  • How Seismic Use Group Classification affects your Water Storage Tank

    When purchasing a bolted steel tank or a welded steel water storage tank, one of the key criteria determining the design parameters of the tank is the Seismic Use Group (SUG) classification. The term Seismic Use Group is essentially the same as the terms Occupancy Category and Risk Category used by the International Building Code (IBC) and the ...

  • Rainfall changes blamed for India’s groundwater depletion

    Changes in rainfall may be responsible for reducing groundwater storage in India more than withdrawals for agricultural irrigation, according to a recently published analysis. Overextraction has long been thought to be responsible for declines in groundwater, but the researchers found less rainfall to be a more important factor. They believe it’s the result of higher temperatures in the ...

  • Baseflow recession characterization and groundwater storage trends in northern Taiwan

    Groundwater is a critical component of the terrestrial water budget and acts as a relatively stable water source in Taiwan. In the present study, river basins' characterization and groundwater storage trends in northern Taiwan are analyzed using the Brutsaert method. As groundwater storage sustains baseflows in a water system during dry periods, it can be assessed directly from the streamflow ...

  • Inference of basin flood potential using nonlinear hysteresis effect of basin water storage: case study of the Koshi basin

    Current flood forecasting tools for river basins subject to extreme seasonal monsoon rainfall are of limited value because they do not consider nonlinearity between basin hydrological properties. The goal of this study is to develop models that account for nonlinearity relationships in flood forecasting, which can aid future flood warning and evacuation system models. Water storage estimates ...

  • Flow Rate Determination For Active Mixers In Water Storage Tanks

    When water flows through a defined area such as a pipe or the inlet / outlet port of a pump, the flow rate is simply the measurement of how much water passes through an "imaginary plane" in a certain amount of time. This method of defining flow rate is so basic that it is adopted by engineers and equipment manufacturers everywhere for virtually all products in the water industry including pumps, ...

  • Water Storage Tank Mixing- Active or Passive?

    First off, providing a complete mix for your potable water storage tanks should be a 100% best practice for every tank all the time. Because mixing ensures that no water get “old” and that chlorine from new water entering the tank is spread throughout the whole tank. So mixing not only solves water quality and treatment problems, it helps prevent problems. Since proactive mixing for ...

  • Potable tank THM reduction - Case study

    Overview: This tank is a concrete cylindrical potable water storage tank that serves the area's distribution system. The tank is 130 ft. diameter x 22 ft. high, with a capacity of 2.0 million gallons (MG). The maximum inflow rate is 6.3 million gallons per day (MGD). The tank receives water from a reservoir, which is treated at a water treatment plant. This plant is a direct filtration surface ...

  • Analysis of the spatio-temporal variability of terrestrial water storage in the Great Artesian Basin, Australia

    The Great Artesian Basin (GAB) in Australia, the largest artesian basin in the world, is rich in groundwater resources. This study analyzed the spatio-temporal characteristics of terrestrial water storage (TWS) in the GAB for 2003–2014 using satellite (Gravity Recovery and Climate Experiment, GRACE) data, hydrological models’ outputs, and in situ data. A slight increase in TWS was observed ...
