The well is dry - what should I do? Repair and clean!
Well at one time we dug for a long time, as the water was at a depth of about 20 m. More precisely, the workers were digging, but under our sensitive guidance. Then deepened, having inserted a casing from the zinced steel.
Since that time a lot has passed, and all this time our well in the winter and in the summer gave us the purest key water. And the water in it was really key. If you approach the well closer and listen, you could hear the water in it constantly buzzing.
However, last spring the water level began to fall sharply. We even had to lower the pump several times. However, in one day, not at all perfect for us, the water level fell so much that, no matter how we lowered the pump, we could not get to the water. After the measurement it turned out that the water in the well was less than 20 cm. And it was a real disaster - the well dried up, and we were left without water.
Phone calls on advertisements about the device and repair of the wells were unsuccessful. Everyone was frightened by the non-standard situation with our well. We needed a creative approach to solving the problem and technical virtuosity of execution. Only on the second day of the search we managed to find well craftsmen who agreed to inspect our dry well and try to find a way out of the impasse.
Three of them came to the appearance of vigorous and savvy cops (the so-called builders of wells). Their tool was serviceable and varied: winches, collars, crowbar, lanterns, etc. We with hope have thought, children should consult.
They quickly dismantled a well house, and one of the diggers easily descended into the well. Long minutes of examination and waiting passed. Finally, the research explorer was raised by a gate to the surface. Full disappointment was on his face. The verdict was this:
- old casing made of galvanized sheet steel strongly rotted and deformed, through it sand seeps into the well and the water vein is washed;
- the water level fell by one and a half meters, judging by the tracks on the casing, and why - one of the underground forces is aware;
- It is necessary to change the casing, but the old, clamped by the ground, will be difficult to extract, but rather impossible;
- it is necessary to deepen the well, but at the bottom of the calcareous stones, composed of dense and durable layers. Stones must be pricked and raised - the work is extremely difficult, if at all feasible.
It's sad, but there's no other way. We did not want to drill a deep well at 160 m.
Firstly, it is expensive, and secondly, water from such a depth requires purification from iron and additional filtration, that is, a plant with an entire filter system is needed. And our well gave us the purest key water without any cleaning. The chance to revive the well was still there, and the diggers without a guarantee agreed to try.
Dismantling of the old well shell
The old hood was hooked with a cable and began to try to pull it out with a winch from the ground. It turned out not so simple, the cable cut through rusty iron, like a knife oil. It was necessary in the upper part to the rusty iron bolts with large washers to attach special plates to increase the area of grips. After this procedure, the winch managed to pull out the casing and raise it to the surface. Yes, for 15 years of service the galvanized sheet iron has turned into a rusty sieve. Therefore, the new casing was decided to be made of stainless steel.
Cleaning and deepening of the well with your own hands
When the cop went down into the well, he saw a miserable sight. The sandy soil with stones, which was previously held by the old rusted casing, now fell into the shaft of the well. Before I could get to the rocky base, I had to raise a lot of buckets on the surface with crumbling ground. It's good that the lowest part of the mine was previously cut down in the limestone layers, which itself did not collapse, and to some extent prevented the walls from complete destruction and shedding.
After cleaning the bottom of the well, there was practically no water in it. It should be noted that our well dried in the most waterless time - in April, when the water table is the lowest. During the winter period, all autumn water supplies are greatly exhausted by nature and man. Therefore, experienced diggers always try to dig and dig wells in March-April.
In the limestone layers there were numerous cracks through which water oozed. Obviously, this was the same water-bearing layer that fed our water well, but the water level in it fell almost to the bottom. The digger with great difficulty succeeded in stirring the calcareous stones with scrap, which they raised to the surface by ropes. With each developed layer of limestone, water became more and more, it had to be periodically pumped out by a drain pump. So it was possible to pass the mine in the limestone to a depth of a little more than a meter, and then there was a real quicksand - fine, almost like dust, water-saturated sand.
The pump could no longer cope with the pumping of water, and it was useless to dig further in the quicksand. For a few hours the water level rose by one and a half meters. In general, with such a significant inflow of water was already quite enough to install a pump to automatically feed it into the house. We could only put a new stainless steel casing inside the well shaft. But we still had to decide the important question: how to purify water from fine sand weighed in it.
Scheme of cleaning and deepening of the well.
Manufacturing and installation of a casing of a well
We purchased five sheets of stainless steel, from which we had to make a cylindrical casing with a height of 3,0 m and a diameter of 0,7 m. First of all, a casing with a height of 2,0 m was made of three sheets and then attached to it another one-meter section collected from the remaining sheets. For connecting sheets and sections, MB bolts with washers and nuts, also made of stainless steel, were used. Bolts and sheets of stainless steel are quite expensive, but for the sake of durability did not save.
The process of manufacturing the casing is quite simple, with difficulties it was necessary to encounter only when drilling holes in stainless steel. A lot of drills were blunted and broken before we managed to assemble a new casing. Special sealing in its manufacture should not be sought - groundwater must seep inside the casing.
So, the casing is ready, it remains only to lower it into the shaft of the well. Once again pumped out the water, if possible, cleaned the bottom of the washed sand and began to carefully lower the casing. One worker had to go down into the well to adjust the casing as it moved down. We calculated the diameter of the casing correctly, and he calmly entered the mine, cut through the limestone stones.
Having lowered the casing, water was again pumped out to clean the bottom and lay on it a half-folded fine food filter net that must clean the water coming from the sand into the well. The grid was tightly pressed against the casing and the bottom of the well, piled on it with granite stones measuring 50-70 mm.
Finally, all the installation work was completed, but the water in the well was still very muddy from the sand that came from the quicksand. But its level is quite decent - a little more than 1,5 m.
Pumping the well with your own hands
We had to pump the water for a long time, but the smallest sand from the quicksand continued to seep into the well. One thing was good - there was so much water that the pump barely had time to pump it out. For two weeks, we pumped water every day, but its crystal clearness was never achieved. The sand in the water was still, albeit in small quantities. Therefore, an additional filter of mechanical cleaning was put in the water supply system and put it into operation. And a month later, clean water flowed from the taps in our house again.
First, the filter was cleaned once a week, then - less often and less often. In the summer, when a lot of water was spent for irrigation, the well was fully pumped, and the water in it acquired its former purity. Now, as before, it all the time flows and quietly murmurs. It's nice to hear and it's nice to drink.
And yet - we have one sign. On Epiphany night, we must come to our country house and open a well. We hope that the powers of heaven will help him to always be with water. And this time our well was full. And, as you know, maybe this is not only our merit.
