Abyssinian well - accessible source of water in a country house

FORUMHOUSE users know that a comfortable life in the country is impossible without a reliable source of water supply. The first thing that comes to mind - to dig a well or drill a borehole, but both of these methods have drawbacks. Drilling is expensive and requires special equipment, and independent digging wells under the force is not for everyone. However, there is a third, more affordable option - Abyssinian well, or as it is called, "needle".

Abyssinian well: what the device 

Abyssinian well - a water intake metal or plastic pipe with a diameter of 2.5-4 cm, set in aquifer to a depth of 10-15 m. In the lower part of the tube is a filter tip and the borehole, so-called "needle". On top of the tube set a manual pump or pumping station operating on electricity.

Nedrabur (participant FORUMHOUSE):

Abyssinian attracts suburban residents the opportunity to solve the problem of water supply of your site, baths and even a country house residence without arrival of heavy machinery.

Abyssinian performance, depending on the "power" aquifer may reach 3-5 m3 per hour.

Benefits Abyssinian wells

Among the advantages of Abyssinian well include:

• The relative cheapness: well you can do yourself, and everything necessary for its device - to get to the nearest the building market;
• High manufacturing speed: on average it takes several hours device;
• Ease: it can be arranged in a limited space (suitable cellar at home, basement or garage), and at any location area;
• Ease arrangement not require the use of special heavy machinery or equipment drilling sidings for motor vehicles;

How to make a filter for the Abyssinian wells

Durability of the "needle" in many respects depends on the chemical characteristics of the aquifer and the effectiveness of its filter.

Alextr61 (Member FORUMHOUSE):

A good filter is recommended to do so: buy galvanized thick-walled tube of 1.5 m in length Cut the thread from both sides.. On the base pipe is screwed pointed tip "needle" (it pushes the ground) with a diameter of 20 mm larger than the diameter of the pipe (nozzle seat connection pipe can boil for strength).

From the base of the pipe need to retreat to 0.5 m. This distance is subject to the sump under the sand. Then, every 50 mm staggered drill holes of 10 mm diameter. pipe section with holes wrapped stainless steel wire of 1.5 mm diameter. Thereafter further wound into two layers stainless mesh with small diameter holes.

Mesh top not boil, and fasten it with clamps made of stainless steel. For better filtration tube can wrap the geotextile and fix it with steel clamps.

If in the aquifer contains large amounts of impurities, as well Abyssinian filter manufactured technological problems, it is silted up, which will lead to a reduction in water quality and rapid exit of system.

we talked in detail on FORUMHOUSE, how to make a filter for Abyssinian well and which technical requirements apply to him.

Drawbacks of the Abyssinian wells

For all its advantages, this type of water has several disadvantages. Abyssinian well possible to arrange not all - there are areas where a "needle" is not even communicate better.

• Abyssinian well established "in the sand." If there is in the area of ​​thick layers of clay, limestone and large stones device such wells is impossible or not economically feasible;
• For lifting water from it is necessary to use a pump station (in a small diameter borehole install submersible pump impossible). The distance from the top of the well to the water surface in the tube should not exceed 8 m, and itself "needle" can be clogged and 10-15 meters. If the distance to the water surface more than 8 meters, it will be installed below the pumping station, in digging a pit or to arrange a subfield caisson outside. If the aquifer is lower (by 20 m or more), then the pumping station can not simply lift the water from that depth.

Abyssinian well: necessary conditions

Before you get to work on the device of the "needle", you need to understand whether it is suitable to your site. Therefore, first, we examine the depth of the aquifer (even in different areas of up to 250 meters may fluctuate in the vicinity of Moscow depth finding aquifer) and ground appearance.

When choosing a water supply source should be guided by the existing water wells of similar design, in close proximity to your site. And in their absence - exploratory drilling and other significant geophysical survey methods.

To find water different methods are used: from dowsing to geodetic maps that displayed soils and aquifers.

Abisinskie well and Parcel

Much depends on the individual characteristics of the site. That efforts and money are not wasted, and the well is not abisiyskaya remained useless monument of your carelessness, to her self device should clarify a number of points:

• The depth of the aquifer. This can ask neighbors water level in their wells, and also to measure the distance to the water surface. If the depth of the wells is not more than 12-15 m, and the distance to the water surface is not more than 5-10 meters, then it is likely that the "needle" can provide a home with water;
• Estimated water quality. Abyssinian - well shallow foundations, and the aquifer can be prone to bacterial and chemical contamination. Therefore, you must find out in advance where there are septic tanks, cesspools, is there near the sources of chemical contamination. Sometimes, even at this stage, it is necessary to abandon the well device;
• Supposed place device "needles". It is possible to arrange in the house, in a technical room, then the pump station and other equipment will be protected from adverse weather conditions and very well from freezing in winter (if the house CoML). If the hole is supposed to equip the area, it is best to place it close to home. In this case, entry of water into the house will have hands to dig a trench under the highway by staging a caisson or insulated cover, which leads to additional costs;
• Estimated needle debit. It largely depends on the saturation of the aquifer. An indirect indication may be the level of water in the neighboring wells. You should also find out if they dry up in summer.

