  • Water Level Measurements-Part 1

    Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

  • Reaching economic leakage level through pressure management

    High non-revenue water (NRW) values as a percentage of system input volume form a serious problem that many water utilities worldwide have to confront nowadays. There are ways to mitigate the effect by adopting strategies with short- and long-term results. Water pressure management (PM) is one of the most efficient and effective NRW reduction strategies. To calculate pressure management of ...

  • European waters - assessment of status and pressures

    EEA 2012 'State of Europe's water' assessments 2012 is the European year of water in which the European Commission published its 'Blueprint to safeguard Europe's waters' (referred to hereafter as the Blueprint) comprising reviews of the Water Framework Directive (WFD) (2000/60/EC), water scarcity and drought and adaptation to climate change policies. To accompany and inform the blueprint, ...

  • Determination of diurnal water level fluctuations in headwaters

    The aim of this paper is to study diurnal fluctuations of the water level in streams draining headwaters and to identify the controlling factors. The fieldwork was carried out in the Gryżynka River catchment, western Poland. The water levels of three streams draining into the headwaters via a group of springs were monitored in the years 2011–2014. Changes in the water pressure and water ...

  • The joint effect of water price changes and pressure management, at the economic annual real losses level, on the system input volume of a water distribution system

    This study attempts to examine the factors affecting the residential water demand level in the city of Kozani in Greece. Based on an 8-year (2005–12) detailed sample of residential water demand panel data, the values of the water price (WP) elasticity of residential demand are identified, and the influence of socio-economic and demographic factors and climate conditions on water-use levels and ...

  • Intermittent operation of low pressure UF membranes for sewage reuse at household level

    A household-scale wastewater treatment system was operated with domestic sewage. The system could recover gardening/irrigation water from raw sewage or secondary effluent by low pressure ultrafiltration (UF). The UF membranes (surface area = 3.5 m2, pore size = 0.04 μm) were operated at constant transmembrane pressure (0.13 bar). The proposed technology was examined for ...

  • Water Pressure Measurement with Time Domain Reflectometry Cables

    Attributes of the remote measurement of piezometric water pressure and water level with time domain reflectometry (TDR) techniques are investigated. The evaluation includes a two-wire system for unusually small riser tubes as well as parallel wire and air-filled or hollow coaxial cable for typical installations. Comparison of TDR cable and commercial pressure transducer technology shows coaxial ...

  • A Comparison between Steam and Hot Water Pressure Washers

    Steam pressure washer machines are a gradual extension of hot water pressure washers. The main difference lies in the output temperature. While steam pressure cleaners provide an output of 330 degrees Fahrenheit, hot water machines offer an output pressure of 210 degrees Fahrenheit only. The other important specifications, such as output pressure and technologies present, do not change much ...

  • Evaluating changes in water institutions: methodological issues at the micro and meso levels

    ABSTRACT Institutions (formal rules) governing water allocation and use are often critical to a nation's development and prosperity. It is often necessary to change water institutions as economic, physical and political circumstance change. In this paper, a framework is presented to help understand the potential and need for change in water institutions. The pressure for institutional change ...

  • Benefits of Hot Water Pressure Washers for Wet Steam Cleaning

    Hot pressure washers have revolutionized commercial cleaning processes. Roads, gas stations, boats, cars, airplanes, factory floors, basements, kitchens and similar areas can now be cleaned more easily than before. No longer are contractors depending exclusively on tedious methods such as trailers with rotary brushes to handle layers of grease and grime. Hot water pressure washers hold many ...

  • Tips to Get the Best Out of Hot Water Pressure Washers

    You may have heard people complaining about hot water pressure washers. Something does not work, some parts get damaged, or it uses a lot more gas than anticipated, and so on. However, thinking rationally about it, you will realize that the problem is not with the machine, but that the machine itself is not equipped for the right cleaning applications. A machine is designed for certain uses. In ...

  • Versatile Hot Water Pressure Washing Machines for Industrial Cleaning

    Hot water pressure washers are ideal dual purpose machines, as they can use hot water as well as non-heated water for cleaning different surfaces. Having this choice is important, because some applications do not require the additional cleaning power of hot water. Some surfaces may even become damaged by very high temperatures. On the other hand, the contractor will often come across cleaning ...

  • Introducing pressure and number of connections into water loss indicators for French drinking water supply networks

    In France, the system of performance indicators defined within the relevant regulations does not include indicators relating to pressure, or the number of connections. So, Irstea and Veolia Water decided to create a new system of water loss indicators designed for use in France and that would take into account these parameters. The study was initially carried out at District Metered Area (DMA) ...
