  • 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 ...

  • Determination of Flow Rates in part-filled Applications using the Radar Method

    Introduction The radar measurement method plays an increasingly important role in the water and wastewater field. This is particularly reflected by the "Metering outside of the medium" trend. Flow measurement using radar which enables contactless measurements thus becomes a major focal point. It features a wide range of applications and hence is useful as permanent measurement system for ...

  • Diagnosis of pipe systems by the SLE: first results

    In this study, an algorithm is presented for pipe system diagnosis. The algorithm is the Successive Linear Estimator (SLE) previously used in groundwater hydrology to estimate the hydraulic proprieties of soils. The SLE is an iterative cokriging-like technique which provides statistically the best unbiased estimates and quantifies the associated uncertainty. In this paper the algorithm has been ...

  • Biocorrosion in drinking water pipes

    Copper is widely used in drinking water distribution systems due to its relatively low cost and favorable mechanical properties. However, copper corrosion may generate copper concentrations exceeding the thresholds prescribed by international drinking water standards. In-situ measurements performed in an actual system found that the copper mass released under flowing water conditions (pipe ...

  • Quadratic approximations for pipe friction

    This paper develops quadratic approximations to the classical models of Darcy–Weisbach and Hazen–Williams for frictional head loss in water pipes. Key elements of the technique are selecting the approximation domain and minimizing the relative error. A comparison for individual pipes over a range of diameter, roughness, and Reynolds number showed that the approximation provides ...

  • Intake Pipe Repair

    Major problems can cause catastrophic damages to a facility’s operations. The accumulative cost of: repairs, labor, and downtime can add up. This 24 inch diameter intake pipe, located at a U.S. Power Plant, was leaking above the ground just below the disc valve. The plant’s maintenance engineers needed a proven, reliable and economical solution to fix this ...

  • Preventing & Thawing Frozen Pipes

    A “how-to” guide on preventing and thawing frozen pipes. As temperatures drop below freezing around the country, it’s important to be informed of the cold weather’s effect on your water pipes. When temperatures are below freezing, pipes in unheated areas are subject to freezing causing messy, and often expensive issues. Just one burst pipe running at 4-8 ...

  • Measuring Strains in Buried Flexible Pipes

    A field measurement system is described for determining strains in buried flexible pipes. The microprocessor-based system obtains data that is subsequently analyzed on minicomputers or mainframe machines. The field system is also capable of analyzing the data using its own microprocessor provided that a graphics terminal is available. Numerical algorithms for analyzing the data are developed, and ...

  • Characteristics of pipe-scale in the pipes of an urban drinking water distribution system in eastern China

    Pipes that carry drinking water have gradually aged. Events occurring with increasing frequency, such as substandard water quality in residential taps, red water, and black water, reveal the deterioration of the chemical stability of a drinking water distribution system (DWDS). Pipes in the DWDS serving City S, located in eastern China, were sampled to analyze the concentration and ...

  • Rainstore3 – Alternative to Pipe and Open Drains

    Open drains in Malaysia perform the same function as pipe in many other parts of the world – collect and convey surface runoff from pavement and landscaped areas to nearby streams and rivers. When these open drains encounter a structure (road or building) then they must interface with a pipe or culvert type of conveyance product. Rainstore3 can be used for conveyance, as well as storage ...

  • Risk management for water supply pipes

    In this paper, the risk of water supply systems as a combination of hydraulic analyses (consequence) and failure probability of pipelines based on the actual condition is discussed. On the one hand, a stepwise closing of pipelines calculates the influence on customer's supply which represents the importance of a pipe. On the other hand, based on existing failure statistics, age and material ...

  • Plugging `hot` pipes in extreme environments

    Some of the world's most intricate infrastructure is found in power plants, chemical plants, refineries, and other factories that use and combine industrial chemicals. The piping for fuel, chemical transport, water supply, and cooling needs is typically very complex and subject to high temperatures and pressures. And since plants are harsh environments, it's a given that piping needs regular ...

  • On the prediction of underground water pipe failures: zero inflation and pipe-specific effects

    The prediction of pipe failures in water distribution systems is an essential planning tool for water companies. Previous methods focus on the prediction of either future failure numbers or aspects of pipe condition. However, most of these only predict at the level of large pipe groups (of similar characteristics) and often cannot provide uncertainty bounds. Here, a new statistical method is ...
