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” Pump and Blair Pump.
This manual describes the test drilling of a tube-well in Epworth, near Harare, Zimbabwe and the construction and fitting of a PVC casing and filter mechanism. It also describes the construction of a simple “Bailer-Bucket” pump and the head works at the head of the tube well. Of particular significance is the part played by the family itself by making the water raising device – a tubular bucket fitted with non-return valve and handle. The design of the “pump” is very simple and easily made within the home. The chances of continued operation and maintenance are this considerably improved.
