Click here to provide anonymous feedback on this newsletter

Dear Colleagues,

We hope that 2013 is off to a great start for all of you. Did you know that this is the United Nations International Year of Water Cooperation? This should be particularly meaningful from the perspective of all of us involved in the HWTS Network – one of the aims of the Network is to foster collaboration and knowledge sharing among its members in order to achieve a multiplier effect in support of scaling up HWTS efforts. In this vein, we are sharing with you a brief 4-page overview of the Network activities from 2012, which you can download here. Many of you contributed to the Network’s achievements which reflects the spirit of this year’s UN theme.

As we move forward in 2013, we welcome your continued questioning, commenting, and contributions to Network activities. If possible, please consider setting aside a bit of time to assist other Network members with less financial and technical means. Finally, you may even wish to put forward an idea of your own as a Network product or make a submission to our newsletter. Contact us to share your thoughts!

In this newsletter, we have also added a new feature to poll you on your thoughts on Network activities. In this issue our question is related to planning a couple of upcoming webinars. We hope that you’ll participate and let us know what topics interest you.

Finally, our colleague Dr. Su Latt Tun Myint at the Department of Medical Research for Lower Myanmar recently won the Young Researcher Award at the 41st Myanmar Health Research Congress held in January. Congratulations to her! You can learn more about her paper below in the “News and Newsletter” section.

Best regards,

Ryan Rowe
Network Communications Officer

Although the Vhembe Water Filter is not currently being manufactured, the CAD models available in our collection will allow others to further the design into manufactured prototypes (and thereafter possibly tooling for production). The sketch portfolio may assist others who are exploring alternative solutions to problems encountered in the rural setting. Links to the dissertation allow for others to read through and understand the entire process of field research, data gathering, data analysis and the development of a solution to suit the intended users. University researcher Martin Bolton asks that we share this resource widely. Access the collection

Water Institute at UNC: Requesting water quality studies

The JMP post 2015 Water Working Group is conducting a review of the safety of improved sources of drinking water sources and would like to offer you the opportunity to submit information for consideration.

The study, being conducted by the Water Institute at UNC, focuses on priority health related contaminants as identified by the JMP Taskforce on Monitoring Drinking-Water Quality, namely arsenic, Escherichia coli (or thermotolerant coliform) and fluoride, and covers the following questions: (1) Is water from improved sources more frequently compliant with health guidelines than water from unimproved sources? (2) Are compliance levels consistent between and within countries? (3) Are some types of improved water source associated with higher levels of contamination or sanitary risk?

If your organization has conducted studies that could inform this review, please contact Robert Bain (

Stories from the Field

By Ryan Rowe: Commercial approach to ceramic filters in Ethiopia

During a recent visit to Addis Ababa, we met with Tulip Addis Water Filter, a private company selling ceramic water filters in Ethiopia since 2010. Its product, known as the “Tulip” water filter, is a siphon device with a ceramic element. The company reports a brisk business in meeting the programmatic needs of local and international NGOs, with sales across all nine of Ethiopia’s regions and total volume of approximately 60,000 filters a year.

The filter, manufactured by Network member Basic Water Needs of India, is sold by other companies in at least half a dozen countries around the world, including Malawi and Mozambique where it has recently been introduced by local entrepreneurs. Depending on distribution and marketing costs, the retail price tends to range from US$15 to US$25.

Although considered a relatively low-cost product, Tulip Addis General Manager Getaw Cherinet acknowledges that his filter is still unaffordable to many low-income earners. “Most of my customers are actually NGOs who give away the filters or sell them at reduced prices in order to better serve populations in need”, he says. In order to lower the retail cost further, the company has plans to build a factory and produce the ceramic element locally, in partnership with the manufacturer. With the additional production capacity, the company plans to expand into other East African markets and introduce a table-top version of the filter to make it more aesthetically pleasing and user-friendly. An added benefit of investing in a local production facility is to improve the availability of spare parts. Getaw also mentioned that he recently partnered on a proposal to evaluate the use of targeted vouchers to stimulate purchase by low-income families, an innovation which has been discussed at recent Network events.

The Tulip filter has a useful life of about 7000L of drinking water and can produce filtered water at a flow rate of about 5 litres per hour. Although no peer-reviewed studies have been published on the microbiological effectiveness of the device, Tulip Addis Water Filter says their product has been approved by government authorities prior to introduction to the market. Getaw agreed that having independent researchers monitor and evaluate his product’s performance in the field and publish the findings in a journal would be a useful addition to the evidence base and help him better market his product. He welcomed researchers who might be interested in such a study.

Getaw also shared his view on key challenges to doing business in the Ethiopian market. “There is a foreign currency shortage in Ethiopia”, he says, “This makes it difficult for vendors to obtain bank-guaranteed letters of credit with which they could purchase at higher volume from overseas. This is one of the main incentives for me to invest in a local production facility.” In addition, he reports that his clients often face funding constraints or delays making it difficult for him to reliably predict sales volume and forecast inventory requirements.

Recent Events

African Leadership on Child Survival, January 2013

In an effort to catalyze global action for improved child survival, the Governments of Ethiopia, India, and the United States together with UNICEF held the ‘Child Survival Call to Action’ in Washington DC, USA. in June 2012. Under the banner of ‘Committing to Child Survival: A Promise Renewed’, more than 160 governments signed a pledge to renew their commitment to child survival, to eliminate all preventable child mortality in two decades. Progress toward this goal was reported by UNICEF in September 2012.

To maintain the momentum created by the June meeting of leaders, the Government of Ethiopia convened the African Leadership for Child Survival—A Promise Renewed” Meeting January 16-18, 2013, in Addis Ababa, the seat of the African Union. The meeting brought together leaders from African countries. View the agenda

Some clear decisions emerged from the discussions described in this summary of Key Messages, an output of the meeting. Three key actions are prioritised: 1) evidence-based country plans, 2) transparency and mutual accountability, and 3) global commitment & social mobilization. In addition, a roadmap was created with emphasis on several high impact solutions to improve child survival. Our work in household water treatment and safe storage (and by extension improved access to safe water) has clear links to at least three of these solutions: reducing stunted growth through improved nutritional status, prevention of mother-to-child transmission of HIV, and social/behavioral change for improved health. Through workshops, publications and our communications activities, the Network aims to provide you with the information to integrate HWTS effectively into your program planning (or that of your partners) to achieve these health objectives and the overall goal of improving child survival. If you need further information or guidance, please contact us.
