Rochor River

The Rochor River is a canalized river in Singapore's Central Region, located near Kallang. The river is approximately 0.8 kilometers long. The Rochor River, which originates beneath Victoria Bridge and drains into the Kallang Basin, is a continuation of the Rochor Canal.

The Rochor Canal extends upstream to the intersection of Jalan Jurong Kechil and Upper Bukit Timah Road; the Rochor River's source is Beauty World MRT station, which has a canal that goes to the Kranji Reservoir and may be extended to Tengah as part of the Deep Tunnel Sewerage System. The term "Rochor Canal" is also the name of a subzone inside Rochor's planning area.

The Rochor River has been managed and widened by canals in the past to control floods in Bukit Timah. While the Rochor River is clearly the lower channel, the Victoria Bridge upstream uses the names Rochor Canal or - even farther upstream - Bukit Timah Canal, as shown on numerous maps. The canal has been cleaned and rebuilt several times throughout the years.

Because this was ineffective, the Singapore National Water Agency PUB's Bukit Timah Flood Alleviation Scheme (BTFAS) (constructed in the 1960s) added two more service channels: the Bukit Timah First Diversion Canal and the Bukit Timah Second Diversion Canal (1990s, 4.4 km long, to Kallang Basin). They are partly subterranean, running through tunnels.
