After we wrapped up the model shoot in Tanzania, our team had a chance to work one afternoon at the workshop where the bio-sand filters are constructed on a daily basis. If you haven't already read the post I did a few days ago about how these things work, definitely check it out here.

Here's a shot of some of the guys who work day in and day out at the workshop:
Our team each took different stations and jumped right in. Here's Jason Thon and Ben Harrison preparing the cement molds:

Here are a few shots of Phillip Glickman preparing the molds. Check out the bicep in that top right shot!
