DESCRIPTION
The Deep Tunnel Sewerage System is a mega infrastructure project aimed to meet Singapore's needs through the 21st century.
The concept of the DTSS is to use link sewers to intercept flows from existing sewers upstream of the existing STWs. These flows will be channeled by gravity via deep tunnels to 2 centralised wastewater treatment plants strategically located at the southern coastal areas, with the treated effluent discharged through deep sea outfalls.The DTSS comprises of 4 components: North and South Tunnels; new wastewater treatment plants; deep sea outfalls and link sewer network.
T-03 Paya Lebar Tunnel, is part of the North and South tunnels.
