BiPu

BiPu (Bioremediation Infield Personnel Unit) is a sanitation method suitable for disaster relief and for temporary or isolated locations. It consists of flat-packed plastic panels which fit together to make a box, which is buried in the ground, and a large plastic bag to be placed inside the box. It is quick to set up but also suitable for longer term use if required.

A latrine, (Western style, or Asian squat style) pour-flush latrine, is placed over the top. The water seal improves hygiene, compared to pit latrines.

The box is open at the bottom so that rising water tables do not damage the BiPu.
