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.
The main lift station serving the waste water treatment plant in Morgan’s Point, Texas, continually experienced problems with its three standard non-clog pumps. The pumps frequently clogged when rainfall totals reached or exceeded 2 inches. Shop rags, pieces of 2 x 4 lumber, plastic bottles, gloves, and wet wipes all commonly clogged the pumps when the standard demand increased. Pump removal, unplugging, and recurring repairs were required, but the service company was not always available for immediate assistance, causing problems for residents serviced by this lift station.
Denver Water serves 1.4 million people in the city of Denver and the surrounding suburbs. It is the largest — and oldest — water utility in the state of Colorado and its service area covers more than 335 square miles.
Water industry professionals are experiencing a data deluge. There’s a lot of data out there, gathered from sensors monitoring everything from water quality to pipe bursts — but altogether, it’s too much data divided among too many silos to make sense of what it all means.
Maintenance and performance of pressurized water distribution systems require a complete grasp on the pressure ratings of every component within the system. Mueller gives valuable insight here for pressure rating standards needed for flanged valves.
The need for a solid cybersecurity strategy has been discussed and debated for almost a half a century now, and yet the basic worm-type attacks first documented back in 1972 are still with us today. Why? Because even the most basic measures to protect control systems from these types of attacks are still not systematically employed.
The City of Rushville, Indiana had to remedy a consent order filed in 2007 for its untreated combined sewer overflow (CSO) discharges that were polluting the Flatrock River, a violation of the Clean Water Act. The city originally planned to install a 1 MGD stormwater storage tank, but was approached by Aqua-Aerobic representatives with a pilot test proposal utilizing a new technology.
ABB provides an extensive selection of proven measurement and analytical products and solutions for power generation industry applications.
Digitalization of the municipal water treatment industry is fragmented today, with instrumentation, control, and automation technologies mixed with manual operational activities. Such infrastructures can be detrimental in cases of hydro-geological events, such as severe storms and earthquakes. The good news: When natural disasters strike, digitalization can help get municipal water treatment back online quickly and effectively.
The development of Industrial Control Systems (ICS) over the past two decades has changed the face of many industries. Operation Technology (OT) — largely industrial equipment — has become increasingly connected, and the integration of Information Technology (IT) components allows such devices to leverage software that drives data collection and analysis, resulting in enhanced performance and ultimately "smarter" machines.
A Chicago stormwater diversion tunnel designed to correct a chronic flooding problem that has plagued the city’s Albany Park neighborhood over the past decade has been recognized for its effectiveness and ingenuity.
Constant monitoring of critical motors while de-energized prevents failures on startup, reduces unscheduled downtime, saves on major rewinding repairs and increases personnel safety
Siemens offers to our customers the ability to both make process measurements and to remotely monitor the activity and health of that instrumentation without the need for SCADA systems or other expensive process control room products. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement as well as valve control, we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.
One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
Hach LDO® technology improves the efficiency of pharmaceutical plant’s wastewater treatment process, helping to protect the environment and the community.
Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.
Compliance and consistent high quality are two of the key goals within the beverage industry. Hach® provides support for these goals through comprehensive analyses of water and beer.
With concerns over stormwater management escalating, green stormwater infrastructure (GSI) offers a multi-benefit, cost-effective solution.
The journey toward intelligent water can be expedited with eight key steps — a guideline for gliding through the Digital Water Adoption Curve.
Ammonia removal is a key metric for assessing wastewater treatment facility performance. This is because ammonia contributes to aquatic life toxicity. Furthermore, nitrogen, along with phosphorus, is a driver of receiving water eutrophication. Eutrophication, which simply is an over-enrichment of nutrients, can be detrimental to environmental and public health. It can result in harmful algae blooms, dissolved oxygen depletion, fish kills, and other damaging impacts.
The goal of water plant operators is almost universal: to ensure they're providing quality water to customers while detecting leaks, running at optimal energy usage, and maintaining systems. The problem is traditional controls and SCADA systems have gotten so complex they can actually make the job more difficult. In this Water Talk interview, Malcolm Thompson, the chief financial officer of XIO, and Kevin Liscovitz, the chief operating officer of XIO, discuss newer technology making water plant controls as simple as possible for operators while providing better insight into asset management.
A watershed isn’t typically tied into a water system’s SCADA system, but students and others observing the health of the resources may have information that can be of great value to plant operators. This is just one example of when there is a need to enter remote manual data into a SCADA system. In this Water Talk interview, Dave Spencer, technical sales with VTScada from Trihedral Engineering, discusses advanced technology that promote improved oversight by allowing the transfer of data into, and out of, SCADA systems.
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.
