Abyssinian well is called artesian wells, consisting of a narrow tube with a diameter of 25 mm to 45 mm.The rise is being pumped from the aquifer and in an hour you can get 2 or 3 m3 of water.It's a great way to organize the irrigation area in the country, which has no central water supply.If the performance of the well are not enough, you can build two sources.While in the first liquid is dialed, the latter is used.And well they get so compact that they are satisfied, even in the economic annexes or basements.
drinking water in the area
Terms of creating
dig the well can be on light sandy soils or melkoschebnistyh at depth of water in the soil not less than 20 m. The optimal length - 5-8 m. This is due to the method of pluggingpiles.On a hard or clay rocks, as well as finding a very deep aquifers drive pipe is simply not succeed.
Another problem with the device is sufficiently well piezometric water level, ie the distance from the surface to the water table.The pipe diameter is too small for a well for installation of the submersible pump.Therefore, to raise the water surface have to use a vacuum device.At normal atmospheric pressure, 746 mm Hg.Art.the height of the column of water is estimated to be 10.5 m, and in fact - about 8 m. If the distance is greater, no pump is not able to pick it up.It does not help even increase its capacity.
Preparations for drilling
well suited for drilling reinforced plastic or metal galvanized pipes length 1 or 2 m. As the immersion of their increasing, screwing the new segments.Tightness is very important to work well, so the connection seal with silicone or oil paint.Top dress with special sockets.
Water on the dacha
If the filter needle is made from a length of galvanized steel, the holes are drilled in the body size of about 8 mm uniformly staggered.Face close soldered stainless steel mesh.She will play the role of a coarse filter of sand and silt.Inside should be set as a fine filter.At the end of welded tapered tip size slightly larger than the cross section of the pipe.Then the drill will move easily in the interior of the earth.
Reinforced PVC pipe is also suitable for installation in a borehole.The filter needle from it is the same:
- perforated wall hacksaw;
- filter mesh is inserted inside the body and fused into it.

Technology for creating well
Abyssinian well drilling has its own distinctive features:
- point in the future the well dug a hole the size of about 1 cubic meter.
- top layer of the earth are the usual drill at shallow depth, has not yet go deep moisture level of the soil - quicksand.
- then started to hammer the pipe in the ground.This requires a "Drop-baba" - a weight of not less than 30 kg.You can use the discs from the bar.Proceed carefully so as not to slip past the aquifer level.
- When working in the pipe constantly pour water.When she begins to go drastically - the layer you want is reached.Then it is necessary to deepen the construction of another two feet or meters.Make sure to pile all the time remained vertical.
- As immersion into the soil pipe is extended nozzles, and slipped around her and rammed earth.
- After drilling the filter needle is washed with water under high pressure.
- mounted vacuum pump that works by creating a vacuum in the tube and muddy slurry is pumped up until the liquid is clear.
- To create an additional filtration circuit is poured into the hole marble chips.
- concreted area around the source that do not fall into the dirt.
All operations are performed quite simply, a matter of hours.Normal service life of Abyssinian well from 25 to 30 years.But there is a well working for more than two centuries.Installation requires no maintenance, except for replacing the fine filter once every few years.
If water still runs low, the tube can be removed, move and make the source to another location.Many such places the well does not need enough 1,5-2 m2.
