What the Western Water Catchment is
At 69.75 square kilometres, the Western Water Catchment is the largest of URA's 55 planning areas. It lies in the West Region between Choa Chu Kang, Tengah, Jurong West, Pioneer, Tuas, Lim Chu Kang and Sungei Kadut. Much of it is reservoir catchment and military training land with restricted access. SingStat recorded 590 residents in June 2026, all of them in the "other" dwelling category rather than in flats, condominiums or houses.

Stations announced with a date (LTA):

| Tawas | JW2 | 2028 |
| Nanyang Gateway | JW3 | 2029 |

LTA lists Tawas, the end of the first stage, for 2028, and the third stage, which extends the branch to Nanyang Gateway, Nanyang Crescent and Peng Kang Hill, for 2029. URA's Master Plan 2025 rail layer places all four inside this planning area, near Nanyang Technological University.
