本文讨论了田纳西州杰克逊市杰克逊能源管理局（Jackson Energy Authority）为更新其水资源总体规划和 现有稳态水垫水力模型。水力模型更新与水系统 总体规划包括以下任务: 使用地理信息系统（GIS）和历史账单数据对水需求进行分类； 将现有的稳态WaterCAD模型改进为延长周期模拟 模型，并根据现场数据进行校准； 确定新水处理厂的最佳水力位置，并推荐 管道改进以满足未来工业增长； 为系统中面临挑战的区域提供运营解决方案，以节省资金 在运营成本方面，（取消了一座泵站，导致 每月仅在电力成本方面就可大幅节约）；和 为公用事业公司提供一个工具，以试验其水系统。例如，一个 可以使用水力模型开发单向冲洗程序。 经过校准的模型允许杰克逊能源管理局就以下问题做出明智的决定: 水系统的未来。此外，随着水系统的不断增长和变化， 可以更新模型以显示这些更改的影响。

This paper discusses an effort by Jackson Energy Authority in Jackson, Tennessee to update their water master plan and existing steady-state WaterCAD hydraulic model. The hydraulic model update and water system master plan included the following tasks: disaggregate water demands using geographic information system (GIS) and historical billing data; enhance the existing Steady-State WaterCAD model to an Extended Period Simulation model, and calibrate it to field data; determine the best hydraulic location for a new water treatment plant and recommend piping improvements to meet future industrial growth; provide operational solutions to challenged areas in the system, in order to save money on operation costs, (a pump station was eliminated, which resulted in significant savings per month in electrical costs alone); and, provide the utility with a tool to experiment with their water system. For example, a unidirectional flushing program could be developed using the hydraulic water model. The calibrated model allowed for Jackson Energy Authority to make informed decisions about the future of the water system. Furthermore, as the water system continues to grow and change, the model can be updated to show the effects of these changes.
