  • 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 ...

  • Eclox Rural Water Association Helps Assure Water Security Statewide with Rapid Response Water Test Kit

    The ability to rapidly monitor the quality of U.S. source water for contamination has never been more important than it is in today’s security-sensitive environment. The Delaware Rural Water Association (DRWA), located in Milford, Del., is a non-profit trade organization, one of 47 state affiliate members of the National Rural Water Association. The mission of the DRWA is to improve the quality ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • GOOD NEWS FOR DRINKING WATER Independent Test Lab Evaluates Instrumentation forDetecting Radiation in Drinking Water

    Since 9/11 and there are still holes in security of the nation’s infrastructure, particularly for drinking water. This security deficit is currently being addressed in some community water systems with water monitoring instruments. In the 90s the EPA developed a wish list for monitoring contaminants in drinking water. Since that time biological and chemical contaminants have been identified ...

  • Who used your water yesterday?

    The answer to the question above boils down to numbers in the final analysis. With more than half of the world's population already based in urban areas the additional demand for core services such as water is overtaxing capacities for water supply and disposal in many of the world's larger cities. And the problem is only going to get worse. The proportion of the world's population that will be ...

  • The Need for a Total View of Water Networks

    The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the ...

  • Case study - Flood water protection in the city of Buenos Aires

    The Arroyo Mendrano is the second largest channeled stream of water running through Buenos Aires. In case of heavy rainfalls it overflows its banks and causes considerable material damage. When the retention basin which had been especially built to collect large quantities of water during strong precipitation events also overflowed, the government decided to have an alarm-system installed to ...

  • Ultrasonic depth sensor to measure water levels

    The Dutch algae control company LG Sonic introduced an ultrasonic depth sensor to give the customers real-time insight in the water levels which allows them to adequately deal with water level fluctuations. Reservoirs used for industrial processes or the production of drinking water often deal with strong water level fluctuations. Due to events of high demand and evaporation, water levels in ...

  • 5 ways to conserve water this winter

    Water conservation is something we harp on during the summertime, but what about during the winter? When the irrigation systems shut down, it’s easy to put conservation on the back burner while indoor water waste continues to occur. According to the U.S. Geological Survey, the average person uses 80-100 gallons per day for everything from cooking, to showering and flushing the ...

  • Dynamic soft sensors for detecting factors affecting turbidity in drinking water

    Effective monitoring of water quality is critical for water safety. In particular, online monitoring based on modeling is useful in several applications such as process assessment, hazardous event detection or common fault diagnostics in the water processes. Soft sensors have lately established themselves as a good alternative for different tasks of process control such as the acquisition of ...

  • Water Loss management will be critical to climate change adaptation

    Water loss management is one of the most important issues facing water suppliers around the world. The Sustainable Development Goals have made poverty alleviation and access to safe drinking water a political priority. Targets on providing safe drinking water as a basic human right aim to ensure everyone can access a safe water supply. Unfortunately, the reality is that many of the most ...

  • Risk assessment and water safety plan: case study in Beijing, China

    Two typical rural water utilities in Beijing, China were chosen to describe the principles and applications of water safety plans (WSP), to provide a methodological guide for the actual application and improve the quality of rural drinking water quality, and to establish an appropriate method for WSP applied in rural water supply. Hazards and hazardous events were identified and risk assessment ...

  • Practical applications of quantitative microbial risk assessment (QMRA) for water safety plans

    The absence of indicator organisms in drinking water does not provide sufficient guarantee for microbial safety. Therefore the water utilities are implementing water safety plans (WSP) to safeguard drinking water quality. Quantitative microbial risk assessment (QMRA) can be used to provide objective quantitative input for the WSP. This study presents several applications of treatment modelling in ...

  • Unsealed tubewells lead to increased fecal contamination of drinking water

    Bangladesh is underlain by shallow aquifers in which millions of drinking water wells are emplaced without annular seals. Fecal contamination has been widely detected in private tubewells. To evaluate the impact of well construction on microbial water quality 35 private tubewells (11 with intact cement platforms, 19 without) and 17 monitoring wells (11 with the annulus sealed with cement, six ...

  • Disinfection by-products in drinking water – a case study on Calgary, Alberta, Canada

    Disinfection by-products (DBPs) have been monitored in Calgary's drinking water for approximately 15 years. The variability of the DBPs has typically exhibited similar patterns over the period of monitoring. Due to the nature of the surface waters supplying the water treatment plants, the level of DBPs was largely influenced by surface runoff events where the level of natural organic matter (NOM) ...
