Southern Highlands Participatory Organisation (SHIPO) is a manual drilling service and training provider. The SHIPO Tube Well Drilling methodology is a variant of the Baptist method which combines percussion, sludging and jetting depending on regional soil conditions to create boreholes for accessing groundwater. SHIPO aims to reduce costs with a do-it-yourself alternative to costly drilling rigs via reliable training, appropriate equipment, and drilling work to its customers. The aim of manual drilling is self-supply so that families can increase income through water for animals, irrigation etc.
The Southern Highlands Participatory Organisation (SHIPO), a Tanzanian Non Governmental Organisation (NGO) based in Njombe, Tanzania.
The cost of a complete SHIPO drill set to 40 meters deep is $500 USD. The cost of a hand drilled well and a pump can go up to $1,500 USD for a community of 150 people.
Diesel powered portable drill rigs, Village Drill, Hand digging
Village communities of approximately 250 people who need water for drinking water, sanitation, irrigation and livestock. This technology is suitable for communal wells or for self-supply wells at the family level.
Materials are found locally and the drills are assembled by SHIPO trained technicians. SHIPO uses Coaches who are normally selected from the community and work in those respective communities to assist SHIPO.
Trade Secret available for licensing and local manufacturing.
Village communities and families can get SHIPO drill installed via trained and certified local SHIPO dealers.
The SHIPO drill is based on Baptist drilling developed by Terry Waller of Water for All in Bolivia in 1993. The drilling process is continuous and the drill bit is normally not removed from the borehole until it is finished and the broken-up material is pumped to the surface in the drilling liquid (mud). The borehole diameter is kept as small as possible in order to remove a minimum of material and advance quickly. Percussion action is performed by lifting the drill stem with a rope over a pulley, attached to a simple derrick, made with whatever available wood or bamboo poles. The main drill tool consists of a length of metal pipe with an open drill bit combined with sludging. Extensions are standard PVC potable water pipes.No temporary casing is used. Drilling speed is variable with different soil conditions and crews, but over 15 m per day have been obtained in favourable conditions.
Casing diameter range is 2 to 6 inches.
Equipment length: 3 m;
Estimated weight of Rota sludge: < 200 kg; Shipo method (Baptist drill) is estimated to have max weight: 100 kg Interview with representative

Manual drilling Compendium- Rural Water Supply Network 2015 by DANERT K. not peer reviewed
SHIPO does not reference any regulations related to manual drilling. Designs of manually drilled boreholes vary between and within countries. African countries that provide key official parameters or where standards have been set include Chad, Guinea, Nigeria and Kenya. A comprehensive overview of specifications for Manually Drilled Wells and standards is available in the RWSN Manual Drilling Compendium (2015). There is scope for improvement, particularly with respect to design and borehole development.
SHIPO ensures long-term sustainability of its projects by combining infrastructure with thorough training and education, and by working in close cooperation with local authorities and leaders. SHIPO training includes a review (after a few months) by a SHIPO consultant to analyze the work of trained drillers and make suggestions to improve the work and/or the bore hole.
UNICEF’s Toolkit for the Professionalization of Manual Drilling has provided a step by step guide for those wishing to introduce manual drilling technology.
