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
