JAKARTA, Sept. 15 (Xinhua) -- A study that offers ceramic water filters as a sustainable solution for rural drinking water treatment in Cambodia, has won the International Water Association (IWA) 2008 Project Innovation Award Grand Prize for Small Projects in Vienna recently, a release by the World Bank Indonesia said.

    According to the release received by Xinhua on Monday, the study is funded by UNICEF and the Water and Sanitation Program and implemented by the University Of North Carolina School of Public Health.

    The goals of the study were to characterize the microbiological effectiveness and health impacts of the ceramic water purifier, a household-scale ceramic filtration technology, in target populations and to identify successes and potential challenges facing the scale-up and implementation of the technology.

    Results from the study suggested that the filters could significantly improve household water quality, offering up to 99.99 percent less E. coli in treated versus untreated water, said WSP Cambodia Senior Water and Sanitation Specialist Jan-Willem Rosenboom.

    Ceramic filters have helped many families in rural Cambodia, especially those living in villages where the ground water has proven to be contaminated with arsenic. Using these affordable filters, families can use surface water for drinking and cooking while continuing to use their contaminated wells for other purposes such as washing and gardening, Dr Mao Saray, Director of Rural Water Supply, Ministry of Rural Development, Cambodia said.
