Megaproject: Singapore’s Deep Tunnel Sewerage System | Tomorrow City | Part 1/3

Singapore is geologically challenged and with climate change, a growing population and economic competition – the country needs land to develop. To overcome the pervasive space challenge, the country is investing in megaprojects that will help overcome these problems and take it into the next century. One such project is the Deep Tunnel Sewerage System. By using new technology, this infrastructure will also take Singapore’s sewage management into the next century. But tunnelling under built up areas is less than ideal. The team has to move massive tunnel boring machines that are each the length of 10 SBS buses underground. And that’s not the biggest challenge.
