The plot I am talking about is in Makurdi, Benue State.

prosperdev:
This report is simple. It means you should locate the nearest stream or river if you really need water

emmy4real94:
Lol do u know that you pay for the agreed meters before they start working? And if they reach the point where u paid for and there is no water, they will begin preparing to pack up

99thEnemy:
It was carried out on the 5th of this month.

Good day everyone.

I need advice from people here who have real experience with borehole drilling.

I carried out a geophysical survey on my plot this month, March 2026 , to determine the best location for a borehole. The survey suggested two possible spots: Point 2 and Point 6, and the recommended drilling depth for both spots is 160 meters.

However, from my layman understanding of the report, it seems like water may be available at a shallower depth than 160m. I may be wrong, which is why I am posting here for expert interpretation.

Attached is the survey image so that those who understand these readings can help explain whether 160m is truly necessary or whether water can reasonably be gotten at a lower depth, especially at Point 2 or Point 6.

I was given the following drilling quotations:

₦17,000 per meter using 8 bar PVC casing
₦18,000 per meter using 8 bar PVC casing

I was told that the difference between the ₦17,000 and ₦18,000 rates is the casing thickness, although the exact diameter and wall thickness were still not stated clearly.

I was also given another quote of:

₦24,000 per meter using 10 bar PVC casing

But again, the diameter and wall thickness were not stated.

I also asked how much it would cost if they do only the drilling/punching, while I buy and supply the casing myself. I was told that drilling/punching only would cost ₦14,000 per meter for the 160m depth.

I want to ask the experts here:

1. Looking at the survey image, does it truly mean I need to drill to 160m at Point 2 or Point 6, or is it possible to get good water at a lower depth? I recommend you drill at point 6 and drill to maximum depth of 150m plus or minus 10m.

2. Am I misreading the report where it seems water can be found earlier? Water can be found along different points but point 6 has a better yield advantage cos the wall can be recharged even from 60m. U can even choose to terminate your drilling at 60m and you will be fine just for personal usage.

3. Does a recommendation of 160m usually mean that is where the best aquifer is, where the cleanest water is, or that shallower water may not be reliable? The recommended depth here will ensure that your borehole yield can be moderate to high yield and you shouldn't have any fear of seasonal variations.

4. Between 8 bar and 10 bar PVC casing, which one is more suitable for a 160m borehole? Will they do a full casing? What is your terrain? This factor should determine an answer to this but and also depending on the type of pump to be used and risers to be attached

5. Since I was told the difference between the ₦17,000 and ₦18,000 per meter quotes is thickness, what exact thickness should I be asking for? Just get a good PVC screen/case

6. What exact PVC casing specification should I be asking for:
diameter, wall thickness, pressure rating, screen/slotted pipe spec, and brand/manufacturer? For a depth of 160m, use atleast HDPE PE100 PN10 pipe and install a 2hp submersible pump.

7. Is it a red flag for a driller to mention only 8 bar or 10 bar, and say one is thicker, without stating the exact diameter and wall thickness? Use 10bar please else your riser pipe will burst inside the well. Don't go for popular brands as most have been counterfeited. Let him get a reliable pipe.

8. If I decide to buy the casing myself, what exact specification should I request so I do not buy the wrong one?

9. Apart from casing, what other materials would I need to provide if I go with drilling only/punching only? Casing, risers, submersible pump, valves, joint kit, wires, ropes, etc

10. Is ₦14,000 per meter for punching only not unreasonable? Whats your location? If you are within Abuja, I can drill at 12k per meter for u. Depending on if diesel price remains as it is at the moment.

11. Is it better to let the driller supply everything, or is it safer to buy the casing/materials myself? You may leave d driller to handle everything with an agreement that should there be a failure due to substandard materials, he will replace it.

12. Between Point 2 and Point 6, which location looks more suitable based on the survey? Point 6 and all my references above has to do with point 6.

13. What other questions should I ask before agreeing to drill? What is the yield of the well? Ensure to use good materials and good submersible pump and also risers.

I do not want to make a costly mistake, so I would really appreciate advice from people who understand borehole drilling and casing specifications well.

Thank you.

I did one recently and they didn't ask me to pay for all the survey claimed depth before they moved to site but a deposit. I was there in person and stop them some meters after getting to a level of aquifer water and balance them up to the point I stopped them.

99thEnemy:
It is in Benue, Makurdi.

Let them drill aiming at the quoted 160m, but ensure to be there when they start installing the casing and count how many casings were used. Each casing is about 5m and then do the maths to arrive at the number of meters dug.

If they found water at 50-70m they definitely won't continue digging till they get to 150m. I'm not sure they can dig further than 20m once they hit water. So theres no issue.

The cheating might come in if you're not there when they're installing the casing as they can install 20 and say they did 30 if you were not counting.

Which area in Benue

99thEnemy:
Thank you very much for this.

Also, I am having concern about the distance away from the soak-away, is 10 meters OK?

Also, what is the current price that should be reasonable for punching at that depth. I am thinking of supplying the casing myself.

Also, for casing, what Diameter, Thickness, and Pressure (Bar) rating should I use?

Should I use a higher Bar down and continue with a lesser one towards the top?

Thanks for this.

How much do you think is a reasonable price for puncturing for 160m?

The person was telling me 14,000 naira per meter for just puncturing, which doesn't add up because the quote he gave was 17,000 per meter where he will be the one to provide the 8-bar casing.

I am thinking puncturing should be way way less.
