Water utilities constantly make decisions and take action in an attempt to meet high standards of service with minimal costs and disruption.
Large or established water utilities often have engineering staff devoted to hydraulic analysis, or they hire consultants with extensive expertise in modeling. Growing utilities typically do not have these luxuries. If they have an engineer on staff who can perform hydraulic analysis, that resource spends most of his time with several day-to-day responsibilities maintaining and repairing the network leaving very little time for operational planning and optimization. To do that one must build, update, and maintain a hydraulic model, which will consume a lot of time, when using inferior software with unintuitive GUI and lacking features and technical support.
Similarly, consultants working with these utilities must also be extremely cost-efficient. They often need to deliver projects within tight deadlines. The faster they learn using the tool, the faster they deliver the projects, and eventually, they can spend more time prospecting or working on newer projects.
This is where a small investment in highly efficient software like Bentley Systems’ OpenFlows WaterGEMS can deliver a very quick return on investment.

Save Time by Automating Hydraulic Modeling
Are you spending time on water distribution network modeling tasks that you wish could be automated or simplified?
With technology innovations, engineers can save hundreds of hours of time on repetitive modeling tasks and avoid inefficiencies.
Among the optimization features, WaterGEMS comprises a module called ‘Darwin Designer’. This module allows users to easily evaluate and identify the most optimal design and rehabilitation strategies based on three objectives: minimization of costs, maximization of benefits, or multi-objectives.
Additionally, you can enter restrictions, allowed pipe sizes, and associated unit costs to execute manual or automatic designs. The underlying technology uses a genetic algorithm for optimization.

Cut Down Your Energy Bill by Optimizing Pump Operation
Darwin Scheduler in OpenFlows WaterGEMS allows you to optimize pump operations. By using genetic algorithm optimization to control nominated pumps during an extended period simulation (EPS), it avoids a manual trial and error approach to finding the most efficient operating schedule. Solutions and costs calculated using Darwin Scheduler can be exported back to the selected scenario.
Previously, the only way to optimize pump operations in a model was to use trial and error, changing settings in the model manually and then computing the model. Darwin Scheduler allows for optimized solutions to be calculated with a genetic algorithm similar to that found in Darwin Calibrator.
This tool allows for a more efficient analysis of a model. The optimization only knows the best solution relative to other solutions already found during computation. The power of this is in that the study runs through a large number of possible solutions and can often find a very good solution to fit the model.
Darwin Scheduler is used in EPS models only. It is recommended that the model is well-calibrated so that you get the best results.

Hydraulic Analysis and Operations Made Easier
Here are some of the analysis features that are being used by growing utilities to save time and money:
• Scenario management – Quality software can efficiently evaluate several designs and compare the results or analyze the operation of an existing system under numerous extreme and typical conditions. In OpenFlows WaterGEMS, scenarios and alternatives are based on a parent/child relationship, making the analysis process efficient and flexible such that changes created in a dynamic design process do not have to be made and validated in several locations, but rather cascade through the hierarchy of the project.
• Easy model building –Jumpstart the model-building process and manage your model effectively so that you can focus on making the best engineering decisions. Leverage and import many well-known external data formats, which maximizes the return on investment for geospatial and engineering data and automates input data generation.
• Criticality analysis – OpenFlows WaterGEMS enables you to include all valves in a hydraulic model without increasing the number of pipe elements and degrading performance. Find the weak areas or links in water distribution systems and assess the adequacy of isolation valves. Evaluate the ability to isolate portions of the system, generate network segments and serve customers using different valve locations.
• Fire flow analysis – Access and identify inadequacy in fire protection and design improvements to meet fire-flow and protection requirements. Design improvements such as the sizing and location of pipes, pumps, and tanks in order to meet fire-flow and protection requirements. OpenFlows WaterGEMS includes automated fire flow analysis tools so that you do not have to manually create scenarios and iterations to evaluate every hydrant location.
• Assess water quality – Carry out water quality analysis easily using simulations to help solve water quality problems. You can create water quality simulations for chlorine decay, water age, source tracing and multispecies analysis (MSX), etc. OpenFlows WaterGEMS enables a comprehensive thematic display of results, both within and apart from GIS platforms, to get a clear understanding of how and where problem areas develop in your system.
• Flushing analysis – Optimize flushing programs with multiple conventional and unidirectional flushing events in a single run. Increase velocity in mains to flush out solids and stale water, with the primary indicator of the success of flushing being the maximum velocity achieved in any pipe during the flushing operation. OpenFlows WaterGEMS includes automated tools for flushing analysis, including the ability to print a sequenced report for use in the field.
