After the concrete of the toilet box is completely dried out, one can fix the two handles at the side walls of the box. If doing the constructing in sandy ground, this can happen already in step 1, when placing the handles upside down in the sand in the form of the two side walls. The two handles will serve for moving the toilet box away from the top of the improved pit latrine, once the pit will be full (a 3 - 4 m deep pit should take about 3 years to be filled by a medium African household).
