为解决Elyria水处理厂的冰堵和水质问题，修建了一座取水口 这项研究是在2007年夏天进行的，重点是开发和评估新的摄入量 选择。替代发展所需的信息是通过公共数据获取的 搜索、海上调查和模型模拟。模型结果和水柱分析 表明新取水口（离岸3000英尺）的平均原水质量有所改善 与当前取水点（离岸1300英尺）相比。 水质监测表明 在风暴期间，新址的水质可能会波动。 根据湖泊条件和取水口要求，设计了两种替代取水口设计 调查:将现有进水管延伸至离岸3000英尺，并安装一个新的婴儿床； 安装一个新的、更大的进气管和婴儿床。经济标准和非经济标准是一致的 用于评估和比较这两个备选方案。替代评估的结果 结果表明，尽管扩建方案的施工成本较低，但新的进水管 替代方案将显著提高系统容量、可靠性和灵活性。设计 本研究还讨论了标准，以便对摄入量进行实际评估 选择。包括6个参考文献、表格、图表。

To resolve ice blockage and water quality issues for Elyria Water Treatment Plant, a water intake study was conducted in the summer of 2007, focusing on developing and evaluating new intake alternatives. Information required for alternative development was acquired through public data search, offshore investigation, and model simulation. Model results and water column analysis indicated improved average raw water quality at the new intake site (3000 feet offshore) compared with the current intake site (1300 feet offshore). Water quality monitoring implied that water quality in the new site may be fluctuant during storm events. Based on lake conditions and intake requirements, two alternative intake designs were investigated: extending the existing intake pipe to 3000 feet offshore and installing a new crib; and, installing a new, larger intake pipe and crib. Economic and non-economic criteria were adopted to evaluate and compare these two alternatives. The results of the alternative evaluation showed that although the extension alternative has lower construction cost, the new intake pipe alternative will significantly improve the system capacity, reliability, and flexibility. Design criteria were also discussed in this study in order to provide a practical evaluation of the intake alternatives. Includes 6 references, tables, figures.
