TRANSCRIPT
HWTS/WSP Workshop of the International Network on Household Water Treatment and Safe Storage
Vientiane, Lao PDRNovember 2014
International Network on Household Water Treatment and Safe Storage-
focusing on the needs of the most vulnerable
Overview • Basis for household water treatment and safe storage (HWTS)
• WHO/UNICEF International Network on HWTS
• Important HWTS initiatives
• National policy development
• International Scheme to Evaluate HWT
• Linking with water safety plans
• Monitoring and evaluation of HWTS
• Integrated interventions
Basis for Household Water Treatment and Safe Storage
• Important interim solution for:– 780 million without access to improved drinking-water
– Billions without access to safe and reliable drinking-water
• Proven primary health intervention:– Reduces diarrhoea 32-42%( Clasen, et al. 2006;Waddington,et al. 2009)
– Included in UNICEF/WHO 7 point strategy for diarrhoea control (2009); WHO/UNICEF Global Action Plan to Prevent Childhood Pneumonia and Diarrhoea (2013)
• Optimizing benefits requires optimal choice, consistent and correct use by at-risk populations:– WHO recommendations on HWT performance (2011)
– WHO/UNICEF Toolkit for Monitoring and Evaluating HWTS (2012)

International Network on Household Water Treatment and Safe Storage
• Co-hosted by WHO and UNICEF, Communications by UNC Water Institute
• Over 140 participating organizations
• Phase II Strategy (2011-2016) aims to:– Support national policy and framework development– Strengthen evidence base– Evaluate and disseminate best practices– Realize tangible results in scaling-up
• Global Network targets address key areas of work
HWTS Global Strategy 2011-2016- Mission Statement -
To contribute to a significant reduction in water-borne and water-related vector-borne diseases, especially
among vulnerable populations, by promoting household water treatment and safe storage as a
key component of community-targeted environmental health programmes.
Facilitating National Policy Development
• Regional workshops and development of national action plans
– East Africa 2011: Ethiopia, Kenya, Rwanda, Tanzania and Uganda– Southern Africa 2012: Malawi, Mozambique and Zambia– West Africa 2013: Gambia, Ghana, Liberia and Sierra Leone – Asia 2013: Bhutan, Cambodia, India
• Focus on inclusion of HWTS in nat'l health policies
– Child and maternal health– Nutrition– HIV/AIDS and TB– Emergencies

Why Integration?-Greater health gains
• Antenatal Care in Malawi (Sheth, AN, et al., 2010; Wood, et al., 2011)
– Marked increase in antenatal visits, delivery in health facilities, and postnatal checks
– 30-fold increase in household water treatment 3 years later
• Zambia HIV+ mothers (Peletz, et al.; 2012; Peletz, et al.; 2013)
– Use of filters 96% among HIV+ mothers
– Significant reductions in diarrhoea in young children and the household
– Long-term high use sustained even after intervention ceased
• Kenya multi-disease campaign (Walson, et al.; 2013)
– Use higher in intervention vs control: 99.5% vs 76% (any method); 93% vs 0.4 % (filter)
– Significant reductions in diarrhoea and HIV mortality

International Scheme to Evaluate HWT
• Promote and coordinate independent and consistent testing and evaluation of household water treatment products based on WHO performance criteria; and
• Support national governments building technical capacity of research institutions and strengthening national regulation of HWT.
• Round I of evaluations currently underway
HWTS and Water Safety Plans
• Water easily becomes contaminated during collection and storage in the home (Wright et al.,
2004) AND piped supplies in developing countries are often not reliable or safe(Prüss -Ustün et al., 2014)
• HWTS provides an important mitigation measure to reduce risks associated with drinking-water in the home/school/care facility
• Many countries (Afghanistan, Democratic Republic of the Congo, Ethiopia, Kenya, Lao PDR, etc) working to holistically address water quality with WSPs and HWTS
