Designing an underground stormwater storage system is a unique step in the overall construction process for each site. The size of the inlets and the conveyance pipes are determined by flow rate, elevation, and slope. This information is entered and calculated by stormwater management software to determine the drainage calculation. But many of the measures build upon one another or vary based on different criteria, so it can be a pretty complex process. That’s why we’re going to take a look at the top 10 factors that go into designing and installing one of these systems.
Varkom D.D. (Varkom) brings water and wastewater utility services to 175,000 people across seven townships and 20 municipalities in Croatia. The organization wanted a feasibility study completed to help better manage its assets. Read the full case study to learn how the team estimated that 70 percent of time was saved directly in model preparation and an additional 70 percent of time was saved in model management and preliminary design.
Population health is a primary concern of water utilities, whether water demands are typical (daily demands) or an out-of-the ordinary event occurs and threatens the continuous, safe supply of potable water. Water utilities must be prepared to respond to emergencies before they occur, and this is where hydraulic modeling can be particularly useful.
Water and wastewater treatment plant design is a large scale, complex engineering effort that requires a multi-discipline design team, often spread across many offices, and involving collaboration among different consulting firms, contractors, and owners.
The industrial world is awash with data and new information from sensors, applications, equipment, and people.
A wide range of issues can disrupt the normal functioning of an urban water system, such as storms and other natural disasters, pollution, physical damage, cyber incidents, aging and insufficient infrastructure, and rapid urban growth.
Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).
In this white paper, learn how to decrease alarms due to redundant level devices not matching, especially in applications with high pressure and/or high temperature. The importance of Gas Phase Compensation (GPC) and how it affects level readings of guided wave radar (GWR) devices is critical. The presence of polar gas also can have an effect on the accuracy of any GWR that does not have GPC when installed in applications where high temperature or pressure is present. This paper will discuss these issues and address how to overcome them.
KUB's water system has experienced 30 percent to 35 percent non-revenue water over the past 10 years; hard-to-find underground leaks are the big culprit. Reducing leaks improves customer service, increases operational efficiency, reduces expenses for chemicals and power, and has other benefits.
Located just south of Montgomery, Alabama, the City of Troy is a unique mix of southern small-town charm and big-city amenities. Read the full case study to learn how the City leveraged Sensus’ Advanced Metering Infrastructure (AMI) solution to gather more data and monitor for issues likes leaks or pipe breaks
A stormwater management system designed for a new convenience store in Sarasota, FL, required a sophisticated and elaborate approach. When it was completed earlier this year, the complex system resulted in huge money and time savings for the property owner, which will enable the store to open this fall.
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.
There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.
Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

Sampling and laboratory testing are major responsibilities for water professionals. Test results are used for process control, and ultimately to determine that water is safe for drinking, reuse, or discharge to the environment. Regulatory agencies rely on reported results for proof of permit compliance. So, obtaining representative, properly collected and preserved samples is the first critical step to ensure accurate test results.
