Disinfection of drinking-water supplies has been one of the most significant public health advancements of the last century with respect to reducing waterborne disease.
Although chlorine has been used as the disinfectant of choice for public drinking-water supplies for the past century, a numbe...r of emerging or alternative compounds are used or are being considered for the disinfection of drinking-water.
This series reviews the state of the knowledge on the application, efficacy and toxicity of bromine, iodine and silver as drinking-water disinfectants.

This manual is part of a series of guides devised by the Oxfam Public Health Engineering Team to help provide a reliable water supply for populations affected by conflict or natural disaster. The equipment is designed to be used with any or all of the following Oxfam water equipment: Water Pumping e...quipment, Water Storage equipment, Water Filtration equipment, Water Distribution equipment, Hand-dug Well equipment, and Water Testing Kit. All are designed using available, easily transported equipment which is simple, rapidly assembled, and fully self-contained, to provide an adequate, safe water supply at moderate cost. The principles used in these packages may often be useful in long-term development projects.

This manual is part of a series of guides devised by the Oxfam Public Health Engineering Team to help provide a reliable water supply for populations affected by conflict or natural disaster. Storage tanks are required for collection of water from springs or water produced from continuous flow water... treatment systems, e.g. from upflow clarifiers or slow sand filters. There should be sufficient storage volume to store all water produced overnight, as this is unlikely to be collected by users during the night. Storage tanks also have secondary functions such as ensuring a constant water supply to treatment processes, providing a level of treatment by settlement of larger suspended solids and maintaining pressure in distribution systems

A review of proactive risk assessment and risk management practices to ensure the safety of drinking-water
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 implementati...on and the integration of WSPs into the policy environment. It also explores WSP benefits, challenges and future priorities.

A field manual for Red Cross/Red Crescent personnel and volunteers
This primer aims to guide health professionals on engaging with WASH-related issues. It gives an overview of WASH interventions and the status of WASH services globally and outlines key linkages with health. It provides examples of key actions that health actors can take to ensure WASH efforts effec...tively protect public health and highlights World Health Organization (WHO) activities to support those actions.

The workshop is structured around 13 learning modules. The first module (Introduction) gives an overview of WSPs. The last module (Module 12) introduces participants to the quality assurance tool for WSPs (WHO & IWA, 2012). Modules 1–11 relate explicitly to the WSP manual produced by IWA and WHO (...Bartram et al., 2009), from which the workshop is designed.

World Vision’s Gender Equality and Social Inclusion (GESI) approach actively strives to examine, question, and change harmful social norms and power imbalances as a means of reaching gender equality and social inclusion objectives in a programme area.
This reference guide is designed to help WASH... practitioners implement GESI-transformative WASH programmes by supporting change across all five GESI domains – access, decision-making, participation, systems, and well-being. It provides information on how to design, implement, monitor and evaluate a WASH project or programme to address GESI.

These guidelines deal specifically with water, sanitation and hygiene, and are designed to be used in schools in low-cost settings in low- and medium-resource countries to:
• assess prevailing situations and plan for required improvements;
• develop and reach essential safety standards as a f...irst goal; and
• support the development and application of national policies.

This report presents, for the first time, a global assessment of the extent to which health care facilities provide essential water, sanitation and hygiene (WASH) services. Drawing on data from 54 low- and middle-income countries, the report concludes that 38% lack access to even rudimentary levels ...of water, 19% lack sanitation and 35% do not have water and soap for handwashing. When a higher level of service is factored in, the situation deteriorates significantly. A number of areas require urgent action and WHO will work with UNICEF, Governments and other partners to develop a global plan to address the most pressing needs and ensure that all health care facilities have WASH services.

February 2020Earth's Future 8(2):e2019EF001377.The water planetary boundary attempts to provide a global limit to anthropogenic water cycle modifications, but it has been challenging to translate and apply it to the regional and local scales at which water problems and management typically occur. We... develop a cross‐scale approach by which the water planetary boundary could guide sustainable water management and governance at subglobal contexts defined by physical features (e.g., watershed or aquifer), political borders (e.g., city, nation, or group of nations), or commercial entities (e.g., corporation, trade group, or financial institution).

This guide is intended for people involved in the management and operation of small- to mediumsized organized water supply systems. The content has been developed with particular consideration for operational-level personnel with responsibility for chlorination (for example, water treatment plant op...erators and technicians). The material presented within this guide may also be relevant for engineers and representatives from public health, local government, non-governmental organizations, as well as any other individuals supporting water safety planning activities for the supply of safe drinking-water.
Part 1. Chlorination principles: Describes key chlorination concepts, providing a knowledge foundation for the implementation of effective chlorination practices.
Part 2. Chlorination practices: Describes the practical application of the concepts presented in Part 1, including calculations and procedures for safe and effective chlorination of drinking-water supplies.

This technical brief presents the current options for safe storage and point of use water treatment. It is intended to help field staff working in a variety of locations to decide upon the most appropriate course of action for providing safe water for the communities in which they work. The effectiv...eness of household water treatment options now and in the future rely to a huge extent on user compliance; it is critical that users are involved in the decision making process, and are aware of the purpose, how to use, maintain and manage their household water options. The brief therefore details relevant hygiene promotion steps for the different treatment options.
