The Western Water Catchment is a planning area located in the West Region of Singapore. The planning area borders Tuas and Pioneer to its south, Sungei Kadut, Choa Chu Kang and Tengah to its east, Jurong West to its southeast, Lim Chu Kang to its north and the Straits of Johor to its west. It is the largest planning area by land area, covering nearly a tenth of Singapore Island. It is also one of the two main water catchments in Singapore, the other being Central Water Catchment. The area currently houses four reservoirs, Tengeh Reservoir, Poyan Reservoir, Murai Reservoir and Sarimbun Reservoir. Part of the Western Water Catchment is also a live-firing area in which it is used by the Singapore Armed Forces for training purposes. The SAFTI Live Firing Area commenced operations in 1968 and was revamped in 2008, the eastern part began operations in 2002 and has been extended to Lim Chu Kang Tracks 11 and 13. History The SAFTI Live Firing Area was drawn out in 1967, Before the drawing-up and gazetting of the live-firing zone, most residents and occupants living within the affected boundaries were shifted to Boon Lay as its pioneer residents and factories there were relocated to the Jurong Industrial Area, leaving only a few villages behind (all were gone by the early 1990s). On 14 July 1968, four villagers died and nine others were injured in the live-firing area (near Kampong Berih, one of many rural villages in the area) and seven other villagers snuck into Pasir Laba (on the coastline of the Johor Straits) by sampans to pick durians and rambutans from the many fruit trees in the forest there. These villagers were injured by mortar rounds in their attempt to collect fruits. There are many cases of trespassers in the live firing area. Previously, there was also a military fort called Pasir Laba Battery as a WWII gun battery from 1936 to 1942. It was therefore demolished in 1970s although it is located at both Wrexham and Bajau area. Several of the WWII gun battery historical remains were seen at the junction of Wrexham Drive and Wrexham Road. Infrastructure Military There are seven main military bases in the Western Water Catchment. These include Pasir Laba Camp, Choa Chu Kang Camp at Lorong Danau (where the RSAF's 201 Squadron is based; it has Fighter control, SAM control, Surveillance and ASP), Sungei
