Every city facing infrastructure or operational challenges or concerns about maintaining quality of life in the face of population growth or a changing environment has benefits to gain from a unified smart-city approach. Here are some concepts for promoting understanding and acceptance among utility and government decision-makers, plus several examples of benefits already being garnered by smart cities large and small.
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.
City Utilities of Springfield, MO, a multiservice utility delivering electricity, natural gas, and water services to more than 106,000 customers, needed a way to provide timely data about consumption and efficiency to customers across its three different service offerings. While existing technology offered visibility into gas and electricity consumption for the utility and its customers, the options for managing water usage were limited.
Corrosion control has always been a priority for distributing safe drinking water throughout the world’s networks of pipeline. This has become all the more critical following the outrageous lead poisoning revelations in Flint, MI — an incident caused directly by corrosion of the city’s lead-based infrastructure.
Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.
In 2008, the public utility manager in Ogden City, Utah sent out a request for proposal on a system-wide changeout of its meters, absolute encoders, and radio frequency meter interface units (RF MIUs), with a goal of eliminating estimating and replacing all their meters with AMR technology to read year-round. Read the full case study to learn more.
With any technology, new capabilities are typically associated with new requirements and responsibilities. While the bottom line of customer billing based on advanced metering infrastructure (AMI) essentially remains the same as it was with manual meter reading, the technology introduces some new “technical issues” regarding data security. For example, while more frequent RF data collection enables added layers of data insight, it also creates a new channel for potential data exposure.
The Water Department in the City of Redmond, which serves approximately 28,000 residents, needed to streamline its process of collecting meter reads to save costs and improve data integrity.
United Water New Jersey (UWNJ), a subsidiary of United Water, one of the leading water and wastewater service providers in the United States, provides water services to more than 800,000 people throughout Bergen and Hudson counties and surrounding areas. By Mueller Water Products
While the majority of household consumers believe that they deserve the full attention of a water system, from a revenue perspective this does not bear out. Though the average home faucet is undoubtedly valued by its drinking water provider, the reality is that the vast majority of drinking water revenue comes from heavy-use commercial and industrial operations.
The county seat of Shelby County, Sidney, Ohio straddles the Miami River Valley 40 miles north of Dayton and 85 miles west of Columbus. Named after Sir Philip Sidney, poet and member of British Parliament, the City is home to a population of a little over 21,000.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
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.
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.
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.
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 simplicity of the compact, battery-powered Telog HPR-31 enables you to put it to work within minutes of unpacking. Once installed, the Telog HPR-31 measures water pressure at user programmable rates up to four samples per second with its internal pressure transducer. You can determine how often such data is summarized for reporting. The recorder computes any combination of minimum, average and maximum pressure measurement at each interval according to your selection of statistics and recording intervals. Recorded data may be gathered via an RS-232 connector using a handheld device or a laptop.
There are many different jobs related to tanks, but there are three types of jobs that can be considered together because they are more closely connected. These are the design, installation oversight, and "as-builts" design for both underground storage tanks (USTs) and above-ground storage tanks (ASTs). All three of these jobs, in the respective order above, should in reality be part of the same tank installation job.
Denver Water and engineering partners resolve major water quality challenge in crucial South Platte River exchange reservoirs.
The lessons of Flint should be well heeded, and lead mitigation continued, but the big-picture story of lead exposures in the U.S. is a tale of tremendous progress.
Most utilities understand they have a nonrevenue water problem, but few know how to deal with it correctly. Start by learning more about how the issue affects your utility and what options are available.
University of Miami professors who study water treatment and civil engineering say that water contamination issues point to human error.
