Drinking Water Measurement

  1. Are Your Pumps Running As Efficiently As Practical?

    In water and wastewater operations, optimizing energy use plays a huge role in cost efficiency, but how can you know if pumping equipment and other motors are running as efficiently as possible? Analytics systems that interpret performance from a variety of data points — pump curves, run time, flow rates, vibration, temperature, energy consumption, etc. — can quantify pump operation to keep performance efficiency on an upward track.

  2. Using Advanced Control Valves To Prevent Broken Mains And Reduce Water Loss

    The same scenario plays out daily at water utilities across the country. Water pressure begins to drop during morning hours as customers wake to prepare for their day. As demand decreases throughout the evening hours, system pressures creep up, hitting their highest levels in the early morning hours. This often leads to main breaks. Advanced control valves can be engineered to address this as well as many other problems faced by distribution system managers.

  3. Why More Utilities Are Investing In Remote Pressure Monitoring

    A car struck a fire hydrant in the middle of the night in California, creating a massive water leak. Even before first responders were notified, a pressure sensor sent a text alert to the water utility manager, who was able to dispatch a crew to the scene within minutes. What’s significant is that the utility responded long before receiving a call from emergency crews or an alert from its SCADA system installed in a nearby pump station.

  4. Smart Hydrants: A Proactive Approach To Main Breaks

    Fewer things are more aggravating to commuters than being told they’ll need to take a detour because of a water main break. Those breaks also leave water utilities with a hefty, unplanned bill. Smart fire hydrants, however, offer water managers the ability to get ahead of these problems by providing more insight than ever into their distribution systems.

  5. Improved Flow Measurement Through Multiple In-Pipe Readings

    A combination of water scarcity and the desire to provide exceptional service has driven water utility managers to be focused more than ever on acquiring accurate, real-time insight into their distribution systems. Operators face a natural hurdle, however, when using traditional center-line electromagnetic flow meters, which don’t account for velocities that vary across a pipe. Fortunately, a solution has emerged to address the issue.

  6. When Inches Count: Flow Metering In Constrained Spaces

    From offshore oil platforms that come with a hefty cost for every square foot to college campuses that rely on steam plants in cramped basements, flow metering is critical to many operations where space comes at a premium. The problem is that most flow metering technologies conflict with space limitations because of their substantial straight pipe run requirements. The good news is there is an alternative.

  7. Monitoring WTP Ozone Use With Maximum Cost-Efficiency

    The value of ozone as a disinfection agent is well understood in water treatment plants (WTPs). So too, is its cost. Getting maximum value from an ozone investment requires accurate measurement to assure proper disinfection levels without wasteful overuse of the precious gas. Here are multiple ways thermal dispersion mass flow meters deliver precise readings with lower installation and maintenance costs.

  8. Installing Granular Activated Carbon Today To Prevent Regulatory Issues In The Future

    In 2010, Shelby County Water Services (SCWS) was planning for the future. With new regulations on the horizon, SCWS determined that the Talladega/Shelby water treatment plant in Shelby County, AL, needed more effective removal of disinfection byproducts (DBPs). Specifically, the treatment plant needed help complying with the U.S. EPA’s new Stage 2 Disinfection Byproduct Rule (DBPR).

  9. Achieving Effective Microbiological Management In Distribution Systems

    Most distribution system water-quality problems can relate back to microorganisms growing as biofilms in the pipes. These biofilms can prompt chlorine residual degradation, corrosion, nitrification, THM formation, red or black water, and taste and odor problems as well as other issues. An effective microbiological control strategy combines the appropriate testing technologies and their use at optimal intervals.

  10. Thwarting Nitrification With A Proactive Approach

    A lack of real-time monitoring capabilities for treated water once it leaves the plant has many utilities scrambling to manage nitrification, which can appear abruptly and then be difficult to contain. Fortunately, advanced testing tools are available so water plant operators can take a proactive approach to the hazardous condition in their distribution systems.
