The project involved the construction of water and sewer pipelines along Outer Ring road. The major works involved relocation of the existing DN 500 water pipeline and upgrading it to a new DN 600 spigot and socket epoxy coated steel pipeline. A total of about 17.159km of water pipelines were laid including 9.963km of DN 600 steel pipes, 60m of DN 500 steel pipes, 895m of DN 400 steel pipes, 359m of DN 300 steel pipes, and 1942m of DN 250 steel pipes and 900m of DN 200 steel pipes, among others. A total of 3548m of sewer pipelines of DN 600, 450 and 300 were also constructed.
The primary objective of the project was to relocate water and sewer pipelines that were within the road corridor so as to enable the construction of Outer Ring road.
