N2  -  The growing trend of construction projects, including water supply and sewerage lines, as well as the willingness of employers and investors to use new technologies requires careful technical evaluation and economics in accepting new materials and technologies before implementation, because this can avoid negative risks that lead to costs. One of the new materials that is used in water supply, sewerage and water transmission lines with high acidity has significantly increased GRP pipe, which due to the important characteristics of the pipe index, the position against corrosion, no need for Internal and external coatings and cathode protection and light weight have provided the acceptance of this pipe for a suitable replacement of pipes (steel, concrete, asbestos and diameters larger than 400 mm polyethylene). The cost of drilling and placement of the pipe in the drilling method is higher than the cost of preparing and purchasing the pipe for pipe check due to GRP reinforcement for use in the pipe jacking method is more than the open drilling method. The use of GRP pipes is a very good solution, considering that the country produces special GRP pipes, so the use of trenchless drilling can be economical in reducing the social and environmental problems that we see open drilling.
