Principles and practices of drinking-water chlorination: a guide to strengthening chlorination practices in small-to medium sized water supplies.
AbstractThe WHO/AusAID (DFAT) Partnership for Water Quality and Health has been promoting Water Safety Plans (WSPs) in SEARO countries for more than 10 years. WSPs are designed to benefit all water users by ensuring improved water quality throughout a water supply system and are seen as a way of improving health and enhancing system sustainability. One of the biggest challenges for sustainable implementation of WSPs and delivery of safe water, especially for smaller systems, is good chlorination practice. WHO contracted a water treatment expert to help Bhutan and Timor Leste to improve their chlorination through the delivery of a tailored training programme and the development and implementation of supporting standard operating procedures. These are both countries with small urban water supplies being managed by small utilities with fairly limited capacity, so are representative of so many water suppliers across the region. This training and the SOPs were well-received in both countries and the SOPs are simple and clear but comprehensive so these are now published in response to a growing demand for supporting training materials and manuals for this technical area.

Montiel, Antoine; Bonnefoy, Xavier (1996)Each year, 3 million people throughouth the world die as a direct result of drinking unsafe water. This colossal figure is particularly worrying when seen in conjunction with the 120 million people in WHO's European region who do not currently enjoy an uninterrupted supply of microbiologically safe drinking-water. Local authorities have the prime responsibility for eliminating this risk and dealing with instances of contamination which, even when minimal, may result in catastrophic epidemics. It is up to them to do everything in their power to ...
