Proposed Sewers in Upper Changi Road East Areas
The objective of this project is to expand the sewerage network in North-eastern Singapore.
The proposed sewerline is located within Singapore urbanised and high-density housing area. Total length of the sewerline is about 6km from the Old Tampines Road to Upper Changi Road East, with about 30 manholes intermittently spaced along the sewerline alignment. The new sewerline will have an internal diameter of 2,500mm, which will be installed by pipe-jacking method at depths of between 15 and 35 metres, while the manholes will be constructed by deep excavation works.
