Kevin’s been missing all the beautiful weather (yes, it DID hit +20) . . . he’s taking a professional development course this weekend. The course is all about Biosand Water Filter construction and implementation for overseas applications . . . so some theory as well as very hands-on sieving sand and hand-mixing concrete. Here’s Kevin preparing the form for the concrete pour:
It’s an amazing mix of people at this course, from all over North America . . . all who work with water-quality issues overseas. I think they’ve been having as much fun swapping stories as building the filter. The course is done Monday, so we’ll try to get a picture of the finished filter. These filters are designed to be built on-site with local labour and local materials for use inside individual homes . . . and they’re very effective. They produce potable water from just about any contaminated source. If you’re interested in more info about the filters, check out the CAWST Website . . .
