  • 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 ...

  • Pipeline Replacement without System Shutdown

    ABSTRACT According to one estimate there is over 4.2 billion feet of wastewater pipeline in the United States. The nation’s sanitary sewer system is increasing in size and the existing infrastructure is aging. Currently, there are almost 20,000 municipal collection systems building and maintaining these critical pipelines. A good portion of the pipe conduit is under attack by one or more of ...

  • Pipeline Zooming for a Comprehensive Infrastructure Survey.

    Time, budget and resources often keep a municipality from maintaining comprehensive, up-to-date information on water and sewer pipeline conditions. Without a complete understanding of their infrastructures, municipal supervisors cannot properly prioritize and schedule maintenance activities. As a result, emergencies—backups, collapses, and overflows—happen unexpectedly, and must be dealt with on ...

  • Surviving the Jackson Drive interconnect pipeline project

    The San Diego County Water Authority got the call at midnight on May 16, 2006. One of themajor water delivery pipelines in Mission Trails Regional Park in San Diego had burst, resulting in millions of gallons of water rushing through the park. It was over the next several hours that the Water Authority’s community outreach began. Within days the project was declared an emergency and the Water ...

  • Advanced criticality assessment method for sewer pipeline assets

    For effective management of water and wastewater infrastructure, the United States Environmental Protection Agency (US-EPA) has long emphasized the significant role of risk in prioritizing and optimizing asset management decisions. High risk assets are defined as assets with a high probability of failure (e.g. soon to fail, old, poor condition) and high consequences of failure (e.g. ...

  • San Diego County Water Authority Manages Steel Pipelines

    Utilities across the country are experiencing an increased rate of pipeline failures. In addition to problems precipitated by an aging water infrastructure, a lagging economy is affecting large-scale capital projects needed for repairing, replacing, and improving infrastructure. With funding gap estimates ranging between $200 billion and $1 trillion over the next 20 years, utilities must find ...

  • Metropolitana milanese reduces water loss on critical steel pipeline

    Assessing the condition of buried water infrastructure can yield a variety of outcomes that are difficult to predict. Sometimes, they even seem random. The common belief that the age of a pipe determines its condition is rarely correct – in many cases, a newer main can be in worse condition than one twice or three times as old. Instead, operational, environmental and installation factors ...

  • What’s New? Maximizing The Life Of Aging Metallic Pipelines With Modern In-Line Technology

    Maximizing the life of aging pipelines has long been a challenge in North America. Owners of large diameter water and wastewater infrastructure face particular condition assessment challenges, owing to factors such as financial constraints, environmental concerns and access restrictions, which compound the problem. While desktop studies can help identify pipes with a likelihood and consequence of ...

  • 1700 miles of the keystone Xl Pipeline: A state, federal and international regulatory concern

    Regulatory compliance at the state and federal level grows infinitely more complex when the laws and regulations of six U.S. states, U.S. federal regulations, and the Canadian regulatory regime are intertwined.  TransCanada’s proposed Keystone XL Pipeline, currently awaiting approval from the U.S.  Department of State, is gaining as much attention for its regulatory ...

  • Estimating burst probability of water pipelines with a competing hazard model

    Because pipeline systems represent more than 80% of the total asset value of water-distribution systems, their management is an important issue for water utilities. A pipeline deteriorates over time after installation and, along with the deterioration, pipe bursts can occur as various types, and the choice of a maintenance and repair strategy will depend on the burst types. It is therefore ...

  • Pipeline infrastructure renewal at Miami-Dade Water & Sewer Department

    Abstract Various governmental, professional and private studies have shown that the replacement costs of underground pipeline infrastructure is excessive and that best practice approaches for infrastructure risk management promote condition assessment programs to understand the actual condition of individual pipe sections in order to best allocate limited capital replacement and ...
