Industrial Water Works

Overview

​​Jurong Industrial Water Works (JIWW) was set up to reclaim wastewater effluent of the Ulu Pandan Water Reclamation Plant (UPWRP). The purpose of wastewater effluent reclamation is to provide an alternative source of water for industries in the Jurong and Tuas Industrial Estate.

From an original capacity of 45,000 m3 per day, the current capacity is increased to 125,000 m3 per day over the years to cater for industries set up on Jurong Island and Tuas South.

With effect from April 2007, PUB has stopped supplying industrial water to the industries in Jurong/Tuas Industrial Estate as NEWater has replaced industrial water as an alternative source of water. Currently, industrial water is only supplied to the industries on Jurong Island.
