Drilling in Ifite, Awka Anambra State.

Drilling in Awka generally does not involve so much technicality as the targeted aquifer is not that deep, like between 90 - 150ft. The formation here is majorly of sands.

But Ifite area, especially around Unizik campus gate 3 area is an exception. In this area, getting water is very difficult because there is an extension of Enugu coal and Imo shale passing through it. We only have sands from the top down to like 10-20m and after that, it is coal/shale extending to like 1000ft(from previous drilling)

Hand dug well cannot be drilled pass this coal/shale formation thereby limiting the aquifer being tapped from to the top sands (less than 20m).

Drilling for water in a situation like this is not that tough but drillers should be well prepared for loss of circulation. To combat this wont be that easy considering the thickness of the coal or shale.

Attached are the result of my investigation in the area.

olawale100:
I am based in Nigeria.

His own is not a case of fraud but it is a case of ;

1. Irresponsibility - Abandoning site and duty.

2. Misinformation - Not specifying the type of drilling (Hand drill) and mixing (hand mix as against concrete mixer) method

3. Unprofessional - Subcontracted the job without ensuring the project is seen through.

Like I mentioned, I had paid 78% of project cost, and the balance 22% was used to pay the drillers. The project cost me more eventually I had to pay for concrete mixer for 7 days and paid for casting of 12 pile points. My finger was burnt but not so much. If I did not know one or two things about buildings, I would have been dealt a bad blow.

I actually sent a mail to him that I will post on Nairaland.

Sir, what happened is so unfortunate!

I think what causes all this is lack of contract terms...the two of you didn't define how the project will flow. You actually overlooked this thinking its a small project.

I think you should have used the contract terms to open up a good communication on the project flow.

Now in his own mind, he has calculated using hand drilling, i dont know if that reflected in the quote he submitted. You changing his tactics to motorize drilling could have destabilized him.

But he, on his part should have informed you of the changes that could occur as a result of this and possibly ask for a contract variation instead of the hide and seek game, or just backed out. but money is not easy to refund back, he would have spent a lot on logistics.

What i see is actually misunderstanding, lack of communication and clear terms.

@spyder880, these steel stanshions has proven to be the best practice for decades now but they are a lil expensive.

Another thing is to go for the galvanized which is relatively cheap but will provide the required strenght needed.

Using stand alone concrete is also good if its done properly. But it seems to be of old fashion.

Bros which one bi rubber again, to my knowledge most tanks are made with plastic oh, expect those of metal steel. Abi Naija done invent something better with rubber?

They were actually supposed to be produced as a rubber so as to be able to withstand enough stress and variable temperatures. but u know nigeria now...there will always be a second product.

The plastics are the lower grade, they break easily being of a brittle nature.

Drilling in Imeko.....The top soil is made up of a hard highly Ferruginised laterite, about 80ft in thickness. you can spend 2days on this alone depending on the rig you are using.

After this, be prepared to enter into a very loose units of kaoline and sand. This is what you will be drilling till you reach about 150ft.

At around 150ft, you will meet an aquifer, but you shouldn't rely on this. There is another hard laterite confining another aquifer beneath. The best practice is to penetrate through this hard laterite. This helps you to be on a safer side and also could give you an artisan hole.

Try and go deeper through the laterite then into another loose sand and clay.
At this level, you can confidently terminate the hole at around 200ft. If you have enough strenght, you can move to 250ft to create enough reservoir and to allow enough space for your pump to sit.

All the best!

Do u probe an open hole or just place on d floor and send down signal?

yea, its nt radioactive....it can only detect radioactive element in the subsurface and it dont have to come in contact with anythn b4 measurement is made thereby making it useful in both cased or uncased hole.
