  • iDE Cambodia and Hydrologic: Ceramic water filter initiative wins award
  • A ceramic water filter initiative implemented in Cambodia by iDE Cambodia and Hydrologic was named a winner of the 2012 Ashden Awards. The Ashden Awards are presented annually to encourage the greater use of local sustainable energy to address climate change and alleviate poverty. This year, iDE/Hydrologic won the award for “avoided deforestation” because the filters effectively reduce the burning of wood and charcoal for boiling water. iDE introduced locally produced ceramic filters to Cambodia in 2001 with technical support from Potters for Peace. Hydrologic was spun off as a social enterprise in 2009 to deliver clean water products to rural customers, creating social and environmental benefits while being financially self-sustaining. From 2009 to 2011, Hydrologic received financial and technical support from WaterSHED Asia, a USAID-funded project led by the University of North Carolina Gillings School of Global Public Health, which aims to bring effective, affordable water and sanitation products to market in Cambodia, Laos, and Vietnam.

  • 300in6: Sponsoring a study on carbon finance for HWTS
  • 300in6, the Netherlands-based platform for enabling access to safe water by 300 million more people in six years, is conducting a study on carbon finance for HWTS and proximity services. It examines issues for a safe water professional, exploring verification and claimed avoided emissions. The report, due out this September, assesses the value and risks of carbon finance compared with other funding options. For more information please contact Carole de Bazignan ( who is leading this effort.

  • Lifesaver systems: New product launch and offer to collaborate
  • LIFESAVER systems, a UK manufacturer working in the water and sanitation sector since 2007, provides a range of point-of-use water treatment technologies that remove the need to store clean water through the provision of instant fast flowing filters. They are currently supporting WASH projects in 30 countries with 38,000 devices deployed in 2011. As a result of joining DFID’s Rapid Response Facility (DFID is the Department for International Development, the foreign aid arm of the British Government) they have developed a new product named the LIFESAVER cube which will launch this month. The team at LIFESAVER systems would also like to announce its interest in collaborating with other Network participants on pilot studies within key areas where point-of-use filtration can make an immediate difference, such as in refugee camps, flood-affected environments and areas at high risk from waterborne diseases.

    Field Report

  • Potters Without Borders: Technical Assistance to Somaliland Filter Factory
  • Problems with inadequate and low quality water supply cause serious problems in Somaliland. Safe clean drinking water has become a commodity, particularly so in more urban areas such as Hargeisa. Mined water is transported by water tanker and donkey cart for sale to most households.

    Consultants from Potters Without Borders responded to a request by the German Red Cross to increase production at the Biyo Miire filter factory which is administered by the Somaliland Red Crescent Society.

    During the month-long visit a new, larger, liquified petroleum gas-fired kiln was built using brick manufactured on site with local materials. Issues of work flow, improved filter qualities and factory process were addressed. These visits allow for valuable information exchange between remote producers and the international community of filter producers. Factory best practices and current innovations are discussed on a daily basis in order to bring to light real issues encountered in production.

    The Biyo Miire factory is enjoying a steady increase in demand for their filters and is becoming, under the guidance of the SRCS, a valuable asset in the battle against waterborne disease in the Somaliland region.

  • Kai Morrill, Potters Without Borders
  • Laboratory testing has revealed the effectiveness of ceramic pot filters in terms of their ability to remove water borne pathogens. How is it then, that field test results find varying effectiveness within individual families in terms of their effect on reducing water borne disease?

    The answer lies somewhere in between the process of production and the end user. It is apparent that the ability to produce a quality filter unit is not the ultimate goal in projects aiming to provide families with adequate clean drinking water. If care is not taken in the methods of distribution and dissemination of the technology, the filters may not have sufficient opportunity to become fully effective tools against waterborne disease.

    When developing a sustainable plan for the implementation of new filter projects significant emphasis is put on establishing a partnership with an independent monitoring agency. This relationship not only involves the testing of source and filtered water in controlled laboratory tests, but also collects data regarding household use. Valuable data is collected in these field tests, particularly in establishing how the filter is being used and maintained in the home.

    Models of filter distribution methods vary significantly, even within single distribution areas. A factory that retails its own product through door to door sales often displays a greater connection to proper filter use and maintenance, as opposed to wholesale distributors where a distributor organization may not have a reasonable plan in place to ensure the filter users are properly educated.

    Although the factory itself is oriented to maintain a high volume of sales, arguably, sales which result in ineffective filter use may reduce buyer confidence. It is in the factory’s interest to ally with partners who will ensure that proper practices for filter use are an integral part of filter sales because ultimately purchases are driven by demonstrable improvements in the health of the filter users. It is appropriate therefore, for the responsibility for proper dissemination to be shared with the agencies which implement the filter projects and NGO buyers wishing to utilize purchased filters in their programs. Partners should develop, monitor, and assess distribution methods in order to maintain competent results in disease reduction.

    President, Potters Without Borders
