  • What makes high-risk pipelines deteriorate to a state of failure?

    According to AWWA's 2016 Benchmarking Survey, the average water and wastewater utility has seven breaks per 100 miles of piping every year. Tip-top systems experience just four breaks in that distance, while those at the bottom have 18. While it’s interesting to note the difference in break rates, it’s unfair ...

  • Articulated Concrete Blocks Provide Much Needed Protection for Your Pipeline

    One of the many ways that articulated concrete blocks can protect pipelines is by adding structural stability in areas that are particularly prone to erosion. This erosion is not the only type of hazard posed to your pipeline, though, and if you don’t have the proper protection in place, your pipeline could be susceptible to deterioration at the hands of these other threats as well: ...

  • Advantages of Using Flow Meters to Reduce Pressure Drop

    Plant operators rely on plant air pressures to maintain properly working equipment and systems. One of the most common problems affecting processing plants that utilize compressed air systems is the ability to maintain reliable air pressure throughout the distribution system. Insufficient air pressures may be due to undersized distribution piping, but it’s more commonly found that the cause ...

  • Have You Missed a Valve Checkup?

    Let’s face it: Few people enjoy going to the doctor for routine exams — but it’s important. Routine visits help make sure you’re in good shape, and highlight things you can do to be even healthier. As you schedule your annual trip to your physician, don’t forget that valves need checkups, too. In fact, control valves need a checkup every 12 weeks. In our latest ...

  • Sulfide emissions in sewer networks: focus on liquid to gas mass transfer coefficient

    H2S emission dynamics in sewers are conditioned by the mass transfer coefficient at the interface. This work aims at measuring the variation of the mass transfer coefficient with the hydraulic characteristics, with the objective of estimating H2S emission in gravity pipes, and collecting data to establish models independent of the system geometry. The ratio between the H2S and ...

  • A comparison of three dual drainage models: shallow water vs local inertial vs diffusive wave

    In this study we compared three overland flow models, a full dynamic model (shallow water equation), a local inertial equations model (gravity wave model), and a diffusive wave model (parallel diffusive wave model). The three models are coupled with the same full dynamic sewer network model (SIPSON). We adopted the volume exchange between sewer and overland flow models, and the hydraulic head ...

  • Flow Rate Measurement in Full Pipes Using the Transit Time Method

    Particularly in large diameters the relevance of water volume measurement is growing. The challenge with cooling water or fresh water processes is to generate accurate flow recordings or to document and to control individual consumptions and withdrawal quantities. Flow detection, however, particularly in large diameters is highly demanding. In such cases the transit time measurement thanks to its ...

  • Leak-before-break in cast iron mains: a failure analysis of a catastrophic pipe burst on Harris Street, Sydney

    This article analyses the failure of a 500 mm-diameter cast iron (CI) water pipe that catastrophically fractured in Sydney in 2013. According to metallurgical analysis and finite element simulation, a longitudinal pre-existing crack initiated from the adjacent bell-joint and eventually propagated to a critical length in the pipe barrel over a certain period. There was evidence of leakage prior ...
