本文件包含拟将处理后的废水（TWW）用于灌溉的项目开发和执行指南，并考虑了气候和土壤参数。 本文件旨在为使用TWW进行非限制性和限制性灌溉的项目的所有要素提供指导，包括用于以下用途的设计、材料、施工和性能: -灌溉农作物； -灌溉公共和私人花园及景观区域，包括公园、运动场、高尔夫球场、墓地等。 这些指南旨在为灌溉用水的TWW用户提供帮助。该指南涉及广泛和常见的水质范围，而非特殊或独特的水质范围，旨在供专业人士使用，如灌溉公司（设计师和运营商）、农业推广官员或顾问、供水公司（设计师和运营商）、地方当局和水务设施。 用户使用这些指南可能需要额外的规范。 本文件的任何部分均不用于认证目的。 这些指南建议了TWW质量的参数。这些参数包括: -农艺参数:养分（氮、磷和钾）、盐度因子（总盐含量、氯化物、硼和钠浓度）和重金属浓度； -病原体的存在。 这些参数中的每一个都可能对作物、土壤和公共健康产生影响。该指南讨论了在废水生产过程中防止污染物添加的可能性，以及在处理过程中去除污染物的能力。 新出现的污染物（如药品和个人护理产品残留物）不在本文件的范围内，因为迄今为止，没有证据表明使用TWW灌溉或食用使用TWW灌溉的作物会对人类健康或环境产生不利影响。 该项目的设计应符合TWW的卫生质量，以避免水中病原体传播疾病。 鼓励使用这些指南，以确保参与处理废水使用的任何组织内部的一致性。 这些指南为使用经处理废水的灌溉系统的健康、水文、环境和农艺设计、操作、监测和维护提供了基础。

This document contains guidelines for the development and the execution of projects intending to use treated wastewater (TWW) for irrigation and considers the parameters of climate and soil. The purpose of this document is to provide guidance on all elements of a project using TWW for unrestricted and restricted irrigation, including design, materials, construction, and performance, when used for the following: — irrigation of agricultural crops; — irrigation of public and private gardens and landscape areas, including parks, sport fields, golf courses, cemeteries, etc. These guidelines are intended to provide assistance for the benefit of users of TWW for irrigation. The guidelines relate to the widespread and common ranges of water quality rather than exceptional or unique ones and are intended for the use of professionals, such as irrigation companies (designers and operators), agricultural extension officers or advisors, water companies (designers and operators), local authorities and water utilities. The use of these guidelines by users might require additional specifications. None of the parts of this document are intended to be used for certification purposes. These guidelines suggest the parameters of TWW quality. These parameters include the following: — agronomic parameters: nutrients (nitrogen, phosphorus and potassium), salinity factors (total salt content, chloride, boron, and sodium concentration) and heavy metals' concentration; — pathogen presence. Each of these parameters can have possible impacts on the crops, soil, and public health. The guidelines discuss the possibility of preventing the contaminants' addition during wastewater production and the ability to remove them during the course of treatment. Contaminants of emerging concern (such as pharmaceuticals and personal care product residuals) are outside the scope of this document since up to day, there is no evidence of adverse effects on human health or environment via irrigation with TWW or via the consumption of crops irrigated with TWW. The project should be designed in accordance with the sanitary quality of the TWW in order to avoid disease transmission by the pathogens in the water. The use of these guidelines is encouraged to ensure consistency within any organization engaged in the use of treated wastewater. These guidelines provide the basis for a healthy, hydrological, environmental and agronomic conscious design, operation, monitoring, and maintenance of an irrigation system using treated wastewater.
