Lorong Halus means “Thin/Tiny Lane” in Malay. In the 1970s, Lorong Halus was predominantly a farming area with several Malay rural villages such as Kampong Sungei Blukar and Kampong Teban, ponds and coconut and rubber plantations. A large part of the area had formerly been used as a sewage ground (for night-soil collection) and a refuse dump. The sewage ground was shut down in the 1980s following the end of the local night-soil industry in Singapore at around that time, while the dumping ground was closed down on 31 March 1999, and since then all of Singapore's garbage has been sent to Pulau Semakau Landfill (incinerated beforehand) just off the mainland's southern coast. Today, much of the area has been restored to its original natural state as a coastal wetland open to the general public.
