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 ...

  • City of Portland Bureau of Environmental Services Deep Tunnels for Combined Sewer Overflow Storage and Transport – Portland, Oregon

    BACKGROUNDThe Bureau of Environmental Services (BES) of Portland, Oregon, began a major program to mitigate combined sewer overflows (CSOs) into the Willamette River and Columbia Slough in 1991. The Program was organized into three major phases: Cornerstone projects to reduce stormwater entering the combined sewer system, ...

  • Assessment on inflow and infiltration in sewerage systems of Kuantan, Pahang

    Inflow and infiltration are important aspects of sewerage systems that need to be considered during the design stage and constantly monitored once the sewerage system is in operation. The aim of this research is to analyse the relationship of rainfall as well as inflow infiltration with sewage flow patterns through data collected from fieldwork. Three sewer pipelines were selected at the ...

  • Serviceability assessment and sensitivity analysis of cast iron water pipes under time-dependent deterioration using stochastic approaches

    Determination of the depth of the corrosion pit is essential to predict the serviceability of corrosion affected pipes and to instigate maintenance and repairs for the pipeline system. In this paper, a reliability-based methodology for serviceability assessment of corrosion affected pipes is presented. The depth of corrosion pit is considered as the critical parameter that causes ...

  • New York City Chooses Ductile Iron Pipe For First Pipe Bursting Project

    When the City of New York Department of Design and Construction (DDC) determines a pipeline needs to be installed, any private utility using the City’s right-of-way, e.g. ConEd, Cable Vision, Key Span and Verizon, is responsible for the cost of relocating and supporting, if possible, any conflicting lines prior to or during construction. This cost can be extremely high since utility corridors are ...

  • Who, What, Where, and Most Importantly Why? (Women Wastewater Engineers in Today’s Workforce)

    ABSTRACTThroughout the United States today, women are designing wastewater treatment plants, pump stations, and sewer pipelines. Women are involved in every aspect of wastewater design, including specification preparation, bidding, and construction oversight. In a profession once considered “undesirable” to women, many are now making significant contributions to the industry and helping overcome ...

  • Getting ready for a larger panama canal - assessing a critical large diameter force main

    Abstract Opened in 1905, the Government Cut is a manmade shipping channel between Miami Beach and Fisher Island, which allows better access to the Port of Miami in Miami, Florida.

  • Robot Device for Pipe Inspection - Case Study

    In 2005, Pure Technologies (Pure), a provider of various structural monitoring and leak-detection technologies, set about to develop a pipeline assessment tool that could monitor and report on the condition of pre-stressed concrete cylinder pipes (PCCP) utilized in municipal water and sewer systems. The tool’s competitive advantage would be accurate assessment decoupled from the need to ...

  • Installation of Large Diameter Buried Pipes

  • Quantitative pipe condition assessment with Pipe Penetrating Radar

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-ferrous (reinforced concrete, vitrified clay, PVC, HDPE, etc.) pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids ...
