  • Study: Fast, effective method removes 99% of BPA from water within 30 minutes

    Carnegie Mellon University chemist foresees lowering BPA exposure around the world Bisphenol A (BPA), a chemical used in the production of many plastics, is present in many water sources around the world. In a recently published study, chemists at Carnegie Mellon University conclude that certain catalysts called TAML activators, combined with hydrogen peroxide, can break down harmful ...

  • Managing Metallic Pipeline Networks In A Sustainable Manner

    In North America, the material and size of pipes that make up water and sewer networks range widely. Because these pipeline systems are so complex, it requires a strategic approach based on risk and real data for effective long-term management. Historically, however, it has been challenging to gather real data that can shape defensive capital decisions for an entire system. The assessment of ...

  • No Silver Bullet Technology For Pipeline Condition Assessment

    For utilities with large-diameter networks, waiting for failures to occur before repairing or replacing highly critical mains is not an option. With a large amount of buried water infrastructure reaching the end of its service life, operators have every incentive to take a proactive approach to asset management. Nowhere is this more critical than in busy urban centres. The fallout from an ...

  • Pure Technologies And Wrc Unite For Leak And Gas Pocket Survey On Critical Main For Irish Water And Cork County Council

    “The project was an excellent example of working in concert through every aspect of the planning stage, with everyone invested in a successful outcome…” The first time new parties come together to work on a pipeline inspection project, they face a lot of pressure to perform. The team must instill trust and understand each other to ensure the project goes off without a ...

  • Integrating water distribution system efficiency into the water conservation strategy for California: a Los Angeles perspective

    Improving water management in California requires a transition from imported to local water resources used efficiently. To assess this transitional capacity of water retailers in metropolitan Los Angeles County, we focused on a key water management metric: the water distribution efficiency. We traced the evolution of water loss reduction policy and practices globally with emphasis on ...

  • Adapting the IWA water balance to intermittent water supply and flat-rate tariffs without customer metering

    The International Water Association water balance is an approach applied worldwide for determining and analysing water losses in water distribution systems (WDS) up to the point of customer metering. Thus, water losses occurring ‘before’ a customer meter are at the expenses of the water utility while water lost or wasted ‘after’ the meter is paid for by the customer. This applies to systems ...

  • Investigating unaccounted for water and its components in Zomba City water supply system, Malawi

    This study assessed Unaccounted for Water (UFW) in Zomba City, Malawi in 2009 and quantified its real and apparent loss components. The study was carried out in the period January–May 2009 and focussed on three selected water supply zones (Airwing, Malonje and Sadzi) especially for determination of the components of non-revenue water (NRW). Field measurements of flow and utility records formed ...

  • Effect of reagents used during detection and quantification of Ascaris suum in environmental samples on egg viability

    Soil-transmitted helminths (STHs) are a major health concern globally. Infection is mostly through contact with contaminated water, food or soil. Therefore to break the cycle of viable transmission STH eggs must be quantitatively detected in the environment. The effect of different reagents on the viability of Ascaris suum eggs during laboratory detection and quantification was assessed and ...

  • Detect Leaks and Analyze Water Consumption with WaterSignal

    Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

  • Analysis of water balance and runoff generation in high latitude agricultural fields during mild and cold winters

    High-latitude conditions in northern Europe are characterised by short growing seasons (May–August) and long dormant seasons. Alternating mild and freezing conditions lead to variable snow accumulation–melt cycles affecting runoff generation, and consequently the loss of nutrients and sediments from agricultural fields. We assessed water balance in two subsurface drained clayey agricultural ...

  • How Not to Lose Cadmium While Measuring?

    Today cadmium finds a better usage than a hundred years ago. For example, metal cadmium plating is used for anticorrosion coatings that are more stable than zinc, nickel and tin-plated. Cadmium plating of steel parts gives greater resistance to corrosion, especially in sea water. About 20% of cadmium goes to the manufacture of cadmium electrodes used in ...

  • Evaluating the pressure-leakage behaviour of leaks in water pipes

    Much progress has been made over the last decade in understanding the behaviour of flow through leak openings with changes in water mains pressure. In particular it has been established that variations in leak areas with pressure is the main factor responsible for the range of leakage exponents observed in practice, and several numerical and experimental studies have investigated this ...

  • Component-holistic condition assessment of water distribution networks

    The work presented herein presents an expanded methodology for imprinting the condition of an urban water distribution network (WDN). Even though the majority of past research efforts related to WDNs deal with water mains (WMs), only a small part of the research studies have considered house connections (HCs) in the analysis and very few researchers have examined how the failure of pipe ...

  • Swabbing Water Lines – A Better Level of Water Awareness

    We know that biofilm is a tricky thing. It grows quickly, harbors bacteria, protects that bacteria from cleaning agents, and then releases those bacteria back into the water, potentially causing severe health issues. We clean and sanitize regularly to try to keep it controlled, but how can we know how much bacteria are actually inside the pipes? Doing a drip sample gives us just a vague idea. ...

  • Strategies for the electric regulation of pressure control valves

    In water distribution networks (WDNs), the classic pressure control valves (PCVs) are mechanical/hydraulic devices aimed at maintaining the target pressure just downstream or upstream of the PCV pipe, namely pressure reduction or sustaining valves. From a modelling standpoint, the major drawback of such local control is that classic PCVs may require target pressure varying over time with the ...

  • A novel freeze protection strategy for shallow buried sewer pipes: temperature modelling and field investigation

    The burial of sewer and water pipes below the maximum ground frost depth can be very costly and laborious in regions with cold winters. If a freeze protection measure is applied, the utility lines can be installed in a shallower trench to reduce the excavation needs. One freeze protection measure, so called heat tracing, consists of supplying heat along the pipes. In this work, the use of 4th ...

  • Pipeline Management Lessons: Old Isn’t Always Bad

    Underground pipelines are among the most valuable, yet neglected assets in the public arena. They provide essential services such as the supply of drinking water and collection of wastewater. Despite their critical importance, for decades many municipal utilities have operated under a “bury and forget” mentality – with little emphasis on long-term management of their aging ...

  • Guide to Removing Arsenic from Drinking Water

    It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be ...
