Abyssinian well – the simplest design for water lifting which installation gives opportunity not envy from the centralized water supply and therefore it is essential to save on purchase of the expensive water-pressure equipment. However in spite of the fact that the Abyssinian well is the real find both for summer residents, and for permanent residents of country cottages, is at this equipment both advantage, and some shortcomings.
The Abyssinian well represents the well with a diameter of 25 mm and up to 30 m long on which lower part the special filter consisting of perforation and close-meshed grid is installed. The upper part of Abyssinian well is equipped with the pump.
It is possible to construct Abyssinian well as on open area, and indoors.
We build Abyssinian well: advantages of the equipment
The most clear advantage of the Abyssinian well in comparison with normal well is the low cost of its installation. So, for construction of normal well it is necessary to buy large number of expensive concrete rings which besides still it is necessary to deliver to the place and to establish. The total base bid of normal well turns out very rather big. Construction of the Abyssinian well which is not needing laying of concrete rings can cost several times cheaper.
The water extracted from Abyssinian well does not demand additional treatment and cleaning.
Obvious advantage of construction of Abyssinian well is also the speed of process of the equipment of the well borrowing from five to ten hours, seasonally and weather patterns. It is possible to be engaged in construction of the Abyssinian well in the conditions of limited space, used for this technician freely finds room in the closed room 2-2.5 m high and 1.5 m wide. It can be as the basement, garage, cellar or viewing hole, and kitchen of residential building. The airtight joint which is formed in the course of construction of Abyssinian well completely excludes penetration into water of garbage, dirt and the impurity which are available in air. On the performance the Abyssinian well does not concede to the classical well at all and has ability to lift from 10 to 60 liters of water an hour. Life cycle of this surprising device makes 25-30 years.
Shortcomings of Abyssinian well
The main lack of Abyssinian well is the complexity in hit on water-bearing stratum of soil. The inexperienced worker can simply slip water layer when drilling and chuck in pipe too deep water that will result in uselessness of use of the well. In spite of the fact that depth of the Abyssinian well can theoretically reach 30 m, the distance to water layer has to make no more than 8 m. The fact is that work of Abyssinian well provides vacuum method of water supply at which the size of water column should not exceed 9 m.
At bedding of water more than on 8 m construction of Abyssinian well is impossible.
Construction of Abyssinian well and with some geological features of the area, for example presence of layer of clay more than 8 m high is considered impossible.
