How Hydraulic Modelers Use OpenFlows WaterGEMS to Improve Operational Efficiency for Water Networks

How often have you found that the measured and observed pressures of the water distribution system do not match the outputs from the theoretic hydraulic model? It is vital for decision making and meeting high standards of service with minimal costs and disruption to be able to calibrate your model more easily to obtain trustworthy outputs. However, this can be a hard task without the proper tools!

Do you frequently find yourself having to optimize the operation of a water distribution system with tight project delivery deadlines while simultaneously trying to keep your costs low?

Working with tools with inferior features, unintuitive and unfriendly Graphical User Interface GUI, and limited technical support makes it more difficult and time consuming to build, update, and maintain a hydraulic model.

So, why not opt for WaterGEMS to alleviate these issues? This is a solution that will make your job easier and faster! WaterGEMS has unmatched platform interoperability. Plus, it features an effective Scenario Management tool that helps simplify workflows, allowing you and your team to work more efficiently and smarter!

WaterGEMS will enable you to visualize and use the measured data to calibrate your model while making it easier and faster to find potential solutions for model calibration. Did you know that Virtuoso Subscriptions also help to keep costs down since they include one-on-one mentoring to accelerate the learning of your team?

Improving the Operational Efficiency of Water Networks is complex, but it shouldn´t be hard

You can´t manage what you can´t measure! If your hydraulic model cannot reflect the observed behavior of the physical network, you can’t plan and take actions to optimize its operations (reduce energy costs, manage pressure, and manage and reduce water losses).

One of the highest operational costs incurred from water networks are related to energy and revenue losses, which correlate to water losses and other inefficiencies. These costs outline why it is crucial to be able to see and measure the discharge and pressure values of the existing system, as well as what will result from planned improvements.

That´s why you need a solution that will enable you to seamlessly use and visualize real-time and/or historical data of the water distribution system. To improve your analysis and decision-making capabilities, WaterGEMS leverages that data to improve your hydraulic model.

Calibrating a water distribution hydraulic model can be more complex than you think! Finding solutions by changing values and properties by trial and error is tedious, time consuming requires a lot of thought and planning to get the right results.

OpenFlows WaterGEMS features a set of built-in tools to help you! For instance, the Darwin Calibrator employs a, genetic algorithm search method that is well-suited to optimize problems of a non-convex and multiple local-optimal solution nature. With assistance of this built-in tool your team will be able to speed up the calibration process. Work smarter, not harder!

The SCADAConnect Simulator, another tool featured in WaterGEMS, can automatically load data from an external data source, such as a SCADA system, into Darwin Calibrator to assist in calibrating a model. This allows modelers to be more assertive in evaluating and determining hydraulic properties (pressures, flows, tank levels, water quality and energy) caused by simulated events, such as a fire, pipe break or shutdown, override any controls or demands.

Support Decision-Making and Cut Down the Operational Costs

One of the biggest operational expenditures (Opex) of water distribution systems lies in energy consumption. Utilities can increase operational efficiency, which reduces operational costs by decreasing the pump energy consumption and the Non-Revenue Water (NRW) due to leaks.

Another set of tools featured in WaterGEMS, the energy manager analysis, provides a way to combine energy use with peak demands. You can even calculate energy consumption of the system with complex tariffs for electric power modeling. This can be done using the Energy Management analysis by modeling multiple scenarios and multiple pumps associated with a power meter to display energy and peak demand cost based on pump, pump station, power meter, scenario, or system wide.

With WaterGEMS you don´t have use antiquated trial and error methods to optimize pump operations. Instead, you can use Darwin Scheduler to determine optimized solutions. Darwin Scheduler uses a genetic algorithm to control pumps to save and reduce energy costs.

If you are concerned about finding pipes that are underperforming, WaterGEMS enables you to accurately identify which system elements are out of service during an outage. You can also identify which pipes should be rehabilitated before they cause system disruptions using WaterGEMS’ built-in Criticality Analysis and Pipe Renewal Planer.

If analysis leads you to retrofitting or a complete overhaul of the system in order to improve the operational efficiency, WaterGEMS will also save you time and effort (read this blog to know more how to make water network designing easier with WaterGEMS).

With the support of WaterGEMS, you will be able to effectively master complex systems while accurately considering the Total Expenditure (TOTEX), which can be defined as the summation of capital expenditure and operating expenses (CAPEX + OPEX). This is critical in order to guarantee effectiveness for sustainable financial growth and quick returns on the huge investments made.
