If the quality of the water has fallen at the cottage, and the well is almost dry, then you need to perform wells deepening with your own hands.
We all know that this building is an important element of the suburban area.
However, even regular cleaning and maintenance will not be able to maintain its operational properties.
Before making a deepening of the well with your own hands, exclude the following reasons: the construction of wells or a larger well in the neighborhood, drought, freezing or natural fluctuations of the soil.
Rate, a broken well or natural causes can be done in one month. If the water source is still dry, then you can start repairing it.

Preparatory stage
The ways of deepening may be different, however, before any of them the following measures should be carried out.
The first is to evaluate the feasibility of work.
The well must be working, not warped, drinking water can be used, in depth the well consists of 10 or more rings, the rings are not displaced by more than 4 centimeters.
If it does not match these parameters, then you have to dig a new one.
The deepening of the well in the country is best done at a time when the water table is low enough. In October or November, it will be easier to clean, the water level is lower.
Before you start, you need to make a calculation - how much water comes every day, how much soil can keep the walls unchanged, at what depth water lies, and do geological exploration.
Deepening with plastic rings
The first thing to do is to dismantle the ground part of the well.
Next, the water is pumped out and the structure is cleaned from debris, mud and other things.
You also need to make reinforcement seams.
The inner rings are fixed with metal brackets, at least two for each joint.
Special attention is paid to the upper ring.

Deepening with rings of smaller diameter
This technology requires a pipe made of plastic of smaller diameter than the size of the inner ring of the shaft, and at least one meter. A pipe of this diameter can easily pass through to the end.
In a pipe it is necessary to make not less than 50 holes in diameter of 20 millimeters. On the inside, place a stainless steel grid with small cells. This will be a filter.
Special for this work drills, otherwise they are called bailers, dig a meter pit and put a prepared plastic pipe. The top of the pipe should not be covered with water.
To pump water from the bottom, use the pump. For these works, an electric pump is suitable for working at depth.
After this, start moving the pipe down, drilling a well a distance of two to three rings in the shaft.
Next comes the cleaning: sand, debris, soil is removed, water is pumped from the bottom.
After the bottom is cleaned, lower the rings of concrete of smaller diameter than those from which the well is built.
Rings are fastened with metal brackets, special attention is paid to the joints of old and new rings.
The video of the groove with smaller diameter rings can be viewed below.

Deepening the well on quicksand
This method is used when the water source is located on a complex area of ground, the so-called sailing. The groove must be made by hand.
Buckets are used to clean the mine from the ground.
A plastic pipe with rigid ribs is lowered inwards simultaneously with the process of deepening.
Instead of a pipe, it is possible to use rings made of plastic with threaded ends connected by a waterproof sealant. As soon as the water starts arriving fast enough, the groove is stopped.
The opening between the walls of the shaft and the rings is covered with a mixture of sand and cement in a proportion of 1 to 5.
This work is laborious enough, cleaning from the ground is done manually. And since the soil is quicksand so as not to get stuck, it's necessary to work on a wooden raft or special swings.
Note that with this method the inner pipe will be along the entire length, unlike the first one, where the concrete rings of smaller diameter than the inner ones are joined to each other.
Watch the video how a groove is made on quicksand by plastic rings.

Final stage of
Having made the reconstruction of the structure at one of these methods at the summer residence, it is necessary to conduct final events.
With a mixture of cement and liquid glass, all seams and potholes are closed, debris is cleaned, a 15 centimeter filter is placed on the bottom( river pebbles, it can be replaced with coarse gravel).
This will fix the soil and reduce water pollution.
In conclusion, do not forget to disinfect chlorine or manganese.
