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

[09:24 . 45]派克国家研究委员会（NRC）的水科学和技术委员会将对城市污水的水回收和再利用潜力进行全面研究，以扩大和提高国家可用的水供应替代方案。这项广泛的研究将考虑广泛的用途，包括饮用水、非饮用水城市用途、灌溉、工业过程用水、地下水补给和环境用水。该研究将考虑增加水再利用的技术、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指导。NRC的研究将由大约14名志愿专家组成的委员会进行，并得到NRC工作人员的支持。该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。水资源保护、水交易、海水淡化以及饮用水和非饮用水的再利用都是面临供水短缺的社区密切关注的问题。更好地了解各种形式的水再利用的成本、环境和人类健康风险以及效益，对供水规划至关重要。在评价人类健康风险，特别是间接饮用水再利用的风险以及相对于其他替代办法的能源需求方面，最近的技术进展和过去十年的研究值得进行彻底审查。这项研究还将确定技术障碍和研究需求。该委员会的工作结果将出版一份报告，该报告将考虑增加采用水再利用所面临的技术、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际指导。还将根据最后报告制作一份简短（约8页）彩色小册子，以广泛传播报告的调查结果。对水的再利用办法、现有的技术及其性能、有关的费用以及公众对这些办法的接受程度进行广泛的评估，将为正在考虑今后的供水办法的公用事业公司提供有用的资料。委员会大多数会议的部分会议将在公开会议上举行，与会者包括公用事业公司、非政府组织、有关的联邦、州和地方机构、其他专家和其他有关方面，以便让来自水管理和政策界的广泛个人团体参与进来。

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.
