Safe water systems

From Akvopedia

Safe Water Systems is a water quality intervention that utilises chlorine treatment combined with safe storage to make drinking water safe. The intervention has three steps:

1. Point-of-use treatment with chlorine, purchased and produced locally.

2. Safe water storage in locally produced plastic or ceramic containers with a narrow lid and spigot to avoid recontamination.

3. Behaviour-change techniques including social marketing, community mobilisation, motivational interviewing and education.

These activities increase awareness of the link between contaminated water and diseases. The SWS has been implemented in 19 countries and research has shown a consistent reduction of diarrhoea in users of approximately 50 %.
