In the Operating Range section, change the Use High Alarm? value to True.Double-click a tank element to open the associated Properties editor.You can specify upper and lower tank levels at which user notification messages will be generated during calculation. 014 of the total active volume (0.2, 0.014), and so on. At 0.2 of the total depth the tank stores 0. For example, at 0.1 of the total depth (depth ratio = 0.1) the tank stores 0.028 of the total active volume (volume ratio = 0.028).

In the Cross-Section Curve dialog that appears, enter a series of points describing the storage characteristics of the tank.

Click the ellipsis button (.) in the Cross-Section Curve field.

In the Properties window, click the Section menu and select the Variable Area section type.

To Define the Cross Section of a Variable Area Tank A depth-to-volume ratio table is used to define the cross sectional geometry of the tank.

In a variable area tank, the cross-sectional geometry varies between the minimum and maximum operating elevations. If the user selects Variable Area, it is necessary to provide a depth to volume table. If the tank has a constant cross section that is not circular, the user can select Non-circular and specify the cross sectional area. If a tank is made inactive, any connective pipes should also be made inactive as otherwise this will give an error.ĭefining the Cross Section of a Variable Area Tankīy default, tanks are treated as having a circular shape with a constant cross section described by its diameter. A tank can be made inactive (not used in calculations) by changing the Is active? property to False.

In the Properties window, click the menu in the Zone field and select the zone you want.īy default a tank is active in a model.

To Apply a Previously Created Zone to a Tank For more information on zones and their use, see Zones. A Zone can contain any number of elements and can include a combination of any or all element types. You can optionally group elements together by any desired criteria through the use of zones. The water level in a tank can be described based on either the hydraulic grade line elevation (Elevation) or the water level above the base elevation (Level). The user can choose either Elevation or Level as the Operating Range Type. The water surface elevation of a tank will change as water flows into or out of it during an extended period simulation.

A Storage Node is a special type of node where a free water surface exists, and the hydraulic head is the elevation of the water surface above some datum (usually sea level). The company supplies 2,000 million liters of water every day via a network of around 40,000 kilometers of water mains, 1,444 kilometers of aqueduct, and more than 100 water treatment works.Tanks are a type of Storage Node. United Utilities Water PLC owns and operates the water network in North West England. The winners will be announced during the IWA World Water Congress in Vienna, Austria, Sept. Having won in the European region, Bentley and United Utilities will now submit the project to IWA's global awards program, in which they will compete with winners from East Asia, the Pacific, and North America. The new Darwin Calibrator is included in the latest version of Bentley's WaterGEMS V8 XM and is available for Bentley's WaterCAD V8 XM.

Therefore, the software module maximizes water utilities' investments in hydraulic modeling technology." "It enables cost-effective water-loss reduction strategies and facilitates the creation of accurate hydraulic models by undertaking both leakage detection and hydraulic model calibration. "The enhancement to this innovative optimization tool solves a long-standing problem for the water industry," said Zheng Yi Wu, Ph.D., director of Applied Research in Engineering Optimization. The new version of the Darwin Calibrator modeling tool automates the new methodology. The focus of the Bentley and United Utilities award-winning project was the development of an innovative optimization methodology and modeling tool for detecting unreported leakages in water distribution systems – a problem that results in the annual loss of more 20 percent of potable water by water utilities worldwide. The IWA Project Innovation Awards recognize excellence and innovation in water engineering projects around the world.
