Hi Karl (and anyone else out there)
We are holding a biosand training in Machakos, Kenya this coming September. It will last 5 days and will go through both theoretical and practical aspects of making biosand filters. All details can be found on the training page on this website (http://biosandfilter.org/biosandfilter/index.php/item/337).
Cheers
Eric
