GeoAdvice can help you with your UDF modeling needs. Uni-directional flushing (UDF) consists of isolating particular pipe sections or loops by closing the appropriate valves and opening hydrants in an organized sequential manner. By using a UDF modeling approach, GeoAdvice will be able to generate significant system improvements and cost savings.
Modeling Best Practices, Standards, Conventions, and Flags for Models
GeoAdvice will establish modeling rules to follow when building, analyzing, or updating your model. A list of modeling standards, conventions, and checks will be developed to provide a framework for the correct execution of modeling tasks and to ensure conformity, accuracy, and confidence in your model—irrespective of the modeler. GeoAdvice will develop customized modeling standards for all modeling components (physical and non-physical elements); complete with clearly defined rules and advice. GeoAdvice will compose a comprehensive list of data parameter flags and validation tools.
Adopting modeling standards will:
- Reduce the effort needed for modeling
- Enhance the accuracy of your model
- Promote consistency between models
- Enhance clarity in cases of potential modeling ambiguity or inaccuracy
- Enhance the aesthetic and professional appearance of your model
- Provide meaningful modeling data to be used in projects
- Provide better understanding of your model in case of reuse after a long duration of time
Before starting your development application, GeoAdvice will meet with you to ensure that we understand the “context” of your development. Among the items we want to discuss would be the history of the development (is this new, or has it been in the works for some time), known issues in the utility systems within the vicinity of the proposed development, the Municipality’s history/relationship with the developer, etc.
GeoAdvice will assess the hydraulic capacity of the existing systems to service your proposed development, and determine the impact of the proposed development on the Municipality’s utility systems.
Finally, GeoAdvice will assess potential solutions to address any capacity deficiencies caused by the proposed development or any additional upgrades required to provide adequate service to the development.
Pressure Management in Water Distribution
A calibrated model can be used to assess the operating pressures and the design pressure management schemes. In turn, this can:
Reduce system leakage
Prolong the life of your assets
Reduce burst incidents
Reduce pressure-related demand
By staying focused on your needs, GeoAdvice creates practical solutions and strategies so you can effectively use geographical information systems (GIS) with your models. GeoAdvice’s GIS solutions follow industry standards, provide a solid platform for future growth, and are open for integration.
As a consulting firm working on a broad array of projects, GeoAdvice has met many of the challenges which utilities can face as they integrate GIS programs into their models. Happy Integration!
Avoid trial and error to calibrate your model; GeoAdvice uses GA optimization to match model predictions with field measures.
Genetic algorithm (GA) optimization is a search technique that is best suited to solving large optimization problems which cannot be solved using more conventional research methods.
Genetic algorithm optimization has been successfully applied to reduce pumping costs. Pumping costs are one of the most significant investments made annually by water utilities, yet very few take the time to assess their system operations—thus failing to identify potential savings that could save them many thousands or hundreds of thousands of dollars.
The GA model can be used to optimize pump operation (for example, maximizing pumping during periods of cheaper electricity) and allow the modeler to assess the efficiency of the existing pumps as well as any need for replacements and the potential reduction in running costs.
