B.3.0 DESCRIPTION OF PROCESS

A description of the process or storage involving the hazardous substances
and an indication of the conditions under which it is normally held;

The plant is situated about two (2) km from Segamat town. The plant is designed to
supply 45 MLD (KT1: 13.1 MLD, KT2: 31.36 MLD) of treated water to industrial and
residential areas particularly within Segamat.

The KT1 & KT2 WTP receives raw water intake from Segamat River. The following
Table B.3.0 summarizes the main elements of the water treatment process and their
functions:
