Assessment of Water Reuse as an Approach for Meeting Future Water Supply Needs

0924454帕克国家研究理事会（NRC）的水科学和技术委员会将进行一项综合研究，探讨水回收和城市废水再利用的潜力，以扩大和加强国家现有的供水替代方案。 这项广泛的研究将考虑广泛的用途，包括饮用水、非饮用城市用途、灌溉、工业工艺用水、地下水补给和环境用水。 该研究将考虑增加采用水再利用的技术，经济，体制和社会挑战，并为决策者评估其供水替代方案提供指导。 NRC的研究将由一个由大约14名志愿专家组成的委员会在NRC工作人员的支持下进行。 委员会将举行大约五次会议，听取简报，收集信息，审议关键问题，并撰写报告。随着水需求和环境需求的增长，扩大传统水源的选择正在减少。 面临水供应短缺的社区正在密切审查保护、水交易、脱盐以及饮用水和非饮用水的再利用。 更好地了解各种形式的水回用的成本、环境和人类健康风险以及好处对供水规划至关重要。 在评估人类健康风险，特别是间接饮用水再利用的风险以及相对于其他替代品的能源需求时，应彻底审查最近的技术进步和过去十年的研究。 这项研究还将查明技术障碍和研究需要。 该委员会的工作成果将是一份出版的报告，该报告将考虑增加采用水再利用的技术、经济、体制和社会挑战，并将为决策者评估其供水替代方案提供实用指导。 还将根据最后报告制作一份简短的（约8页）彩色小册子，以广泛传播报告的调查结果。 对水再利用备选办法、现有技术及其性能、相关费用及其为公众所接受的程度进行广泛的评估，将为正在考虑未来供水备选办法的公用事业提供有用的信息。 委员会的大多数会议的一部分将与公用事业公司、非政府组织、相关的联邦、州和地方机构以及其他专家和其他有关各方举行公开会议，以便让来自水管理和政策界的广泛的个人参与进来。

0924454Parker The Water Science and Technology Board of the National Research Council (NRC) will undertake a comprehensive study of the potential for water reclamation and reuse of municipal wastewater to expand and enhance the nation's available water supply alternatives. This broad study will consider a wide range of uses, including drinking water, non-potable urban uses, irrigation, industrial process water, groundwater recharge, and water for environmental purposes. The study will consider technical, economic, institutional, and social challenges to increased adoption of water reuse, and it will provide guidance to decision makers evaluating their water supply alternatives. The NRC study will be carried out by a committee of approximately 14 volunteer experts, with support from NRC staff. The committee will hold approximately five meetings to receive briefings, gather information, deliberate critical issues, and write its report. As water demands and environmental needs grow, options for expanding traditional sources of water are diminishing. Conservation, water trading, desalination, and potable and non-potable water reuse are all being closely examined by communities facing water supply shortages. An improved understanding of the costs, environmental and human health risks, and benefits of various forms of water reuse are essential to water supply planning. The recent advances in technology and the past decade of research deserve a thorough review in the context of evaluating the human health risks, particularly for indirect potable water reuse, and the energy requirements relative to other alternatives. The study will also identify technical barriers and research needs. The results of the committee's work will be a published report that will consider technical, economic, institutional, and social challenges to increased adoption of water reuse and will provide practical guidance to decision makers evaluating their water supply alternatives. A short (~8 page) color brochure will also be produced based on the final report for broad dissemination of the report's findings. A broad assessment of water reuse options, available technologies and their performance, associated costs, and their acceptance by the public would provide useful information for utilities that are considering future water supply alternatives. Parts of most meetings of the committee will be held in open session with utilities, non-governmental organizations, relevant federal, state, and local agencies, and other experts, and other interested parties in order to engage a broad group of individuals from the water management and policy community.
