  • Development of wastewater pipe performance index and performance prediction model

    Prediction/deterioration modelling is a crucial step in assessing the remaining service life for strategic management planning. Sound pipe performance evaluation models are essential for accurately predicting future performance. There is a lack of a performance evaluation tool which takes into consideration different factors such as pipe characteristics, internal and external environmental ...

  • Predicting wastewater temperatures in sewer pipes using abductive network models

    A predictive modelling technique was employed to estimate wastewater temperatures in sewer pipes. The simplicity of abductive predictive models attracts large numbers of users due to their minimal computation time and limited number of measurable input parameters. Data measured from five sewer pipes over a period of 12 months provide 33,900 training entries and 39,000 evaluation entries to ...

  • Applications of Pipe Penetrating Radar for Advanced Pipe Condition Assessments: the Clark Regional Wastewater District (WA) Case Study

    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 non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids outside ...

  • Combined application of Pipe Penetrating Radar and LIDAR for large diameter pipe inspection

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in./450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. Light Detection and Ranging (LIDAR) has become an accepted method for ...

  • Installation of Large Diameter Buried Pipes

    The ProblemThere is an ongoing need to provide designers, specifiers, engineers, consultants and students an overview and general understanding on the proper installation and rehabilitation of buried municipal and industrial pipelines to provide a long-lasting wastewater and potable water infrastructure that will serve future generations. Goals and ObjectiveMost buried ...

  • A comparison of trenchless pipe bursting vs. conventional open cut methods for water and wastewater transmission mains

    ABSTRACT Over the last 15 years, new advances in trenchless technologies have emerged across Europe and are finding their way into the United States. One of the fastest growing methods involves pipe bursting of existing pipe and replacement with new larger diameter pipe. The existing pipe is shattered into small pieces and pushed into the surrounding soil. A new pipe of like or larger size is ...

  • Investigating nitrogen removal using simultaneous nitrification-denitrification in transferring wastewater through collection networks with small-diameter pipes

    This study evaluates the removal of nitrogen compounds from wastewater in modified, small diameter gravity slope (SDGS) pipes during its conveyance. A 13-meter long, closed loop, wastewater collection network was designed and built at laboratory scale. The modified SDGS consists of Polyvinyl Chloride (PVC) tubes with perforated plastic netting fixed to the inner surfaces, to enhance biofilm ...

  • In-pipe monitors turn dreams into reality

    In-pipe monitors turn dreams into reality The quality of tap water has improved enormously in recent decades, but for largely technological reasons, until recently, knowledge of water quality between the treatment works and the tap has been an almost impossible dream for water treatment and distribution network managers. In this article, Jo Cooper, Product Specialist at Intellitect Water, will ...

  • Wastewater Treatment in Sri Lanka

    JaEla and Ratmalana wastewater treatment. Recently Colombo National Water Supply & Drainage Board decided to collect and treat the combined (industrial and domestic) wastewater at both areas before it is being discharged into the receiving waters. New sewer systems and two wastewater treatment plants will therefore be constructed. The target treatment plant sizes are 82,000 ...

  • Wastewater Recycling: Radiator Warehouse

     Radiator Warehouse is a small company that has been able to compete and grow through innovation and a commitment to cleaner production. After surveying available technology for recycling water and reducing chemicals, it decided to develop its own, much simpler system at a cost of only $10,000. This was not only cheaper than available overseas technologies, but was also just half the cost of ...


  • Wastewater Treatment Works

    Margate and Broadstairs, two of the principal towns in northeastern Kent, attract thousands of visitors each summer to enjoy the beaches and countryside within easy reach of London. Such popularity comes with a cost. The infrastructure serving the area needs to be developed to keep pace with the rising population and the requirements of new UK and European Union legislation. With the ...

  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • Better ways to deal with wastewater

    A city’s wastewater treatment infrastructure is part of the groundwork for the organization of an entire community. This is one of the most costly endeavors for the community and using a centralized system is often not an environmental benefit. There is conclusive evidence centralized sewer collection systems are leaking and causing treatment plant overflows during strong wet weather ...

  • Measuring Wastewater Below Ground

    Measuring wastewater is one of the most difficult water management tasks that exists. While some wastewater flows are easy to access, others are very hard to measure because they are in open channel conditions and are below grade. If you need to measure below ground wastewater flow, there are a few factors that you need to consider to help you choose the right tool for the job. With a ...

  • Water and wastewater projects in Jordan

    About 70% of Jordan has an annual rainfall of less then 100 mm. The population and water demand have increased during the last years and the groundwater resources are in danger of drying out. As the population continuous to grow it is necessary to find new resources to meet future demands of water for municipal, industrial and irrigation purposes. The two projects, As-Samra and Disi, aims to ...
