Slow sand filtration is a filtration system for relatively small scale waterworks. Since it is cheaper to install and maintain than rapid sand filtration which is current mainstream in Japan, it can be more suitable for developing countries depending on the conditions.
The Japan International Cooperation Agency (JICA) has produced a multimedia-based learning package “Slow sand filtration: creating clean, safe water” in English and Japanese, consisting of a video and reference materials.
The video (26 min) can be viewed in 6 parts. Parts 1-5 provide background information on large-scale and small-scale application of slow sand filtration technology in Japan. Part 6 is about a JICA project in Sierra Leone.
The reference documents are on an introduction to Ecological Purification System [5.7 MB] (new concept and new name of slow sand filtration) and a report on the Water Supply Management System in Kambia District project [15.6 MB] in Sierra Leone.
Dear web manager,

By the way, I will visit the UNESCO-IHE (Delft) on May 24 (Monday) 2010. I will present a short talk (about one hour) at Univ. College of London on May 12, 2010 and I will present another talk at Univ. Glasgow on May 17. On the wayback from UK to Japan, I will visit Dr Kebreab Ghebremichael,

Thanks for the update, the link has been updated. Regards to Dr Kebreab Ghebremichael, I was impressed by his pioneering work on large-scale application of natural coagulants especially Moringa oleifera.
Has there been any updates on this project from the JICA?
Slow sand filter problem in Samoa was solved by ecological point in 2010.
