Household Water Newsletter, Issue 20

Dear Colleagues,

Thank you to all those who expressed interest in participating in the soapbox session at the upcoming Annual Meeting on 29 October. Of 20 submissions received, 8 were selected and you can learn which ones in this newsletter. Later this month we will release the agenda of activities for the Annual Meeting so please keep your eyes peeled for that. And YES, same as last year and the year before, we will have another happy hour / networking cocktail at the end of the day. We can’t wait to see some of you again and meet others for the first time!

Many of you have been involved or following the progress of the Monitoring & Evaluation Toolkit. The document is now in final form and being prepared for release before the end of the year. In addition, the Network Secretariat with other partners are preparing a series of briefing notes on HWTS for policy-makers and practitioners. So far, notes have been prepared on the integration of HWTS into HIV/AIDS prevention and care and the role of HWTS in emergency response efforts. We hope to share these with you soon.

We also have other good news – our friends in Latin America – Ecofiltro, a social enterprise working on HWTS in Guatemala, have won a Schwab Foundation Entrepreneurship Award! Felicidades!

Don’t forget that the Network offers various channels through which you can share your work with the HWTS Network community, such as through a guest blog posting, an announcement in our monthly newsletter or via our twitter feed @household_water! Please email us your news and updates at

Best regards,

Ryan Rowe
Network Communications Officer

  • HWTS Network Secretariat: Network Meeting soapbox selections announced
  • In July the Network Secretariat released a call for expressions of interest to participate in a soapbox session at the upcoming Annual Meeting on October 29. Twenty submissions were received from which 8 were selected for the final line-up. We used three criteria in the selection process: 1) that the proposed submission clearly addressed at least one of integration, innovative financing, behavior change, scaling-up or sustainability; 2) that it made a contribution to current knowledge/understanding; and 3) that the submitting individual or organisation had shown previous involvement in Network activities. Here is a brief list of the selected presentations:

    – Hans Mosler, Eawag | Using the RANAS Model of behavioral change to explain safe drinking water practices
    – Laura McLaughlin, Cascade Designs | Electro-chlorination in schools in USA and Kenya
    – Michael Ritter, Deep Springs International | Commercial distribution models for HWTS in Haiti

    Discussions and Requests

  • HWTS – A failed public health strategy?
  • Steve Luby, a senior fellow at Stanford University, recently asked whether household water treatment is a failed public health strategy. Although many methods deliver improvements in water quality, study methodologies need to be improved and there are still questions of sustained health impact and how to best reach and encourage uptake in the populations that need it most. He proposes that HWTS needs a radical improvement and greater attention needs to be paid to system-level interventions. What do you think? Join the discussion

  • Poor taste and bad smell of water from BSFs
  • Did you know about the Bio-sand Filter Production Group? This Google Group encourages discussion on issues related to bio-sand filters. Over the last week or so, there has been an interesting conversation about the poor taste and bad smell of water from bio-sand filters in hot tropical climates.

    Recent Events

  • Network Workshops on HWTS Strategies and Policies, June 2011 and 2012: Update from Kenya, Malawi and Zambia
  • In June 2012, WHO and UNICEF convened a workshop to aid the governments of Malawi, Mozambique and Zambia in advancing the use of HWTS in the fight against diarrhoeal disease. The year prior, a similar workshop was held focusing on Ethiopia, Kenya, Rwanda, Tanzania and Uganda. WHO and UNICEF have committed to providing a small amount of seed funding to aid these efforts in moving forward.

    Kenya: The Government of Kenya has several technical working groups tackling policy issues around water and sanitation related areas, including household water treatment and safe storage. At a recent meeting of the National Environmental Sanitation & Hygiene Inter-agency Coordinating Committee, the Technical Working Group on HWTS mentioned several initiatives to strengthen HWTS planning of which three are: 1) mapping of stakeholders at the national and regional levels; 2) adapting the 2011 WHO-produced performance recommendations on evaluating HWTS options for the Kenyan context; and 3) developing a national strategy for HWTS.

    Malawi: The Government of Malawi recently submitted an outline of its national action plan to WHO and UNICEF and was provided with seed funding to enable the hosting of stakeholder consultations. In addition, based on promising emerging results from studies in Blantyre, Salima and Machinga over the last several years, Malawi’s Ministry of Health is currently considering whether and how to expand implementation of a program that uses water-related hygiene products as incentives to increase uptake of maternal health services. Below is a photo of a Ministry of Health official discussing the considerations with the Committee on Safe Motherhood, a group of government and non-governmental experts on maternal health in Malawi.

    Zambia: The Government of Zambia recently submitted an outlines of its national action plan to WHO and UNICEF and was provided with seed funding to enable it to move forward with a situation analysis of HWTS in provinces prone to epidemics of water-related disease.
