SHIPO Tube Well Drilling
Southern Highlands Participatory Organisation (SHIPO)
Southern Highlands Participatory Organisation (SHIPO) Tube Well drilling is a manual drilling technique that combines percussion, sludging and jetting.
SHIPO Tube Well Drilling is a labor-intensive baptist drilling technique combining percussion, sludging and jetting techniques. It is supported and operated by a local Tanzanian NGO called Southern Highlands Participatory Organisation (SHIPO). To date, 300 wells up to the depth of 45 m have been dug by applying this method, which is further combined with locally produced rope pumps. SHIPO claims to be cheaper than traditional and machinery methods of borehole drilling because it can be operated by local people and the materials for the manual drilling and rope pumps can be acquired locally.
This product is currently being distributed in Tanzania and Malawi. However, SHIPO is aiming to also distribute the product in countries like Angola, Burkina Faso, Congo, Mozambique, Zambia, and Zimbabwe.
This product is being implemented by 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 drill holes up 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.
Goal 6: Clean water and sanitation
This technology is suitable for communities or self-supply wells at the family level.
This product is built on-site with locally sourced construction materials. The drills are assembled by SHIPO trained technicians. For building a pump or drilling a borehole, SHIPO employs coaches who are normally selected from the community.
Trade Secret available for licensing and local manufacturing.
Village communities and families can get SHIPO drill installed via trained and certified local SHIPO dealers.
As of 2020, 800 tube wells (depths 20-48 m) have been drilled in Tanzania, Malawi, and Mozambique.

The SHIPO drill is based on the Baptist Drilling method 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. Any broken 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. Percussion action is performed by lifting the drill stem with a rope over a pulley, attached to a simple derrick, made with whatever available that is usually either 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 favorable 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
Schematics provided by SHIPO drilling
SHIPO trained technicians provide support.
Drill components are locally sourced and thereby readily available.
Manufacturers specify a maximum drill depth of 60 meters deep.
No third-party organizations, only testing performed by the designer.
Some of the safety measures users must consider while using such hand drilling methods include:
- Roping off the job site to notify bystanders from wandering around the drilling site.
- Avoiding rusty pipes and drill bits that can cause infection to preexisting cuts.
- Replacing the thread protector caps before storing pipe in a trailer.