Good water-bearing formation at a "needle" located in the core with a large (river) sand.

Nedrabur (participant FORUMHOUSE):

The most advanced design Abyssinian wells not save if the aquifer has a low fluid loss and low power.

If Abyssinian fluid loss is small, will not buy and install a storage container for water at 500-1000 liters.

Fluid loss already arranged Well, you can learn so - note the time of filling measuring cup and see how much is filled with 10-liter bucket. Without stopping pumping, repeat the procedure even 2-3 times in 10-15 minutes, and get an average value - specific wells debit.

How to make your own Abyssinian well: manual methods

There are two basic ways well Abyssinian device:

• Plugging wells steel "sissy."

• Drilling using a small-sized screw installation.

Auger drilling suggests the presence of a special and not always available hardware, so a closer look at the manual method or wells.

Abyssinian well: clogging of steel "baba"

When driven well, "Baba" on the tube wear special steel ingots weighing 40-50 kg, with a hole in the center and two handles on the sides. The pipe is fixed "podbabok" - a special tightening bolts clamp. "Podbabok", being a stop for the "woman", when struck conveys all of the energy tube and "needle", which gradually enters into the ground. As we move deeper into the rock pipe on the pipe, one after another, through further couplings screwed to the knee until the "needle" reaches the predetermined depth.

Also at well head pipe can be screwed special nozzle on which bumps will be applied. This method is well Abyssinian device demanding quality threads, as on it falls heavy workload.

Fludik (participant FORUMHOUSE):

"Igloo" I was picking up on steel couplings and a tow (flax) with pasta, as cast iron fittings from the blows may burst. During driving constantly pulled up column key clockwise.

To control the depth of immersion of the column and facilitate the flow of soil into the pipe is filled with water.

Upon reaching the aquifer water with the characteristic noise out of the tube. You can then finish off the column for another meter (to filter all the water was in the reservoir) and try to pump the "needle".

Yuri (participant FORUMHOUSE):

When filling water into the tube or it can go into the space between the pipe and the clay / dry sand or into the aquifer. The swing column manual piston pump. Only then connect the electrical.

Alextr61 (participant FORUMHOUSE):

After plugging in my first Abyssinian was muddy water with fine sand and slurry.

After pumping about 500 liters of water went clean. Somewhere after 1000 liters of water was used for drinking.

As the pumping wells and around precoating filter the "needle" water lenses water will go all the cleaner and cleaner. We offer you to get acquainted with our article, which discussed in detail Abyssinian device well by plugging steel "Baba".

Abyssinian well: plugging rod

There is another method for plugging a well - on the inside of the pipe, using a metal rod - thick rebar.

BCCH (participant FORUMHOUSE):

 I think it is better not to score well, "Baba" and bars.

In this case the armature hits the back of the "needle", placed at the head of the first pipe section upstream of the filter. The tip must be welded to the well pipe.

Alextr61 (participant FORUMHOUSE):

Armature I scored as follows: dug a hole about half meter depth and set in her first tube with the tip.

I placed over the pipe tripod, and through the block, on a cable and lowered into the pipe steel rod weighing 40 kg. He scored on a swing.

If the weight of the rod is not enough, then the deepening of the well to each other are screwed the new section of the bar.

OSB-Neva (Member FORUMHOUSE):

I came to the conclusion that inch pipe to score better on the outside "baba" and pipe inch and a quarter is better inside the bar.

well rod driving method eliminates the possibility of the device "needles" in a limited space, in the subfield.

It would seem that a driven wellbore device is to use only a solid metal tube. However, a user with the nickname FORUMHOUSE maxims Sanych managed to score a polypropylene tube!

OSB-Neva (Member FORUMHOUSE):

I did not want to use the tube of ferrous metal or galvanized. Pipe made of stainless steel is expensive. Therefore, I decided to score a polypropylene tube. Bought 6 m tube sorokovke reinforced with fiberglass. Made meter and scored filter rod inside the well. Everything works fine. Pipe broke. Now, I think and neighbors to do so.

In conclusion, it is worth noting that the standalone unit Abyssinian wells is not a highly complex task, and with the right approach, afford any!

On FORUMHOUSE will help you understand, hit or drill hole Abyssinian. You will be able to participate in an exciting discussion on, Abyssinian well what it is: a great way to permanently solve the problem of water supply for a country house or guaranteed by siltation in the first years of operation, See the photo report Abyssinian device independent wells and to know, how to choose a pump station.
