A borehole for a house in Tanzania typically costs about TSh 6 million to 20 million (about USD 2,300 to 7,700) in 2026, including the hydrogeological survey, permit, drilling, casing, pump and a storage tank. The biggest factor is depth: shallow boreholes in parts of Dar es Salaam may be 30 to 80 metres deep, while dry or rocky areas can need 100 metres or more. Every borehole needs a water use permit from the Basin Water Board for the area, and the water should be tested before you drink it.
What does a borehole cost, item by item?
| Item | Example cost |
|---|---|
| Hydrogeological survey | TSh 500,000 to 1,500,000 (about USD 190 to 580) |
| Basin Water Board permit and fees | Set by the board, check current rates |
| Drilling and casing, per metre | TSh 60,000 to 150,000 (about USD 23 to 58) |
| Submersible pump, installed | TSh 1,500,000 to 4,500,000 (about USD 580 to 1,730) |
| Solar pumping system (instead of mains power) | TSh 3,000,000 to 8,000,000 (about USD 1,150 to 3,100) |
| Elevated tank and stand, 5,000 litres | TSh 2,000,000 to 4,500,000 (about USD 770 to 1,730) |
| Water quality test | TSh 100,000 to 300,000 (about USD 40 to 115) |
Example prices only. Costs vary a lot with depth, geology and region. USD figures are approximate, using roughly TSh 2,600 per USD.
Why do you need a survey before drilling?
A hydrogeological survey uses the local geology, nearby boreholes and often a geophysical test to choose the best spot and estimate depth. Drilling without one risks a dry or salty borehole, which costs almost as much as a good one.
Do you need a permit to drill a borehole in Tanzania?
Yes. Groundwater is managed by the Basin Water Boards under the Ministry of Water, for example the Wami/Ruvu Basin in Dar es Salaam and Coast. Drilling without permission and paying the fees can lead to fines. The usual process:
- Apply to the Basin Water Board for a drilling permit, with the survey report.
- Use a registered drilling contractor.
- Submit the drilling records after the work.
- Hold a water use permit and pay any annual charges.
How deep will my borehole be?
| Area type | Typical depth range |
|---|---|
| Coastal sandy areas | 30 to 80 m |
| Inland plains | 60 to 120 m |
| Rocky or dry highlands | 100 to 200 m |
Typical ranges only; your survey gives the estimate for your plot. Coastal boreholes can be salty if drilled too deep or too close to the sea.
Is a borehole better than a DAWASA or RUWASA connection?
| Public water connection | Borehole | |
|---|---|---|
| Upfront cost | Lower | Higher |
| Running cost | Monthly bills | Power or solar, maintenance |
| Reliability | Depends on supply | Good if the borehole is well sited |
| Water quality | Treated | Must be tested and sometimes treated |
| Permits | Utility process | Basin Water Board permit |
Many homes use both: the public supply when available, plus a borehole or rainwater tank as backup. Contact DAWASA in Dar es Salaam or RUWASA in rural areas for connections.
How do you keep a borehole working?
- Service the pump every year.
- Keep the borehole head sealed and raised above flood level.
- Test the water at least once a year.
- Do not over-pump in the dry season.
Frequently asked questions
How much does it cost to drill a borehole in Dar es Salaam?
Often TSh 6 million to 15 million (about USD 2,300 to 5,800) for a house, including pump and tank, depending on depth.
How long does it take to drill a borehole?
Drilling itself often takes one to five days. With the survey, permit and installation, plan for several weeks.
Can I drink borehole water?
Only after a laboratory test shows it is safe. Some water needs filtering, softening or disinfection.
What if my borehole is dry?
Most contracts still charge for the drilling done. A good survey reduces the risk, and some contractors offer terms for dry holes; agree them in writing.
