The Guidelines for drinking-water quality: small water supplies have been developed to address the needs and opportunities associated with small supplies to facilitate progressive improvement towards safe and sustainable drinking-water services for all. These Guidelines are based on the principal re...commendation in the World Health Organization’s Guidelines for drinking-water quality, and they provide guidance on applying that recommendation to small water supplies in particular. These Guidelines aim to help governments and practitioners improve the safety of drinking-water delivered through small supplies.

A sanitary inspection is a simple, on-site evaluation (traditionally using a checklist) to help identify and support the management of priority risk factors that may lead to contamination of a drinking-water supply. Sanitary inspections are a well-established and widely-applied practice. They can su...pport water safety planning, and in some contexts, may be a simplified alternative to water safety plans.
This publication presents the World Health Organization’s (WHO’s) sanitary inspection packages. These packages update the sanitary inspection forms in WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. With more than 25 years of practical experience with the application of sanitary inspections, these packages have been developed from a comprehensive evidence review and established good practices.

Oxfam Water Supply Scheme for Emergencies. 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. Wherever possible, water supplies in emergency conditions should ...be obtained from underground sources by exploitation of springs, tubewells, or dug wells. No filtration will then be needed. However, if sources are not available or cannot be developed, the use of surface water from streams, rivers, lakes or ponds becomes necessary. Usually these surface sources are polluted. The level of faecal contamination can be measured by use of the Oxfam/Delagua Water Test Kit (see Section C). Where a serious level of faecal pollution exists, it is essential firstly to try to reduce the cause of contamination, and secondly to treat the water to make it suitable for human consumption. The Filtration equipment provides a simple, long-term physical and biological treatment system that requires no chemicals (except small amounts of chlorine required during filter cleaning) and needs only simple regular maintenance

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.

A septic tank takes raw sewage in, allows the solids to settle (sludge) and allows the remaining liquid to flow into the surrounding soil by means of a soakaway. Scum on the surface is also prevented from leaving the tank. Microorganisms in the anaerobic environment in the tank digest the sludge and... scum. The system consists of several stages, supply to the tank, the tank itself and the soak field.
