水再生设施（WRF）的优化运行是至关重要的间接饮用水回用（IPR）系统，特别是当再生水构成的安全产量的主要部分，如在位于北方弗吉尼亚州的Occoquan水库的情况下。本文介绍了如何水库模型用于预测未来水库条件的基础上，从气候预报系统和国家水模型获得的天气和径流预报。由此产生的模型预测为操作员提供了有价值的反馈，以便使用工厂操作和称为IViewOps（智能操作视图）的优化模型来正确地瞄准污水硝酸盐。集成模型通过新开发的集成建模软件URUNME运行，形成决策支持系统（DSS）。该系统捕获的动态变化的营养负荷的流，提取的水处理厂，WRF的流出物流量，以及工厂的操作，以管理营养水平的基础上的硝酸盐吸收能力的水库。DSS可以为多个利益相关者提供设计，规划，风险评估和供水链各个组成部分的潜在改进的整体视图，不仅在Occoquan中，而且在任何水库扩建型IPR系统中。
Optimal operation of water reclamation facilities (WRFs) is critical for an indirect potable reuse (IPR) system, especially when the reclaimed water constitutes a major portion of the safe yield, as in the case of the Occoquan Reservoir located in Northern Virginia. This paper presents how a reservoir model is used for predicting future reservoir conditions based on the weather and streamflow forecasts obtained from the Climate Forecast System and the National Water Model. The resulting model predictions provide valuable feedback to the operators for correctly targeting the effluent nitrates using plant operations and optimization model called IViewOps (Intelligent View of Operations). The integrated models are run through URUNME, a newly developed integrated modeling software, and form a decision support system (DSS). The system captures the dynamic transformations in the nutrient loadings in the streams, withdrawals by the water treatment plant, WRF effluent flows, and the plant operations to manage nutrient levels based on the nitrate assimilative capacity of the reservoir. The DSS can provide multiple stakeholders with a holistic view for design, planning, risk assessments, and potential improvements in various components of the water supply chain, not just in the Occoquan but also in any reservoir augmentation-type IPR system.
