  • Analysis of flushing-path effects in water-distribution networks

    The unidirectional and conventional flushing methods are compared in this study and the water amount and flow velocity at junctions within an EPANET water distribution network are compared. In the unidirectional method, the necessary flow and water pressure for the minimum flow velocity for flushing become greater when pipe diameter exceeds a certain value. Therefore, the maximum length of ...

  • Water Main / Fire Line Rehabilitation

    Problem Dirty brown water and poor water flow were the first clues that a mid-Atlantic commercial property owner had a problem. Then the owner was put on notice by the local fire department that the water supply lines were no longer meeting the required flow requirements. Four hydrants on the owner’s property were flowing between 200 to 300 gallons per minute due to heavy corrosion-induced ...

  • POE sediment filtration — your first line of defense

    Around the country, our aging water delivery infrastructure is coated with sediment and scale from a century or more of buildup. Those same tuberculated pipes are constantly challenged by daily tie-ins, repairs, flow tests and fire hydrant use in most cities and towns. The result is that drinking water that left the municipal treatment plant at top quality arrives in users’ glasses — or in their ...

  • 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 ...

  • Application of unidirectional flushing in water distribution pipes

    In this study unidirectional flushing (UDF) was conducted to improve the effectiveness of deposit removal from internal pipe walls and to provide information on pipe networks to enable operators to implement flushing in field. Four ductile cast iron pipes with epoxy-lined and cement-lined were selected for the practice of UDF. Water pressure was measured using a data logger equipped with a ...

  • Case study - Germany/Eislingen - Permanent leakage monitoring is the fastest way to reduce leakage

    The town of Eislingen in Southern Germany has practiced Active Leakage Control for many years with a team of two equipped with a ground microphone and correlator who drive around in a van searching for leaks. As many of the pipes are one hundred years they had a good success rate often finding leaks. With two hundred and forty kilometers in the network, there is a large area for one team to cover ...

  • What Causes Water Main Leaks?

    The number one cause of water leaks today and moving into the future will be the aging infrastructure. “A large part of the US public water system dates back to the years shortly after World War II, therefore, a significant amount of buried infrastructure is at or very near the end of its useful life.” – Qureshi & Shah, Journal AWWA. When aging infrastructure is combined ...

  • Healthy Control Valves

    A simple maintenance routine can help ensure trouble-free valve operation. Whether the control valve in your system is the first one that has required maintenance or if you are experienced with maintaining multiple valves in your system, some simple guidelines can help keep them operating at optimal performance. Physically checking all valves at least every 12 weeks is important, assuming that ...
