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

characterization to identify and understand how risks
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 —
the means by which risks can be controlled

what limits define acceptable performance and how
these are monitored
Establish procedures to verify that the risk
management plan is working effectively and will meet
the health-based targets
Develop supporting programmes (e.g. training, hygienic

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.
