Adding a pump for our borehole
After having done our borehole, it took us quite a while to set up a pump for it. It was challenging for us to save enough money for it, and find a good and reliable contractor. We have asked 4 different people. We received only 2 quotes. Once we knew more or less how much it would cost, we started saving for it. Once we were ready, we chose the contractor and got an updated quote that was 20% more expensive. To move forward, the contractor asked for a 50% payment to order the material. A couple of weeks later, the contractor received everything and he came with a colleague to set up the pump.
This is the list of material needed :
Submersible pump 21C 0.75 HP 230 V alanol, coverco engine
1 230 V electric level board
1 Cover for 11/4 fiber hole
90 meters of FVV pt cable 3x1.5
90 meters of 4x2.5 fvv pt cable
100 meters of PAD Tube 8kg 11/4
82 meters of Nylon rope
100 Buckle ties 120x 3.5 pt
1 Record ap/rap. 11/4x40 M
1 Ap/rap curve. 11/4x40 F
1 Brass union 11/4x1/2 F
1 1/2 Backyard Tap
1 Te ap/rap. 40x40x32 F
1 Prescontrol PS-01
3 Level probes
1 Heat shrink sleeve kit
1 11/4 check valve with stainless steel interior
2 11/4 brass bushings
First they had to set up the tubes, attach the pump and bring it down the borehole. Our borehole is 88 meters deep, and they installed the pump at about 82 meters deep, in order to leave about 6 meters above the bottom. This makes sure the pump will never get stuck with mud and other debris that may accumulate in the borehole.
Then they set up the balloon on top of the borehole, and added the faucet. Adding a balloon allows us to take water without having the pump working non stop. The pump works to bring water up and fill up the balloon. When we open the faucet, the water comes from the balloon, and the pump only starts to work again when the balloon is about to get empty.
Finally, they added the electrical board and tested the whole setup. It took them the whole morning, about 4 hours. Total cost of the material and labor to do the installation was almost 2000 Euros.
Now, April 2024, we can take water from our borehole! As expected, the water is really clear. It is really a big step for us, as we have been thinking and dreaming it for about 2 years.
But the whole borehole project is not entirely done yet. There are 2 big steps left :
Connect the borehole water to our house. For that, we need someone to come dig the line between the borehole and the house main door as its electrical board is located right next to it. Then we need to dig into our house wall so that the wire can reach the electrical board, and connect both.
Install a water tank next to the borehole and set up all the necessary filters. We think the best set up would be to have a first basic filter outside, then an UV light inside the water tank.
Once that will be done, we will be able to use AND DRINK the water from our borehole.
