How to deepen a well

Question: How to deepen a well? I have a well at the cottage (7 w / b rings in the ground). There is little water, especially in summer. I want a well to deepen due to drilling (insert a pipe with a diameter of 320 mm). Is I really want to do and not ruined this pipe at all well? Suddenly the water will go away at all? Land in the country of sandy. Question from A. Ivanova, Moscow region

Answer: No, wrong. Lack of water in a 7-8 meter well testifies either about the wrong installation, or on the brand of perforations on the rings and the day of the mine. Manually dried a well with a diameter of 320 mm seems unlikely - it is necessary to cause a drilling machine. And in this case, your existing seven rings will be needed, since when the soil is notching, it will remain in the mine. And how to withdraw him from there? Yes, and the financial discount on 7 m from the drillings does not have to wait. That is, in the case of calling the drillings "On the water" it is advisable to equip the well separately from the existing one.

Yes, and search for water they will be at a depth of 50-70 m, in accordance with the map of the water horizons of the Moscow region. The submersible pump will also be required here, and the corresponding water intake equipment. Costs for 300 thousand rubles will be checked. However, back to your problem.

What can be advised real? In your region, and this is most likely the southeast of the Moscow region (it is there that the sandy soils are preferably located), the upper water horizon is located at least three meters. It is necessary to check whether the perforation perforation has previously performed, clean it, and then execute a new one. This is done by the perforator using the borrow with a diameter of about 20 mm. Starting with the fourth rings, counting from the top cutting of the well. And so right up to the seventh.
