Regulation Updates For Utility Management

  1. 3 Ways Hach Has Made CL17 Chlorine Monitoring Even More Efficient

    For more than 25 years, the Hach CL17 Colorimetric Chlorine Analyzer has been a well-established choice for continuous monitoring of free and total residual chlorine. Now, added connectivity, diagnostic, and maintenance features are making its trusted reliability and data accuracy more readily accessible and easier to manage than ever before. Here is how the experience of current users is being improved.

  2. Striking An Ideal Balance In WTP/WWTP Chlorine Dosing

    For managing chlorine feed rates, automated chlorine analysis has always offered advantages over manual grab samples and feed adjustments. Today, chlorine analyzers connected to cloud-based systems for integrated instrument, data, and process management are bringing new continual-sampling insights to water and wastewater treatment plants (WTPs/WWTPs).

  3. Leveraging Connectivity For Improved Chlorine Analyzer Performance

    While accurate instrument readings are important to water treatment plant (WTP) and wastewater treatment plant (WWTP) operators, having deeper understanding of plant operations is even more valuable. Here’s how intelligent networking capabilities are giving plant operators better understanding and control over their processes by enhancing instrumentation operation, data sharing, and maintenance management.

  4. Evolution Of Pipeline Leak Detection

    As the sheer number of pipelines crisscrossing the country continues to increase, there is an urgent need to ensure pipeline infrastructure safety. The age of many of the pipelines and the number of different products flowing makes this a challenging prospect. Now, new technology has been developed that meets the need for reliable protection that complies with regulatory requirements while eliminating false alarms.

  5. New Elevation Data Triple Estimates Of Global Vulnerability To Sea-Level Rise And Coastal Flooding

    Most estimates of global mean sea-level rise this century fall below 2 m. This quantity is comparable to the positive vertical bias of the principle digital elevation model (DEM) used to assess global and national population exposures to extreme coastal water levels, NASA’s SRTM. CoastalDEM is a new DEM utilizing neural networks to reduce SRTM error. Here we show — employing CoastalDEM — that 190 M people currently occupy global land below projected high tide lines for 2100 under low carbon emissions, up from 110 M today, for a median increase of 80 M.

  6. Managing Disaster In An Age Of Climate Change

    South Africa’s towns and cities could be rendered more resilient to natural disasters if municipalities understand the likely impacts of climate change and build these impacts into their disaster management strategies for the future.

  7. Plastic Flow Meters Reduce Weight, Space, Corrosion — Not Accuracy

    There are a variety of reasons for wanting accurate flow metering — e.g., billing purposes, precise proportioning of chemical injections, and other process flow decisions. That is why highly accurate mag meters are so popular in many applications. Now, new lightweight, corrosion-resistant mag meters provide the same advantages as plastic piping for harsh environments and flows that cover all the bases…and acids.

  8. Making Sense Of Water Distribution Data: Don’t Fear The Detail

    For many water-distribution workers and managers up to their elbows in muddy trenches and SCADA data, the drumbeat for ‘Big Data’ probably fades to background noise when dealing with immediate leaks and losses on the front lines. Don’t throw the baby out with the bathwater, however. Many answers we truly want are probably accessible through current water distribution data. We just need an easier way to wring them out.

  9. Rental Blowers Provide Timely Solutions For Temporary Aeration Concerns

    With a continuous flow of air required to maintain dissolved oxygen (DO) levels, the last thing a wastewater treatment plant (WWTP) operator wants is to come up short of the volume needed to sustain good microbial growth. With today’s ready availability of high-efficiency rental blowers, losing blowers to unplanned downtime or being unable to test new aeration systems before commissioning are no longer the threats they once were.

  10. Using Special Repair Fittings To Tame Tough Pipeline Problems

    For most water utilities, maintaining existing infrastructure — whether planned or in response to emergencies — is a large part of physical plant costs. Being prepared to respond is half the battle. Here are several guidelines and options to consider for maintaining the most cost-efficient solutions to everyday pipeline problems. As with most good plans, they start with proper organization.
