of troubles over the UCLA campus. Raging water and mud trapped five people, swamped 1,000 cars and ...

Heuristic burst detection method using flow and pressure measurements
Pipe bursts in a drinking water distribution system lead to water losses, interruption of supply, and damage to streets and houses due to the uncontrolled water flow. To minimize the negative consequences of pipe bursts, an early detection is necessary. This paper describes a heuristic burst detection method, which continuously compares measured and expected values of water demands and ...

Study on relationships between climate-related covariates and pipe bursts using evolutionary-based modelling
Researchers extensively studied external loads since they are widely recognized as significant contributors to water pipe failures. Physical phenomena that affect pipe bursts, such as pipe-environment interactions, are very complex and only partially understood. This paper analyses the possible link between pipe bursts and climate-related factors. Many water utilities observed consistent ...

Case Study: Municipal Water Works Various Municipalities in Different Countries
Many Municipal Water Works and maintenance department engineers have been dealing with corrosion and scale which cause pipes to burst or leak (known as Physical Non-Revenue Water, or PNRW) lost is expressed as % of the volume per km of piping network per day. WATER SYSTEM CHALLENGES Typically, water is fed to every house or building or around the city (or municipality) through a network of ...

Resilient homes: worth the investment?
This case explores the economic viability of using an external generator and various other supplies to power a house in order to provide minimum power for sustaining living conditions, and contrasts these costs with the projected cost an insurance company would incur such as replacing and/or repairing burst pipes, spoiled food, and relocating a family to a hotel while repairs are completed. ...

Geostatistical techniques for approximate location of pipe burst events in water distribution systems
This paper focusses on the customisation and further enhancement of the recently developed data-driven methodology for the automated near real-time detection of pipe bursts and other (e.g. sensor faults) events at the district metered area (DMA) level. Assuming the availability of pressure/flow data from an increased number of sensors deployed in a DMA, the aim is to: (i) overcome the ...

Maintenance strategy for trunk mains: development and implementation of a high spatial resolution risk-based approach
This paper describes an enhanced concept for determining the right time and place for maintenance works (in this case rehabilitation and renewal), within the scope of a risk-based maintenance strategy for trunk mains, including a technical and economic risk assessment. The risks considered include damage caused by pipe failure (main burst) like revenue loss, third party property damage as well ...

Pipe burst diagnostics using evidence theory
This paper presents a decision support methodology aimed at assisting Water Distribution System (WDS) operators in the timely location of pipe bursts. This will enable them to react more systematically and promptly. The information gathered from various data sources to help locate where a pipe burst might have occurred is frequently conflicting and imperfect. The methodology developed in this ...

Transient and surge related pipe bursts, water loss and damage prevention
Pipe bursts as a result of transients and surges within a piping network are very common problems throughout the world. Not only are the maintenance costs of these repairs extremely expensive, but when you add in possible litigation for third party damages, combined with the potentially significant value (cost) of the lost water, you can quickly realize the significance of what may appear simply ...

GPR goes underground: Pipe Penetrating Radar
Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can be ...
