  • Leak behaviour in pressurized PVC pipes

    The correct definition of the leak law, i.e. the relationship between the leak outflow, the total head at the leak and other relevant parameters such as the pipe material, can seriously affect the accuracy of the numerical models used for the management of water distribution systems, either if they are used to forecast the leakage reduction by pressure management or to locate and size the leaks ...

  • Custom Pressurized Plastic Pipe Disposal Solution - Case Study

    Problem A large petro chemical company asked Waste Control Systems to solve a problem of pressurized plastic pipe after it had been tested for bursting strength. The QA test consisted of taking an eighteen inch section of pipe and welding caps on each end. One cap was solid and the other consisted of a fitting to allow air to be pumped into the section of pipe. A check valve was ...

  • Transient tests for locating and sizing illegal branches in pipe systems

    In pipe systems illegal branches can take away remarkable water resources with negative effects from both the economic and technical points of view. Difficulties in pointing out illegal branches by means of steady-state pressure and discharge measurements are mainly due to the fact that, of course, such systems are not active according to a regular time schedule. In this paper the possibility of ...

  • 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 ...

  • A new algorithm for real-time pressure control in water distribution networks

    This paper presents a new logic algorithm for real-time control of regulation valves in water distribution networks. This method entails identifying in real time the appropriate closure setting of regulation valves in order to reach and keep the desired piezometric height at the control node(s), by making use of measurements concerning both the piezometric height at the control node(s) and the ...

  • 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 ...

  • The challenges of creating a 250,000-pipe model for Miami-Dade

    Earth Tech has used InfoWorks WS to develop a record-breaking all-mains model of Miami-Dade’s water supply system in order to achieve an accurate representation of the entire distribution process. The new dynamic model covers the whole of the 250,000-pipe network, as well as all the associated facilities. 'One of the challenges was that we had to model the whole system - every single pipe,' says ...

  • 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 ...

  • Development of a sealing material and robot for automatic socket rehabilitation of grey cast iron pipes in drinking water supply systems

    The project DeWaLoP, led by Vienna Water, aims to develop a robot that is able to apply a sealing system to repair the joint sockets of pressure operating water pipes measuring about 1 m in diameter. To do this, a modification of the sealing material for inner surface application will be developed and a complex robot system will be designed to perform various tasks, such as inspecting, cleaning ...

  • Frankfort Electric and Water Plant Board Verifies Distress on Ductile Iron Pipe Using Electromagnetics

    Commercial introduction of ductile iron pipe (DIP) began in the mid-1950s and was established as the most frequently selected material of choice for ferrous pressure pipe by the early 1970s. Due to the widespread use of DIP during a large expansion of pipeline infrastructure in the 1970s, there are many thousands of miles of pressurized DIP in operation today. Water and wastewater utilities ...

  • Active leakage control in low pressures - It can be done!

    Leakage and PressureWater when leaving the pipe creates an ‘energy’ and it is this energy that is transferred through the water and the pipe wall by the means of acoustic sound. This acoustic sound depending on the material of the pipe work either dissipates over a long distance or is absorbed very quickly into the pipe wall. The effect being that for metallic or hard walled pipes the sound ...


  • Field Performance Testing for Pipeline Pumps

    Significant energy savings can be achieved by optimizing pump operating efficiency. Measuring the exact pump performance with crude oil under realistic conditions in the field is the first step towards improving the pump efficiency in the future. About 20 billion barrels of crude oil were transported through pipelines in 2015. Around the world, there are over one million kilometers of ...

  • Advanced Enviro-Septic™ Systems Achieve Even Distribution without Pressure Dosing

    Abstract: Advanced Enviro-Septic™ Systems (AES) do not use pressure distribution. Pumps are used only if necessary to gain elevation to the treatment field. Pressure distribution has the potential to disrupt the settling of solids within the pipe. Testing has confirmed that AES achieves even distribution throughout the system naturally, through the development of a controlled bacterial ...
