The above sections were done using specialized Ploughing machines that plough the HDPE sub-duct directly into the ground at a depth of 1.2m at the same time laying a plastic warning tape at a depth of 0.6m. The ploughing machine does this without opening up a trench while achieving a very uniform level of the sub-duct and warning tape. In areas that are rocky the ploughing machine cannot penetrate and hence manual trenching is done with use of compressors. After the HDPE pipes are laid, the optical cable is blown or water floated into it.
