In response to growing pressures on available water resources, potable reuse represents a practical source of drinking-water in many circumstances. This document describes how to apply appropriate management systems to produce safe drinking-water from municipal wastewater. Information is provided on specific aspects of potable reuse, including the quality and protection of source wastewaters, types of control measures, monitoring considerations and public acceptance. Application of potable reuse is also illustrated through a number of case studies.
Summary of UN-Water Global Analysis and Assessment of Sanitation and Drinking-Water (GLAAS) 2017-2020 Strategy
As countries pursue their WASH-related objectives, including in relation to the Sustainable Development Goals (SDGs), understanding country ambitions, policy-direction and financing becomes increasingly more complex and important. Following consultations at various international fora, the UN-Water GLAAS strategy for 2017-20 responds to the new demands of the SDGs and sets a course for GLAAS actions in the coming years.
13 July 2017 – Some 3 in 10 people worldwide, or 2.1 billion, lack access to safe, readily available water at home, and 6 in 10, or 4.5 billion, lack safely managed sanitation, according to a new report by WHO and UNICEF. The Joint Monitoring Programme report, Progress on Drinking Water, Sanitation and Hygiene: 2017 Update and Sustainable Development Goal Baselines, presents the first global assessment of “safely managed” drinking water and sanitation services. The overriding conclusion is that too many people still lack access, particularly in rural areas.
This document provides an overview of available tools and practical recommendations to support the assessment and management of risks to human health associated with chemical mixtures in drinking-water and its sources. The guidance builds upon the World Health Organization’s International Programme on Chemical Safety framework on combined exposures to multiple chemicals. The framework supports priority setting for assessing and managing chemical mixtures and its use is illustrated through a number of case studies relevant to the source water and drinking-water context.
13 June 2017 | GENEVA — Countries are not increasing spending fast enough to meet the water and sanitation targets under the Sustainable Development Goals (SDGs), says a new report published by the WHO on behalf of UN-Water.
The report stresses that countries will not meet global aspirations of universal access to safe drinking-water and sanitation unless steps are taken to use financial resources more efficiently and increase efforts to identify new sources of funding.
ADB/WHO handbook on Water safety planning for urban water utilities
This handbook provides practical guidance on integrating the water safety plan (WSP) approach into ADB's urban water projects to facilitate compliance with global good practices. Following the WHO’s Water safety plan manual (2009), adapted to ADB’s operations, this handbook offers step-by-step guidance on developing and implementing a WSP, serving as an example of how external support agencies may integrate WSPs into their urban water programmes.
Water safety planning is a comprehensive risk assessment and risk management approach that is widely recognized as the most reliable and effective way to manage drinking-water supplies to safeguard public health.
Based on information gathered from 118 countries representing every region of the globe, this report provides a picture of WSP uptake worldwide. It presents information on WSP implementation and the integration of WSPs into the policy environment. It also explores WSP benefits, challenges and future priorities.
A research agenda for WASH and antimicrobial resistance (AMR)
The role of WASH is critical in combatting AMR. Achieving universal access to WASH in communities and health facilities will help drive down avoidable antibiotic use. But not enough is known about the extent to which wastewaters (carrying antibiotic residues, resistant bacteria and their genes) are a driver of resistance and what can be done. WHO convened microbiology experts to develop a research agenda for WASH and AMR.
Water, sanitation and hygiene are essential for preventing and managing diseases including neglected tropical diseases which affect over 1 billion people among the poorest communities. Closer coordination of WASH and NTD programmes is needed to ensure WASH services are reaching the most vulnerable populations. Many WASH and NTD actors have started to work together on the planning and implementation of their projects and have documented their experiences and lessons learnt. This paper compiles examples from eighteen countries to summarize emerging successes and challenges.
WHO works on aspects of water, sanitation and hygiene (WASH) where the health burden is high and where evidence-based interventions could make a major difference.
