“There isn’t a dull moment for me. There are many challenges working on a major project that is as complex as DTSS. ” – Mark Wong, Senior Engineer, Electrical Engineering graduate

When I first joined in 2008, I was an Engineer working at the Changi Water Reclamation Plant, which is the heart of the Deep Tunnel Sewerage System (DTSS) Phase 1. At the Changi plant, I was part of the team in charge of the treatment of used water. As a young Electrical Engineer then, I had the opportunity to get hands-on experience and learn from the seniors about the operations and maintenance of such a mega-plant. With this experience, I was subsequently posted to do policy and planning work before moving to my current role in a project unit to deliver Phase 2 of the DTSS.

There are many challenges working on a major project that is as complex as the DTSS. Under DTSS Phase 2, we intend to extend some 40km of deep tunnel sewers (depth of between 50-60 m) and 60km of link sewers in the western part of Singapore to collect all its used water and channel it to an advanced water reclamation plant in Tuas. My work is exciting as we are always learning new things and developing different approaches to address the challenges we face. The DTSS Phase 2 project is ongoing and is expected to be completed by 2025.

In PUB, you will always have an active role to play in the future of Singapore’s water story. Join us in shaping the future. Visit www.pub.gov.sg
