MONITORING AND SYSTEM
ASSESSMENT
102
Guidelines for the safe use of wastewater, excreta and greywater
Volume 4: Excreta and greywater use in agriculture
Assemble the team to prepare the risk management plan

can be managed in the system
Assess the existing or proposed system (including a
description of the system and a flow diagram)
Identify control measures —

procedures

Guidelines for the safe use of wastewater, excreta and greywater
The third edition of the WHO Guidelines for the safe use of wastewater,
excreta and greywater has been extensively updated to take account of
new scientific evidence and contemporary approaches to risk management.
The revised Guidelines reflect a strong focus on disease prevention and
public health principles.
This new edition responds to a growing demand from WHO Member
States for guidance on the safe use of wastewater, excreta and greywater
in agriculture and aquaculture. Its target audience includes environmental
and public health scientists, researchers, engineers, policy-makers and
those responsible for developing standards and regulations.
The Guidelines are presented in four separate volumes: Volume 1: Policy
and regulatory aspects; Volume 2:Wastewater use in agriculture; Volume 3:
Wastewater and excreta use in aquaculture; and Volume 4: Excreta and
greywater use in agriculture.
Volume 4 of the Guidelines focuses exclusively on the safe use of excreta
and greywater in agriculture. Recent trends in sanitation, including ecological
sanitation, are driven by rapid urbanization. The momentum created by the
Millennium Development Goals is resulting in dramatic changes in human
waste handling and processing. New opportunities enable the use of human
waste as a resource for pro-poor agricultural development, particularly in
periurban areas. Best practice to minimize associated health risks is at the
heart of this volume.

準則的安全使用廢水，污水和灰水
世衛組織準則的安全使用廢水的第三版，
污水和灰水已被廣泛更新，考慮到
新的科學證據和現代的風險管理方法。
修訂后的準則反映強烈的重點放在疾病的預防和
公眾健康的原則。
這個新版本做出反應，即世衛組織會員不斷增長的需求
國家有關安全使用的廢水，污水和灰水指導
在農業和水產養殖業。它的目標受眾包括環境
和公共衛生的科學家，研究人員，工程師，決策者和
那些負責制定標準和法規。
該指引載于四個不同的卷：卷1：政策
和監管方面的問題;第2卷：農業廢水利用;第3卷：
在水產養殖廢水和糞便使用;和第4卷：糞便和
在農業中水的使用。
指引第4卷只關注安全使用糞便
和灰水在農業中。最近的趨勢在衛生，包括生態
衛生，是通過快速的城市化驅動。由創造的勢頭
千年發展目標是造成人類巨大的變化
廢物處理和加工。新的機會能夠使用人類
垃圾作為一種資源用于有利于窮人的農業發展，特別是在
城郊地區。最大限度地減少相關的健康風險的最佳做法是在
心臟本卷。
