DRINKING WATER FLOW CONTROL AND MEASUREMENT RESOURCES

• Ensuring Water And Wastewater Resiliency During The Pandemic

  Remote monitoring helps keep employees safe while mitigating emergencies.

• Water Use Patterns Provide A Sense Of Normalcy

  From his perch in the control center at Denver Water, Phil Malone watches the city shift and stir, shaking off the night’s slumber.

• Optimizing Leak Detection With Virtual DMAs

  After experiencing significant real water losses in its distribution system and having difficulty locating the root causes, this large water authority in United Arab Emirates took a proactive approach by using real-time data to identify the source of leaks, reducing non-revenue water and gaining system intelligence to improve future operations, maintenance, and capital planning.

• Improve Your Plant Efficiency With Accurate Water And Wastewater Monitoring

  A West Coast wastewater management facility provides design, management, and maintenance of the sanitary sewer system for an entire county, including the conveyance system and treatment system. The wastewater treatment plant has been established for over 50 years and has the capacity to treat 41 million gallons of sanitary sewage per day (mgd).value chain. Siemens suggested that the customer try the Siemens HydroRanger 200 controller. The HydroRanger 200 uses proven, continuous, ultrasonic echo ranging technology to monitor water and wastewater of any consistency up to 15 m (50 ft) in depth.

• Remote Monitoring Provides Water Resilience During Crisis

  Managing three drinking water treatment facilities, multiple pump stations, more than 350 miles of pipelines, and a wastewater treatment facility is challenging even in normal conditions for a small city where agriculture is an economic driver and water demand can exceed 22 MGD.

• Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

  Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

• Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results

  When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.

• Sounding The Alarm On Silent Noncompliance

  Water and wastewater utility operators work diligently to operate within strict guidelines, ensuring their facilities are producing the best drinking water and highest quality effluent possible. Despite all their efforts, however, it can be easy to fall outside of regulatory compliance without even being aware. The key to avoiding problems like these is to understand how silent noncompliance can happen and knowing when to raise a red flag.

• Long Term Performance Of V-Cone Flow Meters

  This paper presents the results of 12 V-Cone DP Flow meters tested over a period of 17 years. Service applications for the V-Cones included natural gas as well as coke oven gas measurement, a dirty aggressive fluid that is problematic over long period of time for most flow meters. All testing was conducted in air by a 3rd party calibration laboratory, CEESI Colorado. Results will be presented for each of the meters over the 17 year span. Conclusions and recommendations will be made to the long term performance and recalibration intervals for the V-Cone flow meter.

• Advances In Flowmeter Technology

  This article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.
