Development of a special technology for manufacturing of filtering tubes (preferably fine steel) for water extraction from big depth with regard optimal energy bilance and minimal exploitation of resources. This comprehends the development of special manufacturing machinery depending on the developed technology. The filtering tubes shall be made by non cutting shaping of drawn material (fine steel wires with suited profile). The winding wire will be fed around axial supporting bars in a defined, adjustable distance. All points of intersection will be welded. The filter splits can vary by the defined distance of winded wire depending on the geological conditions (grain size).
