Used Water


​​Singapore’s first proposal for handling of used water can be traced back to 1890 to the nightsoil system. By 1912, construction of new Sewage Disposal system had begun. Today, PUB is building a Deep Tunnel Sewerage System (DTSS), a superhighway for used water management.

Here you will find more information on how Singapore has managed the country’s used water through the years as well as the guidelines for protecting and managing our sewerage system.
