THE HWTS Global Strategy 2011-2016
- Mission Statement To contribute to a significant reduction in
water-borne and water-related vectorborne diseases, especially among
vulnerable populations, by promoting
household water treatment and safe
storage as a key component of communitytargeted environmental health programmes

evidence base of the public health relevance of household
water treatment and safe storage significantly
strengthened;
tangible results in the scaling-up of household water
treatment and safe storage achieved in countries in all
regions of the world;
national policies and institutional frameworks developed
and in place to ensure the integration of different
environmental health interventions with drinking-water
treatment and safe storage at the household level from a
broad public health perspective; and,
best practice in HWTS programmes evaluated and
disseminated for advocacy purposes.
Kuching, November 2010
THE HWTS Global Strategy 2011-2016
- Targets By 2015, 30 countries have established
policies on household water treatment and
storage.
By 2015, strengthened evidence to guide
effective and replicable HWTS programmatic
approaches to achieve long-term widespread
use and public health impact.
By 2020, 50 countries have achieved countrywide scale up of project-based HWTS.

THE HWTS Global Strategy 2011-2016
- WHO policy development 26. The high initial capital costs and long time frame associated with
implementing centralized treatment and distribution of drinking-water
may exclude many communities, particularly in poor rural areas, from
the health benefits of a piped water source in the immediate future.
Household-level water treatment and safe storage are additional steps
that can be taken immediately where and when “improved” water
sources do not deliver consistently safe water or where safe water is
available only intermittently. Together they form one component of a
seven-point plan, jointly agreed by WHO/UNICEF, to reduce
diarrhoeal disease mortality. Working with partners, including with the
WHO International Network to Promote Household Water Treatment
and Safe Storage, established in 2003, the WHO Secretariat
encourages correct and sustained application of household water
treatment and safe storage where water is not reliably safe. The
Secretariat provides support to countries in formulating policies and
devising programmes on household water management and
establishing criteria for the evaluation of technologies for treatment of
household water so that implementers, donors and users can select
appropriate and effective methods.

THE HWTS Global Strategy 2011-2016
- WHO policy development 8. Although the management of water resources is
crucial, access to safe water sources needs to be
improved and sustained, along with promotion of
household-level water treatment and safe storage
in order to prevent occurrence of cholera and to
reduce morbidity in case of outbreaks. Even
households that have access to improved drinkingwater sources may suffer from recontamination
within the home, requiring specific action to prevent
exposure at that level.

World Health Assembly in May 2010, on Strategies
