Household Water Treatment and Safe Storage:

The Chlorine Chemistry Foundation® is helping to promote the use of simple, low-cost technologies to disinfect and safely store water for household use. These technologies can provide tremendous public health benefits to the more than 1.1 billion people who rely on water from unsafe sources. While the ultimate goal should be safe water piped to every home, household water treatment, together with safe storage, is an effective and immediate solution.

A growing body of research demonstrates that point-of use treatment with chlorine disinfectants dramatically improves the microbial quality of water and can reduce the risk of diarrhoeal disease by 25-50%.


WHO's Household Water Treatment Network:

Promoting simple, low cost water technologies on a global scale

The Chlorine Chemistry Foundation is helping to promote the widespread adoption of household water treatment and safe storage by supporting a network of organizations implementing various projects around the world. Organized by the World Health Organization, the International Network to Promote Household Water Treatment and Safe Storage (The Network) includes a diverse group of humanitarian relief organizations, government agencies, research institutions, and the private companies. Through the Chlorine Chemistry Foundation, World Chlorine Council member associations provide financial support for Network activities, including:

  • Independent research to evaluate technologies and practices,
  • Communications among members and other stakeholders,
  • Advocacy to educate decision makers and funders about household water programs, and
  • Sharing tools and information to improve project implementation.

Household approaches, including treatment with chlorine-based disinfectants, have been shown to be extremely cost effective, rapidly deployable, and can lead to significant health gains. We encourage the World Chlorine Council to remain active and contributing to this important area.

Safe Water in Bangladesh:

Combating Diarrhea with a Household-based Water Treatment and Storage System

The Chlorine Chemistry Foundation has supported the pilot testing of a community-based implementation of the Safe Water System (SWS) among residents of Baoniabad, a slum community comprised of 2,600 families in Dhaka, Bangladesh. The project is coordinated by the CDC Foundation, an independent, non-profit enterprise that forges effective partnerships between the U.S Centers for Disease Control and Prevention (CDC) and others to fight threats to health and safety.

In Dhaka, the capital of Bangladesh, nearly 90% of source water samples in one neighborhood were found to have been contaminated with fecal coliform bacteria and Escherichia coli. Contamination rates were even higher in stored drinking water samples inside homes. By implementing the Safe Water System among residents of Baoniabad, the CDC Foundation aims to increase awareness of how diarrheal disease can be prevented, and to evaluate the acceptability of in-home chlorination and storage containers among Bangladeshi families.

The project is being implemented by a locally-based non-governmental organization with a strong history of commitment to the Dhaka slum population. The intervention includes delivering behavior change messages related to water and health, in-home chlorination of water with a locally-produced sodium hypochlorite solution, and promotion of safe containers for water storage.
