Hey! Tell me more about this BioSand Filter
I thought you'd never ask. And even if you didn't I'm going to tell you anyway!
A concrete box about 12" square and 1 Meter high with 3 layers of sand and gravel, a difusion plate and a lid. Designed so it can be easily made virtually any place in the world.
And look what it is touted to do.
I drank from one for the duration of my stay in Brooke's Point.
