After analyzing annual water loss audits for the city of Dallas, GA, the team discovered significant issues around non-revenue water. In 2014, real and apparent water loss accounted for 31.3 million gallons — nearly 20 percent of the city’s total water supplied for the year — which meant lost revenue for the city.
Election season is in full swing and while it may not be the “hottest” topic being debated amongst presidential candidates, the topic of water isn’t being ignored as we approach November. Several candidates have addressed the challenges plaguing water and wastewater systems nationwide.
Every morning when you pour a cup of coffee or tear open a package of frozen waffles, the science of Dow Chemical is there to help make your breakfast convenient and fresh. Dow makes high-performance materials that go into food packaging, personal care products, medications, and clothing — to name a few.
Easton Suburban Water Authority (ESWA) is in the business of providing water to its customers, not managing technology. One summer, Technology Manager Tim Ryan had enough with focusing valuable time and resources on the utility’s Advanced Metering Infrastructure (AMI) IT network and servers.
Buchanan County had a project which required repairs to a pumping station that boosts the pressure high enough to get water to a tank at the top of a mountain. The line pressure needed to accomplish this is 250 psi. After considering options, Buchanan County selected the Hydra-Stop Insta-Valve 250 Patriot. Read the full project profile to learn more.
When the jobsite is in an urban or metropolitan area measures must be taken to try to minimize the perception of nuisance or harm. Utility contractors face this situation often when they are called to make repairs.
This white paper describes how utilities can apply TCO evaluation, which takes into account on-going operations costs, replacement and lifecycle costs and personnel, as well as initial capital investment, to get a more complete picture of what systems will actually cost over time. These TCO calculations prove that point-to-multipoint fixed-network solutions can provide the best TCO of any competitive system, including manual, drive-by or mesh fixed-network solutions.
Millions of miles of plastic and metal pipe lie underground, carrying the nation’s water to our homes and businesses. Most of this pipe dates back to the 1940s and earlier. Given the age, it is not surprising that municipalities are often faced with repairs related to water infrastructure. By Brett Hanes
Sun Chemical Advanced Materials’ parent company, the DIC Corporation, is pleased to announce that it has expanded production capacity of its large size degasification module (LDM), SEPAREL® EF-120, by building a new plant.
The primary goal of public or privately owned utilities has always been to cost-effectively and efficiently deliver electricity, gas, and water to consumers. However, utilities today cope with added pressures. They are being asked to do more with less, contending with smaller workforces and less capital expenditures while at the same time trying to prevent assets from becoming obsolete. By Aclara
Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.
The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
One of the most popular uses for the Telog Hydrant Pressure Recorders (HPRs) is to monitor and analyze customer pressure complaints. The HPR is ideally suited for this application because it is rugged, highly portable, and can give a complete, time stamped picture of the pressure differential between the customer’s water pressure and the water pressure being delivered by the utility.
A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.
For many utilities, failing pipelines and non-revenue water are atop the list of concerns. However, these issues can be greatly mitigated by leveraging readily available data in an intelligent way — through smart water management.
Thousands of water professionals recently met for the industry’s annual flagship conference — an important event at an important time as we give attention to our nation’s infrastructure. While roads and bridges are visible reminders of the importance of infrastructure, equally important components are out of sight, but they need to always be in our mind. These critical components are underground pipelines that provide water and wastewater service.
Every water distribution utility has a strategy for infrastructure asset management and repair — from simply reacting to breaks, to scheduling main replacements based on system-specific history, to prioritizing infrastructure repairs based on mathematical calculations of risks and consequences.
While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
Computational fluid dynamics (CFD) modeling was applied to a circular water storage reservoir, proving invaluable for understanding hydraulic characteristics, developing a plan for mixing efficiency, and maintaining water quality.
