Chester’s advanced water system modeling capabilities are employed in support of engineering and geosciences projects to help clients evaluate water system capabilities, identify system weaknesses, and develop and test potential system improvements. Our water distribution system models provide full-extended period and continuous simulation capabilities, allowing us to analyze the performance of water systems under the dynamic conditions in which they actually occur. Chester’s comprehensive approach includes 5 essential steps:
1. Conceptualization of the environmental system and conditions being investigated. Problems may range from low water pressures in the potable system to the provision of water to an expanded service area.
2. Visualization of the system, which is then modeled to determine whether all system variables and inter-relationships have been properly accounted for. This step makes extensive use of Chester’s geographic information systems capabilities and graphic tools.
3. Model Selection to determine how accurately the physical components of the environmental system are being represented. The availability and quality of required input data is critical to the successful model selection.
4. Model Application, employing iterative model runs and parameter adjustments until reliable results are obtained.
5. Model Interpretation, facilitated by the Chester Team, is the necessary final step - ensuring that clients fully understand their modeling results and that the information will assist them in making decisions about the future of their water system.
The results and implications of a water model can help municipalities strategically manage their water systems, weighing the costs and benefits of potential projects and system modifications. Chester’s computerized hydraulic modeling can also be employed as we design facilities, address construction stage issues and provide system operational support.
