The construction of the lighter duty, simple hand operated drilling rig has been described in another manual and was designed for drilling shallow tube wells in softer soil formations, which occur in some areas of Zimbabwe. Currently the drilling stems extend to a maximum of 12m. Staff members of the Ministry of Health and Child Welfare are familiar with local shallow ground water conditions in Zimbabwe. A depth of 12m is suitable for the use of this simple rig in combination with simple water raising devices like the Bailer-bucket, Bucket Pump and Blair Pump.
