    I am developing a modular biosand water filter made from 2-gallon and 5-gallon
    plastic paint buckets. The buckets are made of food-grade (number 2) polyethylene
    and are the same buckets you can find at most hardware stores worldwide. I believe
    my modular water filter meets all of the critical design requirements of the
    biosand filters developed by the CAWST.

    Please visit my work-in-progress page, link below, for details.


    I am also developing some scaled down filters to be used as rapid deployment
    options for treating water in desperate situations (Haiti and Pakistan).

    Please take some time to examine these DIY water filters.

    Please note, I am not selling anything. I am freely sharing information
    with anyone concerned with the safe water crisis.

    Your comments will be highly regarded.
